Dynamics crm 处理动态CRM自定义工作流，该工作流更新；修改为；字段--需要调试帮助吗
我正在开发一个Dynamics CRM CWA，它根据名为“准备人”的文本字段更新“修改人”字段。我目前有3个错误，我需要一些帮助调试（见下文）。它们可能很容易修复，但我对编码相当陌生。如有任何帮助，我们将不胜感激。谢谢Dynamics crm 处理动态CRM自定义工作流，该工作流更新；修改为；字段--需要调试帮助吗,dynamics-crm,workflow,Dynamics Crm,Workflow,我正在开发一个Dynamics CRM CWA，它根据名为“准备人”的文本字段更新“修改人”字段。我目前有3个错误，我需要一些帮助调试（见下文）。它们可能很容易修复，但我对编码相当陌生。如有任何帮助，我们将不胜感激。谢谢 using System; using System.Collections.Generic; using System.Collections.ObjectModel; using System.Globalization; using System.Linq; using

以下是对您的问题的一些反馈： 错误1-“CodeActivityContext”不包含“CreateQuery”的定义
此问题与以下几行有关：
var _contact = activityContext.CreateQuery("contact").Where(c => c.GetAttributeValue<Guid>("contactid").Equals(contactid)).FirstOrDefault();
var query = new QueryExpression("systemuser"):
query.Criteria.AddCondition("fullname", ConditionOperator.Equal, fullname);
var _user = orgService.RetrieveMultiple(query).Entities.FirstOrDefault();
这是基本的C#，在使用变量之前必须实例化它：
string fullname;
讽刺和真实。这应该是activityContext，但我们已经在为错误1所做的更改中修复了此问题
Entity _user = context.CreateQuery("systemuser").Where(e => e.GetAttributeValue<string>("fullname").Equals(fullname)).FirstOrDefault();
Entity\u user=context.CreateQuery（“系统用户”）.Where（e=>e.GetAttributeValue（“全名”）.Equals（全名））.FirstOrDefault（）；
string fullname;
Entity _user = context.CreateQuery("systemuser").Where(e => e.GetAttributeValue<string>("fullname").Equals(fullname)).FirstOrDefault();
