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?
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;
