c# - ASP.Net 在“UserPrincipal user = UserPrincipal.FindByIdentity(ctx, User.Identity.Name);”上出现错误
问题描述
我正在尝试部署一个 ASP.net webapp - 我最初运行的是以下代码：
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
UserPrincipal user = UserPrincipal.Current;
string displayName = user.DisplayName;
string username = user.SamAccountName;
但我收到以下错误：
无法将“System.DirectoryServices.AccountManagement.GroupPrincipal”类型的对象转换为“System.DirectoryServices.AccountManagement.UserPrincipal”类型。
正如其他帖子中所建议的那样，在 IIS 中，我将授权更改为 Windows 授权并将我的代码更改为：
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, User.Identity.Name);
但是，Identity 一词带有红色下划线，错误显示为：
“SqlDataSource”不包含“Identity”的定义，并且找不到接受“SqlDataSource”类型的第一个参数的可访问扩展方法“Identity”（您是否缺少 using 指令或程序集引用？）
有谁知道我该如何解决这个问题？
完整的cs代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Configuration;
using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;
using System.Data;
using System.IO;
namespace Assets
{
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, User.Identity.Name);
if ((dgUser.Rows.Count == 0) || (dgUser.Rows[0].Cells[3].Text == "0"))
{
Response.Redirect("AccessDenied.aspx");
}
else
{
string admin = dgUser.Rows[0].Cells[4].Text;
if (admin.ToString() == "1")
{
sidebarConfig.Visible = true;
}
else
{
sidebarConfig.Visible = false;
}
}
}
protected void gvUser_SelectedIndexChanged(object sender, EventArgs e)
{
}
protected void users_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
}
}
}
