This is really not a question, but what you are referring to is probably overloading.

If it is not not then please post the relevant code for clarification.

PS. Please read this thread for some posting guidlines

Optional arguments are arguments which are not required.
Really, this shouldn't have required an explanation

C# does not support optional parameters. However 4.0 will support optional parameters. For earlier version, you can either pass, "null" or Type.Missing object as parameters

Expand|Select|Wrap|Line Numbers

 
object o=Type.Missing;

or object o=null;

Expand|Select|Wrap|Line Numbers

 
/For 4.0

public void OptionalParameters(string para, string opPara=" Bytes")

{
 
}

//You can call OptionalParameters either 

OptionalParameters("Hi");

// in this case the opPara=" Bytes" default is assumed
 
OptionaParameters("Hi","Jon");

//here opPara ="Jon", default value is overriden.

You can mimic optional parameters (to an extent) with something like

Expand|Select|Wrap|Line Numbers

 
void myfunction(int required, params object[] OptionalThings)

{

// ....

}
 
//calling both

myfunction(0);

//and

myfunction(1,"fred",23,44,"billy",3.45);

//will work

As a side note, to pass null to int/float/etc types, declare your function with int? value, instead of int value
