Why can't I write MessageBox.Show ("asdfasdf {0}", i) ;?

Question

int i = 85; 
Console.WriteLine("My intelligence quotient is {0}", i);  // Kosher
MessageBox.Show("My intelligence quotient is {0}", i); // Not Kosher

I find this the most terrible debilitating. Does one work and not the other? What is the source of this behavioral mismatch? The more I think about it, the less I can imagine, and the inability to understand too often turns into arrogance.

Answer 1

Console.Writeline has the following overloads:

• http://msdn.microsoft.com/en-us/library/system.console.writeline.aspx

In particular, an overload that takes a format string and params array .

Here is another method that is very similar:

, MessageBox.Show . , , .

, string.Format:

public void ShowMessageBox(string format, params object[] args)
{
    MessageBox.Show(string.Format(format, args));
}

// ...

ShowMessageBox("You entered: {0}", someValue);
