Int32

Remarks

Int32 is an immutable value type that represents signed integers with values that range from negative 2,147,483,648 (which is represented by the Int32.MinValue constant) through positive 2,147,483,647 (which is represented by the Int32.MaxValue constant. .NET also includes an unsigned 32-bit integer value type, UInt32 , which represents values that range from 0 to 4,294,967,295.

Instantiating an Int32 Value

You can instantiate an Int32 value in several ways:

You can declare an Int32 variable and assign it a literal integer value that is within the range of the Int32 data type. The following example declares two Int32 variables and assigns them values in this way.


    int number1 = 64301;
int number2 = 25548612;
    
     let number1 = 64301
let number2 = 25548612
     
      Dim number1 As Integer = 64301
Dim number2 As Integer = 25548612

You can assign the value of an integer type whose range is a subset of the Int32 type. This is a widening conversion that does not require a cast operator in C# or a conversion method in Visual Basic but does require one in F#.


    
     
      
       sbyte value1 = 124;
short value2 = 1618;
int number1 = value1;
int number2 = value2;
       
        let value1 = 124y
let value2 = 1618s
let number1 = int value1
let number2 = int value2
        
         Dim value1 As SByte = 124
Dim value2 As Int16 = 1618
Dim number1 As Integer = value1
Dim number2 As Integer = value2

You can assign the value of a numeric type whose range exceeds that of the Int32 type. This is a narrowing conversion, so it requires a cast operator in C# or F#, and a conversion method in Visual Basic if Option Strict is on. If the numeric value is a Single , Double , or Decimal value that includes a fractional component, the handling of its fractional part depends on the compiler performing the conversion. The following example performs narrowing conversions to assign several numeric values to Int32 variables.


    
     
      
       
        
         
          long lNumber = 163245617;
try {
   int number1 = (int) lNumber;
   Console.WriteLine(number1);
catch (OverflowException) {
   Console.WriteLine("{0} is out of range of an Int32.", lNumber);
double dbl2 = 35901.997;
try {
   int number2 = (int) dbl2;
   Console.WriteLine(number2);
catch (OverflowException) {
   Console.WriteLine("{0} is out of range of an Int32.", dbl2);

   int number3 = (int) bigNumber;
   Console.WriteLine(number3);

You can call a method of the Convert class to convert any supported type to an Int32 value. This is possible because Int32 supports the IConvertible interface. The following example illustrates the conversion of an array of Decimal values to Int32 values.


    
     
      
       
        
         
          
           
            
             decimal[] values= { Decimal.MinValue, -1034.23m, -12m, 0m, 147m,
                    199.55m, 9214.16m, Decimal.MaxValue };
int result;
foreach (decimal value in values)
   try {
      result = Convert.ToInt32(value);
      Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.",
                        value.GetType().Name, value,
                        result.GetType().Name, result);
   catch (OverflowException) {
      Console.WriteLine("{0} is outside the range of the Int32 type.",
                        value);
// The example displays the following output:
//    -79228162514264337593543950335 is outside the range of the Int32 type.
//    Converted the Decimal value '-1034.23' to the Int32 value -1034.
//    Converted the Decimal value '-12' to the Int32 value -12.
//    Converted the Decimal value '0' to the Int32 value 0.
//    Converted the Decimal value '147' to the Int32 value 147.
//    Converted the Decimal value '199.55' to the Int32 value 200.
//    Converted the Decimal value '9214.16' to the Int32 value 9214.
//    79228162514264337593543950335 is outside the range of the Int32 type.
             
              let values = 
    [| Decimal.MinValue; -1034.23M; -12m; 0M; 147M
       199.55M; 9214.16M; Decimal.MaxValue |]
for value in values do
        let result = Convert.ToInt32 value
        printfn $"Converted the {value.GetType().Name} value '{value}' to the {result.GetType().Name} value {result}."
    with :? OverflowException ->
        printfn $"{value} is outside the range of the Int32 type."
// The example displays the following output:
//    -79228162514264337593543950335 is outside the range of the Int32 type.
//    Converted the Decimal value '-1034.23' to the Int32 value -1034.
//    Converted the Decimal value '-12' to the Int32 value -12.
//    Converted the Decimal value '0' to the Int32 value 0.
//    Converted the Decimal value '147' to the Int32 value 147.
//    Converted the Decimal value '199.55' to the Int32 value 200.
//    Converted the Decimal value '9214.16' to the Int32 value 9214.
//    79228162514264337593543950335 is outside the range of the Int32 type.
              
               Dim values() As Decimal = { Decimal.MinValue, -1034.23d, -12d, 0d, 147d, _
                            199.55d, 9214.16d, Decimal.MaxValue }
Dim result As Integer
For Each value As Decimal In values
      result = Convert.ToInt32(value)
      Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.", _
                        value.GetType().Name, value, _
                        result.GetType().Name, result)
   Catch e As OverflowException
      Console.WriteLine("{0} is outside the range of the Int32 type.", _
                        value)
   End Try   
' The example displays the following output:

You can call the Parse or TryParse method to convert the string representation of an Int32 value to an Int32 . The string can contain either decimal or hexadecimal digits. The following example illustrates the parse operation by using both a decimal and a hexadecimal string.


    
     
      
       
        
         
          
           
            
             
              
               
                string string1 = "244681";
try {
   int number1 = Int32.Parse(string1);
   Console.WriteLine(number1);
catch (OverflowException) {
   Console.WriteLine("'{0}' is out of range of a 32-bit integer.", string1);
catch (FormatException) {
   Console.WriteLine("The format of '{0}' is invalid.", string1);
string string2 = "F9A3C";
try {
   int number2 = Int32.Parse(string2,
                            System.Globalization.NumberStyles.HexNumber);
   Console.WriteLine(number2);
catch (OverflowException) {

catch (FormatException) {
   Console.WriteLine("The format of '{0}' is invalid.", string2);
// The example displays the following output:

    let number1 = Int32.Parse string1
    printfn $"{number1}"
| :? OverflowException ->
    printfn "'{string1}' is out of range of a 32-bit integer."
| :? FormatException ->
    printfn $"The format of '{string1}' is invalid."
let string2 = "F9A3C"
    let number2 = Int32.Parse(string2, System.Globalization.NumberStyles.HexNumber)
    printfn $"{number2}"
| :? OverflowException ->
    printfn $"'{string2}' is out of range of a 32-bit integer."

    printfn $"The format of '{string2}' is invalid."

                   value as an integral string with no leading zeros, you can call the parameterless
                   
                    ToString()
                   
                   method. By using the "D" format specifier, you can also include a specified number of leading zeros in the string representation. By using the "N" format specifier, you can include group separators and specify the number of decimal digits to appear in the string representation of the number. By using the "X" format specifier, you can represent an
                   
                    Int32

                         In addition to working with individual integers as decimal values, you may want to perform bitwise operations with integer values, or work with the binary or hexadecimal representations of integer values.
                         
                          Int32
                         
                         values are represented in 31 bits, with the thirty-second bit used as a sign bit. Positive values are represented by using sign-and-magnitude representation. Negative values are in two's complement representation. This is important to keep in mind when you perform bitwise operations on
                         
                          Int32
                         
                         values or when you work with individual bits. In order to perform a numeric, Boolean, or comparison operation on any two non-decimal values, both values must use the same representation.
                        
                        
                         Thread Safety
                        
                        
                         All members of this type are thread safe. Members that appear to modify instance state actually return a new instance initialized with the new value. As with any other type, reading and writing to a shared variable that contains an instance of this type must be protected by a lock to guarantee thread safety.
