In WPF this can be uses to check if a string is a valid variable name. But it does not regognize reserved strings like "public".

// works only in WPF!
public static bool CheckIfStringIsValidVarName(string stringToCheck)
{
    if (string.IsNullOrWhiteSpace(stringToCheck))
        return false;

    TextBox textBox = new TextBox();

    try
    {
        // stringToCheck == ""; // !!! does NOT throw !!!
        // stringToCheck == "Name$"; // throws
        // stringToCheck == "0"; // throws
        // stringToCheck == "name with blank"; // throws
        // stringToCheck == "public"; // does NOT throw
        // stringToCheck == "ValidName";

        textBox.Name = stringToCheck;
    }
    catch (ArgumentException ex)
    {
        return false;
    }

    return true;
}
