BestPractice - Transform first character of a string into lower case

Question

I\'d like to have a method that transforms the first character of a string into lower case.

My approaches:

1.

public static string ReplaceFir         


        

Answer 1

The fastest solution I know without abusing c#:

public static string LowerCaseFirstLetter(string value)
{
    if (value?.Length > 0)
    {
        var letters = value.ToCharArray();
        letters[0] = char.ToLowerInvariant(letters[0]);
        return new string(letters);
    }
    return value;
}
