CRM Dynamics插件错误:给定的键不存在于字典中(当我触发PhoneCall创建插件时)

本文关键字：插件 Dynamics 创建 PhoneCall 字典 CRM 于字典 不存在 错误 | 更新日期: 2023-09-27 18:02:07

当我在CRm Dynamics 2015中启动电话创建记录插件时，我得到以下错误，

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

        IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
        IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
        IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

        if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
        {
            Entity entity = (Entity)context.InputParameters["Target"];
            if (context.MessageName == "Create")
            {
                try
                {
                    Entity phoneCall = new Entity("phonecall");
                    Int64 NumberToCall = (Int64)phoneCall.Attributes["new_identity"];
                    Int64 ReceiveCallOn = (Int64)phoneCall.Attributes["new_destination"];
                    var apiKey = phoneCall.Attributes["new_apikey"].ToString();
                    Int64 fId = (Int64)phoneCall.Attributes["new_fid"];
                    Guid phoneResponse = service.Create(phoneCall);
                    BasicHttpBinding binding = new BasicHttpBinding();
                    binding.Name = "BasicHttpBinding_IService1";
                    binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
                    binding.MessageEncoding = WSMessageEncoding.Text;
                    binding.TransferMode = TransferMode.Buffered;
                    binding.UseDefaultWebProxy = true;
                    binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
                    binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
                    binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
                    binding.SendTimeout = new TimeSpan(0, 10, 0);
                    EndpointAddress endPointAddress = new EndpointAddress("http://localhost:62009/Service1.svc");

                    ServiceReference1.Service1Client client = new ServiceReference1.Service1Client(binding, endPointAddress);

                    client.WebCall(NumberToCall, ReceiveCallOn, apiKey, fId);
                }
                catch (FaultException<OrganizationServiceFault> ex)
                {
                    tracingService.Trace("MyPlugin: {0}", ex.ToString());
                    throw;
                }
            }

CRM Dynamics插件错误:给定的键不存在于字典中(当我触发PhoneCall创建插件时)

我相信答案是你的phoneCall记录不包含你所指的字段之一。实际上它不包含任何值。因为你实例化了一个实体的新实例，所以字段值不会凭空出现…我建议删除

行
Entity phoneCall = new Entity("phonecall");

用entity替换phoneCall 

                Int64 NumberToCall = (Int64)phoneCall.Attributes["new_identity"];
                Int64 ReceiveCallOn = (Int64)phoneCall.Attributes["new_destination"];
                var apiKey = phoneCall.Attributes["new_apikey"].ToString();
                Int64 fId = (Int64)phoneCall.Attributes["new_fid"];

不确定为什么要在…之后创建另一个电话。你能解释一下你的场景吗?

我相信您要做的是从正在创建的电话记录中获取属性。如果是这种情况，那么代码应该是这样的:

Int64 NumberToCall = entity.Attributes.Contains("new_identity")?(Int64)entity.Attributes["new_identity"]:0;
Int64 ReceiveCallOn = entity.Attributes.Contains("new_destination")?(Int64)entity.Attributes["new_destination"]:0;
var apiKey = entity.Attributes.Contains("new_apikey")?entity.Attributes["new_apikey"].ToString():0;
Int64 fId = entity.Attributes.Contains("new_fid")?(Int64)entity.Attributes["new_fid"]:0;

我的意思是说，而不是"电话"使用"实体"，你从上下文中分配"目标"。在使用该属性之前，还要尝试检查该属性在实体中是否可用，以避免此类错误。

如果该属性不存在，请用您想要的默认值替换。
