Simple Message Box:

Write MessageBox.Show("Text") in any control code (Button etc.) and write your message like:

  MessageBox.Show("Welcome to Simple MessageBox", "Simple", 

  MessageBoxButtons.OK, MessageBoxIcon.Information);

Conditional message box is same like a simple but with the difference of writing the code and write your code like:

1. Write your condition in message text.
2. Add any Message Box Button you want (Ok, Ok/Cancel, Yes/No, Yes/No/Cancel, etc.)
3. Write the following code to present conditional message box in the control code: 

private void Conditional_button_Click(object sender, EventArgs e)

{

DialogResult = MessageBox.Show("Welcome to Conditional MessageBox \n

Please select one option Yes/No)", 

"Conditional", MessageBoxButtons.YesNo, 

MessageBoxIcon.Information);

if (DialogResult == DialogResult.Yes)
  {
   // any function
  }
  else
  {
   // any function
  }

}
