This code works fine on wpf.

In my code list1 will work but if convert a string to a list of char and change again to string it showing error of : can't convert from char[] to string []. need suggestion.

here's the code :

        string x = "hello";
        List<char> list = x.ToList<char>();
        //error
        string combindedString = string.Join(",", list.ToArray());
        string xz = string.Join("", list);
        //---
        //okay....
        List<string> list1 = new List<string>()
                                    "Red",
                                    "Blue",
                                    "Green"
        string output = string.Join("", list1.ToArray());
                Ahhh you're using the old version of Unity. That version used .Net 3.5 when a char[] didn't implement IEnumerable<char>

Well I suspect the source of your issue still lies with using the older .Net Framework that is default with Unity, 3.5 I believe. You have some options, to work around the problem though: 
You can target an update framework, I believe Unity supports up to 4.6.1 in experimental mode.
You can work around converting a char[] to string.
Or just use the string constructor:
A simple example:
[Test]
public void StringTest()
    string x = "hello";
    List<char> list = x.ToList<char>();
    string newStr = new string(list.ToArray());
    Assert.IsTrue(newStr == x);
                Another way you might try is to convert the list<char> into an array<char> and then create a string like so: string original = new string(array<char>); Not sure how well that would do on performance though :) You didn't mention that in your post
