C# Graph Beta 在 1 次调用中获取所有 Win32LobApp 的所有分配类型及其检测规则

Question

我尝试通过对 GraphAPI Beta 的 1 次调用来获取所有移动应用程序及其检测规则。使用 PostMan，发送 1 个 GET 请求

https://graph.microsoft.com/beta/deviceAppManagement/mobileApps?$filter=isof('microsoft.graph.win32LobApp')&$top=1000

将返回 JSON 格式的前 100 个移动应用程序列表。每个对象都有一个检测规则，其中包含各种数据，但在使用 Graph Beta 库在 C# 中执行相同操作时情况并非如此（至少据我所知）。

这是我编写的一个方法，用于尝试获取分配 ID、检测规则和createdOn：

public async Task<List<GraphResponseModel>> GetAllWin32LobAppWithDetectionRules()
    {
        try
        {
            
            Win32LobAppRegistryDetection detectionRule = null;
            List<GraphResponseModel> graphResponseModelList = new();
            List<string?> idsFromAssignment = [];

            // Get all Win32LobApps
            var mobileApps = await _graphClient.DeviceAppManagement.MobileApps.GetAsync(context =>
            {
                context.QueryParameters.Filter = "isof('microsoft.graph.win32LobApp')";
                context.QueryParameters.Expand = new string[] {"assignments"};
            });

            foreach (var mobileApp in mobileApps.Value)
            {
                mobileApp.Assignments.ForEach(assignment =>
                {
                    idsFromAssignment.Add(assignment.Id);
                });
                // Cast the mobileApp to a Win32LobApp
                var win32LobApp = (Win32LobApp)mobileApp;
                
                _detectionRulesModel = null;
                
                foreach (var detection in win32LobApp.DetectionRules)
                {
                    if (detection.OdataType == "#microsoft.graph.win32LobAppRegistryDetection")
                    {
                        detectionRule = (Win32LobAppRegistryDetection)detection;
                        _detectionRulesModel = new DetectionRulesModel(detectionRule.OdataType, (bool)detectionRule.Check32BitOn64System, detectionRule.KeyPath, detectionRule.ValueName,detectionRule.DetectionType.Value.ToString(), detectionRule.Operator.ToString(), detectionRule.DetectionValue);
                    }
                    else
                    {
                        continue;
                    }
                    _createdOn = mobileApp.CreatedDateTime.Value.DateTime;
                   
                    graphResponseModelList.Add(new GraphResponseModel(idsFromAssignment, _detectionRulesModel, _createdOn));
                }
            }
            return graphResponseModelList;
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        } 
    }

不幸的是，我收到回复，其中包含包含我拥有的实际软件数量的列表，但仅填充了

_createdOn

字段，其他字段为空。

首先，检查他们是否正确访问检测规则和分配。然后，在循环内将值正确添加到模型中。

代码：

public async Task<List<GraphResponseModel>> GetAllWin32LobAppWithDetectionRules()
{
    try
    {
        List<GraphResponseModel> graphResponseModelList = new List<GraphResponseModel>();

        // Get all Win32LobApps
        var mobileApps = await _graphClient.DeviceAppManagement.MobileApps.GetAsync(context =>
        {
            context.QueryParameters.Filter = "isof('microsoft.graph.win32LobApp')";
            context.QueryParameters.Expand = new string[] { "assignments", "detectionRules" };
        });

        foreach (var mobileApp in mobileApps.Value)
        {
            List<string> assignmentIds = mobileApp.Assignments.Select(assignment => assignment.Id).ToList();
            DateTime createdOn = mobileApp.CreatedDateTime.Value.DateTime;
            List<DetectionRulesModel> detectionRulesModels = new List<DetectionRulesModel>();

            // Check if the mobileApp has detection rules
            if (mobileApp.DetectionRules != null)
            {
                foreach (var detectionRule in mobileApp.DetectionRules)
                {
                    if (detectionRule.ODataType == "#microsoft.graph.win32LobAppRegistryDetection")
                    {
                        var win32LobAppRegistryDetection = (Win32LobAppRegistryDetection)detectionRule;
                        DetectionRulesModel detectionRulesModel = new DetectionRulesModel(
                            detectionRule.ODataType,
                            win32LobAppRegistryDetection.Check32BitOn64System,
                            win32LobAppRegistryDetection.KeyPath,
                            win32LobAppRegistryDetection.ValueName,
                            win32LobAppRegistryDetection.DetectionType?.ToString(),
                            win32LobAppRegistryDetection.Operator?.ToString(),
                            win32LobAppRegistryDetection.DetectionValue
                        );

                        detectionRulesModels.Add(detectionRulesModel);
                    }
                }
            }

            graphResponseModelList.Add(new GraphResponseModel(assignmentIds, detectionRulesModels, createdOn));
        }

        return graphResponseModelList;
    }
    catch (Exception e)
    {
        Console.WriteLine(e);
        throw;
    }
}

• 在上面，我们直接访问

  mobileApp.Assignments

  和

  mobileApp.DetectionRules

  并在循环中正确填充

  DetectionRulesModel

  列表和

  assignmentIds

  列表。

• 然后将填充的模型添加到循环外部的

  graphResponseModelList

  列表中。

下面表示移动应用程序的创建时间。

{
    "assignmentIds": ["assignment1", "assignment2"],
    "detectionRules": {
        "OdataType": "#microsoft.graph.win32LobAppRegistryDetection",
        "Check32BitOn64System": true,
        "KeyPath": "HKEY_LOCAL_MACHINE\\Software\\MyApp",
        "ValueName": "Version",
        "DetectionType": "RegistryValueExists",
        "Operator": "Equals",
        "DetectionValue": "1.0"
    },
    "createdOn": "2024-05-10T15:30:00Z"
}
