Object - ToBooleanOrDefault

An object extension method that converts this object to a boolean or default.

Try it

public static void Main()
{
	object thisValid = true;
    object thisInvalid = "FizzBuzz";
	
	string format = "{0, -20} {1, -15}";
	
	Console.WriteLine(format, "Object", "ToBooleanOrDefault");
	Console.WriteLine(format, "------", "------------------");
	
	// C# Extension Method: Object - ToBooleanOrDefault
	Console.WriteLine(format, thisValid, thisValid.ToBooleanOrDefault());
	Console.WriteLine(format, thisInvalid, thisInvalid.ToBooleanOrDefault());
	Console.WriteLine(format, thisInvalid, thisInvalid.ToBooleanOrDefault(false));
	Console.WriteLine(format, thisInvalid, thisInvalid.ToBooleanOrDefault(() => false));
