從C更新CRM查找字段＃

Question

我正在嘗試開發一個應用程序以允許通過gridview更新我們的CRM數據庫。

我所擁有的一切都在努力，直到試圖更新查找字段。試圖查找字段添加到更新它給了我一個錯誤，當

_service = GlobalFunctions.GetServiceAccount(); 
GlobalFunctions.User u = (GlobalFunctions.User)Session["UserInfo"]; 

Entity aspiration = new Entity("tog_aspiration"); 
aspiration.Id = new Guid(inputGridView.DataKeys[e.RowIndex].Value.ToString()); 
aspiration["tog_nofollrl"] = Int32.Parse(tog_nofollrl); 
_service.Update(aspiration); 

現在：

以下是工作的C＃代碼。

_service = GlobalFunctions.GetServiceAccount(); 
GlobalFunctions.User u = (GlobalFunctions.User)Session["UserInfo"]; 

Entity aspiration = new Entity("tog_aspiration"); 
aspiration.Id = new Guid(inputGridView.DataKeys[e.RowIndex].Value.ToString()); 
aspiration["tog_nofollrl"] = Int32.Parse(tog_nofollrl); 
aspiration["tog_techidname"] = new EntityReference("equipment", new Guid(ddlVet.SelectedValue)); 
_service.Update(aspiration); 

以下是錯誤

Answer 1

只是爲了確保，一個名爲tog_techidname或者只是tog_techid查找字段？每個查找都有一個關聯的名稱字段，即查找名稱+「名稱」，但不能直接更新。只需使用EntityReference更新id就足夠了。

嘗試用

aspiration["tog_techid"] = new EntityReference("equipment", new Guid(ddlVet.SelectedValue));
