Pass a string to a function

[Sammut]

Hi,

I have the following function to which I need to pass a string variable

private string cMask (string sText)
{

}

but ever time I try to compile I get the error
'test.Form1.cMask(string)': not all code paths return a value

Any idea?
Thanks

Hi,
Since you have specified this function would return a string, make sure it
does so before completion.
For this specific case, the function doesn't return anything.

Hi,

that error message means, that your function with return type "string" does
never return a value, so you have to return a string or use void as return
type for your function.

private string cMask (string sText) {
return "Hello World";
}

--- OR ---

private void cMask (string sText) {
dowhateveryouwantornothing();
}

Your method now accepts a string argument, and returns back a string as well.
If you don't want to return anything, change the method declaration to this:

private void cMask (string sText)
