C#获取用户角色始终为空.尝试了多种方法，都没有成功

本文关键字：方法 成功 角色 用户 获取 | 更新日期: 2023-09-27 18:00:12

我创建了一个包含menu的WebApplication。我的目标是某个名为"mgaLVTSekretariat"的用户组无法访问菜单。

我正在使用ASP。Net、C#和EF6。

我尝试了以下方法：

选择。1:

if (Roles.IsUserInRole(User.Identity.Name, "mgaLVTSekretariat"))
{
     //my code to block the menu
}

选择。2:

if (User.IsInRole("mgaLVTSekretariat"))
{
     //my code to block the menu
}

选择。3:

if (RolePrincipal.Current.IsInRole("mgaLVTAdministration"))
{
     //my code to block the menu
}

当我执行程序时，if-statement永远不是true。当我读出该值时，该角色为空。在每个Opt。我试过了。

恐怕我的错误在我的网上。配置。现在是：

<?xml version="1.0"?>

菜单包含3个不同的打开站点：

  • StammdatenHalbtax.aspx
  • StammdatenStatus.aspx
  • 默认.aspx

我试图在我的网站上屏蔽这3个网站。配置也：

<location path="Default.aspx">
        <system.web>
          <authorization>
            <allow roles="mgaLVTAdministration, mgaLVTSekretariat"/>
            <deny users="?"/>
          </authorization>
        </system.web>
       </location>
<location path="StammdatenHalbtax.aspx">
        <system.web>
          <authorization>
            <allow roles="mgaLVTSekretariat"/>
            <deny users="?"/>
          </authorization>
        </system.web>
      </location>
  <location path="StammdatenStatus.aspx">
        <system.web>
          <authorization>
            <allow roles="mgaLVTSekretariat"/>
            <deny users="?"/>
          </authorization>
        </system.web>
      </location>

两种方法都不起作用。有什么建议吗？

使用BinaryReader将PostedFile转换为byte数组：

HttpPostedFile file = FileUploadPassfoto.PostedFile;
using (BinaryReader binaryReader = new BinaryReader(file.InputStream))
{
    lehrling.passfoto = binaryReader.ReadBytes(file.ContentLength);
}
