Question

我有一个Azure功能，负责连接到Azure AD并检索一些Azure AD信息。

当我在.Expand()上使用.Users属性时，收到以下编译错误：

   activeDirectoryClient.Users.Expand(x => x.MemberOf).ExecuteAsync().Result;

    (38,17): error CS0012: The type 'Expression<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Linq.Expressions

我已正确添加名称空间，并尝试将其添加到project.json：

中

{
"frameworks": {
"net46":{
  "dependencies": {
    "Microsoft.IdentityModel.Clients.ActiveDirectory": "3.13.5",
    "Microsoft.Azure.ActiveDirectory.GraphClient": "2.1.0",
    "System.Linq": "4.0.0",
    "System.Linq.Expressions": "4.0.0"
   }
  }
 }
}

使用C＃在Azure Functions解决方案中是否存在Linq.Expressions的已知问题？

Answer 1

Azure功能中的Linq.Expressions没有问题。

使用Linq.Expression：

的HttpTriggerCSSharp的工作示例

project.json

{
"frameworks": {
"net46":{
  "dependencies": {
    "Microsoft.IdentityModel.Clients.ActiveDirectory": "3.13.5",
    "Microsoft.Azure.ActiveDirectory.GraphClient": "2.1.0"
   }
  }
 }
}

run.csx

#r "System.Linq.Expressions"

using System.Net;
using Microsoft.Azure.ActiveDirectory.GraphClient;
using Microsoft.IdentityModel.Clients.ActiveDirectory;

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
    log.Info("C# HTTP trigger function processed a request.");

    ActiveDirectoryClient activeDirectoryClient = new ActiveDirectoryClient(new Uri("https://graph.windows.net/" + "testdomain"),
                                                                                async () => await AcquireTokenAsyncForApplication());
    IUser user = activeDirectoryClient.Users.Where(u => u.UserPrincipalName == "admin@testdomain.onmicrosoft.com").ExecuteSingleAsync().Result;

    return req.CreateResponse(HttpStatusCode.OK, "Hello");

}

public static async Task<string> AcquireTokenAsyncForApplication()
{
    return "test";
}

Azure函数：C＃使用System.Linq.Expressions编译错误
