Hi
If you are creating component or library, then you have to consider many aspects of
component development. One of the aspects is trying to provide a feature, which is not
supported by the language in which components or library is being created. One of such
thing is creating optional method parameters in C#, Languages like VB.Net natively
supports such kind of parameters. So if you want to create optional method parameters
in C# for VB.Net here is the way out.
<o:p></o:p>
In the namespace System.Runtime.InteropServices there is a one attribute defined,
OptionalAttribute Just apply it to the argument you want to make as optional. That�s
it�
<o:p></o:p>
For example�
<o:p></o:p>
public string GetName([Optional]string param)<o:p></o:p>
{<o:p></o:p>
if (param == null) //Check for null.<o:p></o:p>
param = "Aamir"; //Set the default value.<o:p></o:p>
return param;<o:p></o:p>
}
<o:p></o:p>
Any yes, remember for C# optional parameters are not optional�
