Problem with formatting a string using String.Format in C #

Question

I need to print a line in a message box in a specific format, for which I use code similar to the one shown below:

string text=""; 
for (int i=0; i<n; i++)
{
   a=..
   b=..
   c=..
   text += String.Format("{0, -8} {1,-4} {2,8}", a, b, c);
}
MessageBox.Show(text);

So, for the following set of values:

XYZ,ABC,100

X,ABC,100

I get the following output:

XYZ     ABC     100

X     ABC     100

So you can see that the second line is poorly formatted. This is probably because I type this in a MessageBox. Space - a symbol and "space" - are different. Any solution for this?

Try using \ttabs to insert between values.

MessageBox, WPF, win32, () , , .

However, you can create your own MessageBox clone using the form and label (and any buttons you need), and then display it using the ShowDialog () method.
