具有指定標識或名稱的資源已存在 - Dcoumentdb

我已經使用documentdb插入了兩個json文檔，並將它們放在名爲Hotelwithroomtype的列表中。我想用一些新值更新已創建的json文檔，然後將它們重新創建爲新文檔。這裏是我的代碼具有指定標識或名稱的資源已存在 - Dcoumentdb

foreach (var item in Hotelwithroomtype) 
      { 
       foreach (var cal in Calendardata) 
       { 

        item.CalendarDate = Convert.ToDateTime(cal.CalendarDate); 
        item.CalendarDay = cal.Calendarday; 
        item.issweekday = Convert.ToBoolean(cal.isweekday); 
        item.issweekend = Convert.ToBoolean(cal.isweekend); 

        foreach (var prop in item.RoomTypes.RoomTypeList) 
        { 

         prop.Mon = "0"; 
         prop.Tue = "0"; 
         prop.Wed = "0"; 
         prop.Thur = "0"; 
         prop.Fri = "0"; 
         prop.Sat = "0"; 
         prop.Sun = "0"; 
         prop.Count = "0"; 
         prop.CountType = "0"; 

        } 
        // var docExists = client.CreateDocumentQuery(UriFactory.CreateDocumentCollectionUri("next", "nextCollection")) 
        //.Where(doc => doc.Id == item.id) 
        //.Select(doc => doc.Id) 
        //.AsEnumerable() 
        //.Any(); 

        await client.CreateDocumentAsync(collectionLink, item); 

       } 


      }

我想使用更新的值當前文檔，但需要他們成爲新document.When我試圖創建我的樣品JSON文檔得到以下錯誤「指定的ID或名稱的資源已經存在」。任何幫助將非常感激。

感謝

正在嘗試，而不是一個新的文檔與id等於現有文檔的id。這是不允許的，所以操作失敗。在插入修改的副本之前，您需要爲其分配新的id。

任何想法如何做到這一點，或者我可以創建一個新的列表，然後將它們添加爲新文檔？或者，如果可能的話，如何禁用自動ID生成，並使用我們的財產之一作爲身份證在上述情況下，我可以使用酒店代碼作爲ID？ – Melvin

@Melvin我猜你的課程已經擁有'id'屬性（我也可以在註釋代碼中看到它 - item.id'）。否則，我會希望你的代碼工作。如果你有'id'，你需要重置它。 'id'也可以是經過計算的屬性，因此您可以在其getter/setter中使用酒店代碼。 – Mikhail

該ID是自動生成的我沒有手動設置它們，所以有什麼選擇，我可以在創建文檔時禁用該自動生成？ – Melvin
