.NET Forum / Languages / C# / September 2007simple one on out parameters in functions
i have this in a class: public void fn_X(out Int32 j) { j = 5; } i call it by using: reportFunctionsCS rfcs = new reportFunctionsCS(); Int32 j = 0; rfcs.fn_X(j); it always gives me this error: CS1502: The best overloaded method match for 'reportFunctionsCS.fn_X(out int)' has some invalid arguments and i have no idea why, but i'm sure it's simple!!!  Signature(i''ll be asking a lot of these, but I find C# totally way cooler than vb and there''s no go''n back!!!) thanks (as always) kes kes, When you have an "out" parameter, you have to declare out when making the call as well, like so: rfcs.fn_X(out j); Signature- Nicholas Paldino [.NET/C# MVP] - mvp@spam.guard.caspershouse.com >i have this in a class: > public void fn_X(out Int32 j) [quoted text clipped - 10 lines] > int)' has some invalid arguments > and i have no idea why, but i'm sure it's simple!!! thanks! This is one of those "Wayne's World, looking at Alice Cooper moments" "... I was unaware of that..." And in truth i was NOT! Thank you, very much appreciated Signature(i''ll be asking a lot of these, but I find C# totally way cooler than vb and there''s no go''n back!!!) thanks (as always) kes > kes, > [quoted text clipped - 17 lines] > > int)' has some invalid arguments > > and i have no idea why, but i'm sure it's simple!!! Hi, You also have to use the out keyword when you are calling the method, this is intended to be use as an indication for the calling code that the value will be modify inside the method. >i have this in a class: > public void fn_X(out Int32 j) [quoted text clipped - 10 lines] > int)' has some invalid arguments > and i have no idea why, but i'm sure it's simple!!!
