Pass by Ref Textbox.Text

byref, c#

Solution

You can't pass a property by ref, only a field or a variable.

From MSDN :

Properties are not variables. They are actually methods, and therefore cannot be passed as ref parameters.

You have to use an intermediate variable :

string tmp = textBox.Text;
int x = function(1, 2, ref tmp);
textBox.Text = tmp;

Problem

I currently have something that I want to pass a textbox.text by ref. I don't want to pass the whole textbox and I want the function to change the text along with returning the other variable. ``` public int function(int a, int b, string text) { //do something if (a + b > 50) { text = "Omg its bigger than 50!"; } return (a + b); } ``` Is there a way to pass the Textbox.text by ref and change it inside the function?
