How do I convert a single char to a string?

Question

I\'d like to enumerate a string and instead of it returning chars I\'d like to have the iterative variable be of type string. This pro

Answer 1

With C# 6 interpolation:

char ch = 'A';
string s = $"{ch}";

This shaves a few bytes. :)

Answer 2

It seems that the obvious thing to do is this:

String cString = c.ToString()

Answer 3

Create an extension method:

public static IEnumerable<string> GetCharsAsStrings(this string value)
{
    return value.Select(c =>
           {
                //not good at all, but also a working variant
                //return string.Concat(c);

                return c.ToString();
           });
}

and loop through strings:

string s = "123456";
foreach (string c in s.GetCharsAsStrings())
{
    //...
}

Answer 4

Did you try:

String s = new String(new char[] { 'c' });

Answer 5

Why not this code? Won't it be faster?

string myString = "Hello, World";
foreach( char c in myString )
{
    string cString = new string( c, 1 );
}
