address1_latitude和address1_longitude不是從RetrieveMultiple獲取的

Question

嗨，我嘗試使用CRM SDK從CRM中獲取address1_latitude和address1_longitude，這是mu代碼

var querybyattribute11 = new QueryByAttribute("account");
querybyattribute11.ColumnSet = new ColumnSet("name", "address1_city", "statuscode", "address1_postalcode", "address1_latitude", "address1_longitude");
querybyattribute11.Attributes.AddRange("name");
querybyattribute11.Values.AddRange("ASSOCIATED COMBUSTION INC");
EntityCollection entities = service.RetrieveMultiple(querybyattribute11);

foreach (Entity item in entities.Entities)
{

   // Console.WriteLine("Name: {0}. Id: {1}", role.Name, role.Id);
   list += item.Attributes["name"].ToString() + "  " + item.Attributes["address1_longitude"] .ToString() + "\n";
}

但是我沒有得到它item.Attributes["address1_longitude"]錯誤消息是

'The given key was not present in the dictionary.'

Answer 1

可能是因為它為空。

請嘗試以下兩個選項之一：

item["address1_longitude"]  (shouldn't raise exception, it would return null if blank, otherwise the address longitude)

要檢查該列是否存在：

item.Attributes.ContainsKey("address1_longitude")
