Question

我有一个CRM插件，可以触发表单上某个字段的更新，然后该插件应该利用SDK的导入功能将CSV记录导入Dynamics，我收到了以下错误

请求类型的许可 'System.Security.Permissions.FileIOPermission，mscorlib， Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089' 失败。

我已将插入隔离模式的插件设置为NONE，而不是Sandbox，但我仍然收到错误，任何想法为什么会发生这种情况以及我如何解决它。它在ImportFile部分失败，该部分封装在ImportData函数中。

请参阅下面的插件代码

public void Execute(IServiceProvider serviceProvider)
    {
        ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
        IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

        if (context == null)
        {
            throw new ArgumentNullException("loaclContext");
        }

        if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
        {
            Entity supplyClaimsEntity = (Entity)context.InputParameters["Target"];

            if (supplyClaimsEntity.LogicalName != "new_supplierclaimsupdate")
            {
                return;
            }

            IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));

            IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);

            string entityBeginUpload = "Start Upload";
            try
            {

                string filePath = (@"C:\Team CRM\Warp.csv");

                ImportData(service, new_topproducts.EntityLogicalName, filePath);

            }

            catch (FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> ex)
            {
                Console.WriteLine("The application terminated with an error.");

                    null == ex.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
            }

                Console.WriteLine(ex.Message);

                // Display the details of the inner exception.
                if (ex.InnerException != null)
                {
                    Console.WriteLine(ex.InnerException.Message);

                    FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> fe = ex.InnerException
                        as FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault>;
                    if (fe != null)
                    {
                        Console.WriteLine("Timestamp: {0}", fe.Detail.Timestamp);
                        Console.WriteLine("Code: {0}", fe.Detail.ErrorCode);
                        Console.WriteLine("Message: {0}", fe.Detail.Message);
                        Console.WriteLine("Trace: {0}", fe.Detail.TraceText);
                        Console.WriteLine("Inner Fault: {0}",
                            null == fe.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
                    }
                }
            }

假设这是同步（异步可能在不同的服务器上运行，具体取决于您的部署）插件，请检查用户正在运行的IIS帐户是否具有该文件夹的权限。如果没有，那么您将收到您所看到的文件权限错误。

Answer 2

您是否在在线组织上运行该插件？在这种情况下，您无法在注册程序集时将组织设置为模式。
