Object - ToNullableUInt32OrDefault

An object extension method that converts this object to a nullable u int 32 or default.

Try it

public static void Main()
{
	object val1 = 123;
    object val2 = "1090";
	object thisNull = null;
	object thisInvalid = "A100";
	
	string format = "{0, -20} {1, -15}";
	
	Console.WriteLine(format, "Object", "ToNullableUInt32OrDefault");
	Console.WriteLine(format, "------", "-------------------------");
	
	// C# Extension Method: Object - ToNullableUInt32OrDefault
	Console.WriteLine(format, val1, val1.ToNullableUInt32OrDefault());
	Console.WriteLine(format, val2, val2.ToNullableUInt32OrDefault());
	Console.WriteLine(format, "null", thisNull.ToNullableUInt32OrDefault());
	Console.WriteLine(format, thisInvalid, thisInvalid.ToNullableUInt32OrDefault());
	Console.WriteLine(format, thisInvalid, thisInvalid.ToNullableUInt32OrDefault(1));
	Console.WriteLine(format, thisInvalid, thisInvalid.ToNullableUInt32OrDefault(() => 2));
