C#获取用户角色始终为空。尝试了多种方法，但均无效

我创建了一个Web应用程序，其中包含一个

菜单

。我的目标是，一个名为“

”mgaLVTSekretariat“

的特定用户组无法访问该菜单

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
}

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

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

选择。2:

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

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

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

选择。3:

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

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

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

当我执行程序时，

if语句

从来都不是

true

。读取值时，角色为空。在每个选项中。我试过了

恐怕我的错误在Web.Config中。这就是：

假的
//连接字符串

该菜单包含3个要打开的不同站点：

• StammdatenHalbtax.aspx
• STAMMDATESTATUS.aspx
• Default.aspx

我也尝试在我的Web.Config中阻止这3个站点：

<location path="Default.aspx">
        <system.web>
          <authorization>
            <allow roles="mgaLVTAdministration, mgaLVTSekretariat"/>

            <deny users="?"/>

          </authorization>
        </system.web>
      </location>

两种方法都不行。有什么建议吗？

使用

二进制读取器

将

PostedFile

转换为

字节

数组：

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

---

也许可以帮助您。谢谢您，但我如何在我的项目中实施它@是的，您将代码添加到if语句中。当lehrling.passfoto的值为“”（null）@diiN时，我该怎么办_
