Mid function in C#

Although it's possible to reference VB.Net's Mid() function from C#, there's no need to do so when you can use the String.Substring() method instead.

For example:

string s  = "This is a string";
string t  = s.Substring(5, 2);
Console.WriteLine(t); // 'is'

has the same effect as:

Dim s As String = "This is a string"
Dim t As String = Mid(s, 6, 2)
Console.WriteLine(t)

The only thing to note is that Substring() uses zero-based indexing but Mid() uses one-based indexing.
