实现效果:
知识运用：
WindowsPrincipal类的IsInRole方法 //确定当前主体是否属于制定的Windows用户组
public virtual bool IsInRole (WindowsBuiltInRole role) //属性为枚举值之一
实现代码:
private void button1_Click(object sender, EventArgs e)
{
AppDomain domain = System.Threading.Thread.GetDomain(); //获取当前域
domain.SetPrincipalPolicy(System.Security.Principal.PrincipalPolicy.WindowsPrincipal);//将操作系统组映射到角色
//获取当前系统组
System.Security.Principal.WindowsPrincipal principal = (System.Security.Principal.WindowsPrincipal)System.Threading.Thread.CurrentPrincipal;
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.User))
label1.Text += "当前用户为普通用户\n";
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.PowerUser))
label1.Text += "当前用户为超级用户\n";
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Administrator))
label1.Text += "当前用户为系统管理员\n";
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.SystemOperator))
label1.Text += "当前用户为系统操作员\n";
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.BackupOperator))
label1.Text += "当前用户为备份操作员\n";
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.PrintOperator))
label1.Text += "当前用户为打印操作员\n";
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Replicator))
label1.Text += "当前用户为复制操作员\n";
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.AccountOperator))
label1.Text += "当前用户为账户操作员\n";
if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Guest))
label1.Text += "当前用户为来宾用户\n";
}
