Object - ToByteOrDefault
An object extension method that converts this object to a byte or default.
public static void Main() { object val1 = true; object val2 = 8; object thisInvalid = "FizzBuzz"; string format = "{0, -20} {1, -15}"; Console.WriteLine(format, "Object", "ToByteOrDefault"); Console.WriteLine(format, "------", "------------------"); // C# Extension Method: Object - ToByteOrDefault Console.WriteLine(format, val1, val1.ToByteOrDefault()); Console.WriteLine(format, val2, val2.ToByteOrDefault()); Console.WriteLine(format, thisInvalid, thisInvalid.ToByteOrDefault()); Console.WriteLine(format, thisInvalid, thisInvalid.ToByteOrDefault(0)); Console.WriteLine(format, thisInvalid, thisInvalid.ToByteOrDefault(() => 0)); }
