Add message to popup message box C# noob question

How can I add message to popup text box:

        catch (Exception)
        {
            Interaction.MsgBox(Conversion.ErrorToString(), MsgBoxStyle.Critical, null);
        }

You can use the MessageBox class.

catch (Exception)
{
    MessageBox.Show(
         Conversion.ErrorToString(),  // Caption
         "Error:",                    // Title displayed
         MessageBoxButtons.OK,        // Only show OK button
         MessageBoxIcon.Error);       // Show error icon (similar to Critical)
}

MessageBox.Show("text", "caption", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation);

Also, I see you tagged the post C#. If you're using C#, don't use anything in the Microsoft.VisualBasic namespace (which is where Interaction lives)

The Microsoft.VisualBasic namespace contains types that support the Visual Basic Runtime in Visual Basic.

You already are, with Conversion.ErrorToString(). If you want a custom message, just pass a string of your choosing as the first argument instead. The third argument (which you have null), can be used to pass a string for the title if you want.
