It's telling you that result and &result are not the same thing. However, your public void append(string a, string b, string result) wouldn't do much anyway, since you can't modify function parameters without explicitly specifying.

this is the C# forum, your code does not compile here. :|

While in c++ that would work just fine, C# doesn't let you manage pointers or references directly without declaring a block of code unsafe (it might be worth it for you to look up the unsafe keyword and how to use it) What C# does give you for just this type of thing is another couple of keywords for your parameters, ref and out. Both will allow you to pass the reference to your string so that you can modify it inside the function, but there is one main difference. Using the out keyword you can pass in an uninitialised variable that you expect the function to fill in. The ref keyword will only allow you to pass in variables that have been initialised as it expects the function to use and modify it. So, for this type of thing you can simply use the out keyword;

string result;
append("Ali", "Salim", result);

public void append(string a, string b, out string result)
{
result = a +" "+ b;
}

Now, on a slightly different topic, if you plan on combining a lot of strings you may simply want to use the StringBuilder class, as it is a lot more efficient than simply adding two or more strings together.

Or why not simply return the string like a normal person?

Now you surprise me. :laugh: :laugh:
