在Form2中我设计了一个label ，让它接受从Form1传过来的UserName，这样我们在以后的设计中好判断用户的权限的大小。
Form2的代码：
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Data.SqlClient;
namespace login
{
///
/// Form2 的摘要说明。
/// public class Form2 : System.Windows.Forms.Form
{
private string UserName;
private
System.Windows.Forms.Label label1;
///
/// 必需的设计器变量。
/// private
System.ComponentModel.Container components = null;
public Form2()
{
//
// Windows 窗体设计器支持所必需的
//
InitializeComponent();
Form1 myForm = new Form1();
myForm.ShowDialog(this);
//
// TODO: 在 InitializeComponent 调用后添加任何构造函数代码
//
}
///
/// 清理所有正在使用的资源。
/// 【登录框设计怎么做，测试用例及步骤分享？】protected override void Dispose( bool disposing )
{
if( disposing )
{
if(components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
