Make first character of a string upper case in asp.net

Couple of days ago I got requirement of make first character of a string upper case in asp.net. I found but unable to get any built-in function available in .net so after some sort of coding, I develop my own function.

 
public static string MakeFirstCharUpper(string inputstring)
{
    if (String.IsNullOrEmpty(inputstring))
        throw new ArgumentException("ARGH!");
    return inputstring.First().ToString().ToUpper() + String.Join("",inputstring.ToLower().Trim().Skip(1));
}

So that’s it. Just you have to call this function and you will get desired output.

Happy Coding!!!
