Passing by reference

How do I pass arguments by reference...!? I thought that it was default. I tried the following...

Code:

OCMSPage ocmsPage = null;
Distribute(pageType, ocmsPage);
if(ocmsPage != null) 
{
    ocmsPage.Make(pageID);
    Page.Controls.Add(ocmsPage);
}

Don't mind the type (OCMSPage). The method Distribute will do somthing like this (only piece of Distribute)...

Code:

oPage = (main_ascx) Page.LoadControl("controls/main.ascx");
oPage.ID = "ocmsPage";

And this has worked fine before I tried to put it into a seperate method, and works if I return the OCMSPage instead!

Thanks

Jacob.

Sorry! I found the answer myself, and if anybody is interested it goes like this in C#...

In the declaration of the method you shall add the keyword ref infront of the type, and when using the method you shall preceed the variable with the same keyword. The above becomes...

OCMSPage ocmsPage = null;
Distribute(pageType, ref ocmsPage);
if(ocmsPage != null)
{
ocmsPage.Make(pageID);
Page.Controls.Add(ocmsPage);
}

and further the prototype...

private void Distribute(int pageType, ref OCMSPage oPage)

Thanks anyway.

Jacob.
