Note that if the optional parameters are System.Objects (VARIANTs), or if you're willing to do a late-bound call, you can just pass Type.Missing for each optional parameter instead of figuring out and passing the default value for each one.

Default parameters are not supported in C#. This was done for a couple of reasons. However, the main reason is for versioning. Per Joe Nalewabau (Product Manager for C#) "Default parameters were not added due to the versioning issues associated with them. Essentially when you add default parameters the compiler essentially burns the default value in to the callers code when the code is compiled. This means that if you change the default values all clients must be recompiled to take advantage of the new value - rather than have the class library itself decide what the default values should be." You could write a wrapper method that only takes the params you would normally change and calls the wrapped method with the default params.

In VB you can just leave those parameters out, but in C# it seems that you have to give values for every parameter, meaning that you need to figure out what each default value is (somehow!). Is this correct? Thanks, Kirk You can read messages from the DOTNET archive, unsubscribe from DOTNET, or subscribe to other DevelopMentor lists at http://discuss.develop.com.
