{RESOLVED} Function output parameter ... ?

:wave: Hello....

How should i return a value from a function parameter ?

if in old VB version, i use "byref" in declaring a procedure / function parameter.
e.g :

Code:

---

private sub Testing(byval str1 as string, byref str2 as string)
  str2 = str1 & "...just testing"
end sub

private sub command1_click()
  dim tmpStr as string
 
  call Testing("123", tmpstr)
  msgbox(tmpstr)
end sub

---

then the str2 will function as the output parameter.
How should I do that in C# ? and how should i return the value from that output parameter.... ?

Thanks,

The better way would be to have a function that has a return value.

Code:

---

private string Testing(string str1)
{
  return str1 + ".... just testing";
}

You can also use ref keyword to pass value types by reference, but here I would say just use a simple function that returns a value.

Thanks.
I've tried and it works....

you could also use out as followed;

Code:

---

       
        void Button1Click(object sender, EventArgs e)
                {
                        string outPut;
                        this.Test("THIS IS A TEST", out outPut);
                        MessageBox.Show(outPut);
                                 
                }
               
                void Test(string text, out string text2)
                {
                        text2 = text + " Hello";       
                }

---

Hope this helps!!
