我正在尝试为 Microsoft Dynamics CRM 2011 编写自定义工作流作为培训练习。我使用的代码如下，它适用于标准插件，但是当作为自定义工作流的一部分运行时，给了我一个字典错误中不存在的键。任何人都可以发现任何原因吗？我检查了所有正确的实体和字段名称。

谢谢

            // Get the context service.
            IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
            IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();

            // Use the context service to create an instance of IOrganizationService.
            IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);

我的猜测是您的代码正在爆炸： targetCont = (Entity)context.InputParameters["Target"];

我的插件代码在获取数据的方式上一直与我的工作流代码略有不同。

所以尝试添加到您的代码中：

context.PrimaryEntityId

最后，您的代码应如下所示：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Collections.ObjectModel;

using System.Activities;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Workflow;
using Microsoft.Xrm.Sdk.Query;
using Microsoft.Xrm.Sdk.Messages;

using System.Diagnostics;


namespace TestWflow
{

    public class SampleCustomActivity : CodeActivity
    {
        protected override void Execute(CodeActivityContext executionContext)
        {
            //Activity code

            // Get the context service.
            IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>   ();
            IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();

            // Use the context service to create an instance of IOrganizationService.
            IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);

            if (context.Depth == 1)
            {
                Guid contID = context.PrimaryEntityId;
                ColumnSet contCols = new ColumnSet("jobtitle");

                var entity = service.Retrieve("contact", contID, contCols);

                entity.Attributes["jobtitle"] = "test jobtitle here";
                service.Update(entity);


            }



        }



    }
