Make a Messagebox display a variable

Question

I want a MessageBox to display an int variable, can anybody help?

Answer 1

You want to use the MessageBox.Show() method

int num = 0;
MessageBox.Show(num.ToString());

Answer 2

Use string formatting with the message box:

int courseId = 0;

DialogResult result = MessageBox.Show(string.Format("Print Course No {0} ?", courseId), "Print Confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

Answer 3

jb's answer is correct, if you need some more information MSDN has full documentation at: http://msdn.microsoft.com/en-us/library/aa984357(v=vs.71).aspx

For simple library matters, MSDN nearly always has excellent, easy to understand documentation.

Answer 4

This is really easy. Don't get confused and write int test = 1;, then MessageBox.Show("test:" + 1), because then if test's value changes, that will just print 1 instead of test's new value 2.

Example:

int test = 1;
test = test + 1;
MessageBox.Show(test);

Answer 5

It is quite easy to achieve this, see this example:

int a=1;
MessageBox.Show(a+"");

Answer 6

Here: int test = 0; messagebox.show(Convert.ToString(test));
