为资源 'User' 的 属性 'mobilePhone' 指定的查询过滤器子句不受支持或无效。在 Azure AD 中通过图形查询访问

Question

我正在尝试从 azure AD 基于某些 属性（移动 phone）访问用户，但出现上述错误 我什至尝试添加 ConcistencyLevel header 和 count = true 查询参数但没有成功 我的代码如下

try
            {
                ClientSecretCredential authProvider = new ClientSecretCredential("*******", "********", "*********");
                List<Option> options = new List<Option>
                {
                    //new QueryOption("count", "true"),
                    //new HeaderOption("ConsistencyLevel","eventual")
                };
                var graphClient = new GraphServiceClient(authProvider);
                var user = await graphClient.Users.Request(options).Filter("mobilePhone eq '1111222223333'").GetAsync();
            }
            catch (Exception ex)
            {

            }

请让我知道我错过了什么

Answer 1

我能够通过在计数参数中添加 $ 来进行过滤

我的工作代码是

try
            {
                ClientSecretCredential authProvider = new ClientSecretCredential("*******", "********", "*********");
                List<Option> options = new List<Option>
                {
                    new QueryOption("$count", "true"),
                    new HeaderOption("ConsistencyLevel","eventual")
                };
                var graphClient = new GraphServiceClient(authProvider);
                var user = await graphClient.Users.Request(options).Filter("mobilePhone eq '1111222223333'").GetAsync();
            }
            catch (Exception ex)
            {

            }
