Question

我正在尝试从CRM安装中提取信息，到目前为止，这对于使用默认字段来说很好。但是我在检索自定义字段时遇到了困难，例如，Contacts有一个名为web_username的自定义字段。

我目前的代码是

        QueryExpression query = new QueryExpression();
        query.EntityName = "contact";
        ColumnSet cols = new ColumnSet();
        cols.Attributes = new string[] { "firstname", "lastname" };
        query.ColumnSet = cols;

        BusinessEntityCollection beReturned = tomService.RetrieveMultiple(query);
        foreach (contact _contact in beReturned.BusinessEntities)
        {
            DataRow dr = dt.NewRow();
            dr["firstname"] = _contact.firstname;
            dr["lastname"] = _contact.lastname;
            dt.Rows.Add(dr);
        }

如何在查询中包含自定义字段？我已经尝试过搜索但没有运气但我可能会错误地搜索，因为我不熟悉CRM术语。

提前干杯！

Answer 1

我已经能够解决这个问题了。如果它对任何人都有用，这就是我所做的。该查询设置如前，除了我已将自定义字段添加到ColumnSet。

cols.Attributes = new string[] { "firstname", "lastname", "new_web_username" };

然后使用RetrieveMultipleResponse和Request并将ReturnDynamicEntities设置为true

        RetrieveMultipleResponse retrived = new RetrieveMultipleResponse();

        RetrieveMultipleRequest retrive = new RetrieveMultipleRequest();
        retrive.Query = query;
        retrive.ReturnDynamicEntities = true;

        retrived = (RetrieveMultipleResponse)tomService.Execute(retrive);

如果我有更好的方法，请继续评论。

修改如果您投射到联系人，请使用原始问题中的示例

contact myContact = (contact)myService.Retrieve(EntityName.contact.ToString(), userID, cols);

然后，您可以访问对象的属性

phone = myContact.telephone1; password = myContact.new_password;

如果您更新了您在CRM中添加的CRM网络参考自定义字段，则可以使用

//这里我提到了另一个功能：

    public List<Entity> GetEntitiesCollection(IOrganizationService service, string entityName, ColumnSet col)
