MSSQL 2005 C# Assembly & output

Question

I'm having a problem outputting a variable in my assembly.

1. Do I need to add a out string var1 to the parameter list of the function in C#? I get an error - something related to var1 not being set...
2. I tried parameter.Direction = ParameterDirection.Output
3. I can't find any good examples

Edit: My assembly SP currently returns a recordset... I want it to output some variables so that I can use them in another SP where this is called from.

I.E.

DECLARE @var1 int
EXEC dbo.MyAssemblySP @var1 OUTPUT
PRINT @var1

Answer 1

Not quite sure what you are trying to do, but if you are trying to use the out keyword, here is the proper syntax:

public void foo(int arg1, out int arg2) {
    arg2 = arg1;
}

public void foo2() {
    int aOutput;
    foo(1, out aOutput);
    Console.WriteLine(aOutput);
}

Calling foo2 will result in the console writing 1.
