Just to add-on, If you're not passing all the parameters, then optional parameters can be passed only after the required parameters.
Instead of posting it here in Q/A forum, you should post it as a blog.

C# 4.0 has introduced optional parameters for functions and constructors.
Their values don't have to be explicitly specified by the caller. If the parameter has not been specified as an argument by the caller it is given a default value
voidDisplayOutput(string text1, string text2="optional parameter"){Print(text1); Print(text2);}Only last parameter is optional parameter
