[Winform] Message.show()问题..
try
  {
  if (MessageBox.Show("您确定要删除吗?", "提示", MessageBoxButtons.YesNo) == DialogResult.No)
  {
  string id = this.UserListView.FocusedItem.Text.ToString();//获取用户点击行焦点
  myUserRule.DeleteUser(id);
  myUserRule.DataListView(this.UserListView, this.txtID.Text.ToString());
  this.txtName.Text = "";
  this.txtPassword.Text = "";
  this.txtEmail.Text = "";
  this.txtAddress.Text = "";
  this.txtCode.Text = "";
  }
   
  }
  catch (Exception)
  {
  MessageBox.Show("请选择要删除的项!","提示");
  }


我点否，还是把数据给删除了，请问我要怎么搞，点否不把数据删除掉呢？
