c# 弹出带返回值的对话框

1.返回字符串

winform：

屏幕宽度：Screen.PrimaryScreen.Bounds.Width;

屏幕高度：Screen.PrimaryScreen.Bounds.Height;

using Microsoft.VisualBasic;

String PM = Interaction.InputBox("请输入密码", "输入密码", "", Screen.PrimaryScreen.Bounds.Width / 3, Screen.PrimaryScreen.Bounds.Height / 4);

2.基本的yes/ok

  if  (MessageBox.Show( "提示信息" ,  "提示" , MessageBoxButtons.YesNo) == DialogResult.Yes)

  {

        MessageBox.Show( "点了是(Y)" );

  }

  else

  {

        MessageBox.Show( "点了否(N)" );

  }
