If input is null, returns empty string. Otherwise returns original input. After using this method, you can use all string methods without the danger of null exception.

public static string NullStringToEmptyString(this string input)
{
	if (input == null)
	{
		return string.Empty;
	}

	return input;
}

Example

string myString = null;
myString = myString.NullStringToEmptyString();
myString = myString.ToLower();// some operation with no need for null check
