[renji53521]

我要写三个 click 事件，来显示三个信息，用 GetUserName(); 显示错误。应该怎么写才适合XP，VISTA 和WIN7系统显示这三个系统用户信息。。代码如下。。我应该怎样写？

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace CC
{
public partial class Home : Form
{
public Home()
{
InitializeComponent();
}

private void pictureBox1_Click(object sender, EventArgs e)
{
//show user account picture
}

private void label1_Click(object sender, EventArgs e)
{
//show user account Name
}

private void label2_Click(object sender, EventArgs e)
{
// show user account Type
}
}
}

没看明白

就是你按电脑的“开始”菜单的时候，你会看到一个小图片，还有当前的用户名，和该用户的类型，即是系统管理员，还是超级用户，我现在想在窗口的 pictureBox1显示那个小图片，label1直接显示用户名，label2显示该用户的类型。

1.获得当前用户名：

using System.Management;

                SelectQuery query = new SelectQuery("select * from Win32_UserAccount where Name='" + System.Environment.UserName + "'");
                ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
                foreach (ManagementObject envVar in searcher.Get())
                {
                    string fullName = envVar["FullName"].ToString();
                }

2。获得当前用户权限（参考了 http://pcheruku.wordpress.com/2008/07/31/sample-c-code-to-get-user-login-type/)

using System.Security.Principal;

WindowsIdentity ident = WindowsIdentity.GetCurrent();
WindowsPrincipal principal = new WindowsPrincipal(ident);

string userType = "";
if (principal.IsInRole(WindowsBuiltInRole.Administrator))
{
    userType = "Administrator";
}
else if (principal.IsInRole(WindowsBuiltInRole.PowerUser))
{
    userType = "Power User";
}
else if (principal.IsInRole(WindowsBuiltInRole.User))
{
    userType = "User";
}
else if (principal.IsInRole(WindowsBuiltInRole.Guest))
{
    userType = "Guest";
}

3.获取用户图片，参考http://go4answers.webhost4life.com/Example/get-windows-user-account-name-picture-77793.aspx

如果是数据访问的话建议楼主看看三层架构的类库设计
