How do I add a number to a label in C#?

So I want to have a number that can be added to but then written out in a label. I'm doing it in Visual C#.NET.

For example, if I had code like this (either in a timer or while loop):

        int i = 0;
        i = i + 5;

        label4 = "Current Number of Views: " + i.ToString开发者_StackOverflow中文版();

I can't use ToString() to convert it to a string. So how would I make i displayable

While I don't understand why you can't use i.toString(), I suppose that you could also use something like

label4.Text = String.Format("Current Number of Views: {0:d}", i);

This should yield the same result.

Edit: as @BiggsTRC points out (which I didn't think of), your error is probably a result of not assigning to the right variable. You probably should access the property label4.Text to assign to. The code example fixes this properly now.

u could use String.Format without explicitly using ToString()

label4.Text = String.Format("Current Number of Views: {0}", i);

This should work. The one issue i see is the label itself. It should look like this:

label4.Text = "Current Number of Views: " + i.ToString();

I dont understand why cant you use i.ToString(). By default, i is assigned with 0 value and hence, i.ToString() would not throw any exception.

if you are using WPF , then you should assign the value to the content property of the label.

label4.Content = "Current Number of Views: " + i.ToString();
