Question

我正在尝试开发一个应用程序，允许通过gridview更新我们的CRM数据库。

我所做的一切都在努力，直到尝试更新查阅字段。

以下是C＃代码：

_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);

现在，当尝试将查阅字段添加到更新时，它会给我一个错误。

_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);

这是错误

Incorrect attribute value type System.String

Answer 1

为了确保，查询字段是名为tog_techidname还是只是tog_techid？每个查找都有一个关联的名称字段，即查找名称+“名称”，但您无法直接更新它。仅使用EntityReference更新id就足够了。

尝试

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

从C＃更新CRM查找字段
