在lambda表達式C＃動態生成雙引號字符串

Question

我有數字，我在列表中concatenating double quoted動態添加和投入的代碼如下

ArrayList arrRespId = new ArrayList(); 
for (int i = 0; i < hitsCountRespId; i++) 
{ 
    arrRespId.Add("\"" + jsonRespId["aggregations"]["my_fields"]["buckets"][i]["key"].ToString() + "\""); 
} //Adding all numbers in the list with double quoted 

var strDouble = string.Join(",", arrRespId.ToArray()); //"5","6","7" 

嗨我有lambda expression守則，獲取信息從Elasticsearch

var SearchAggregate = client.Search<string>(sd => sd 
        .Index("Index") 
        .Type("Table") 
        .Size(0) 
        .Query(q => q 
         .Bool(b => b 
          .Must(
           m => m.Terms("QID", new[] { strDouble.tostring() }), 
           m => m.Terms("ProjectID", new[] { "50" }), 
           m => m.Terms("RespID", new[] { abc.ToString() }) 
           //m => m.Terms("RespID", new[] { "1","2" }) 
           ))))); 

，但問題是，當我把那個雙引號字符串中的lambda表達式它採取"\"5\",\"6\",\"7\",....和我的代碼不返回任何

我會感謝您的幫助！謝謝

我看見你的代碼和圖像輸出你理解究竟是什麼term在lambda表達式期待做的錯誤，它不希望用雙引號數字或字符
term期待包含字符串數組所需數量，代碼應該如下

string[] arrRespId= new arrRespId[50]; //in your scenario you can put `hitsCountRespId` as array size 
for (int i = 0; i < hitsCountRespId; i++) 
{ 
    arrRespId[i]= jsonRespId["aggregations"]["my_fields"]["buckets"][i]["key"].ToString(); 
} 

，然後只把那string array在你的Lambda表達式如下

var SearchAggregate = client.Search<string>(sd => sd 
        .Index("Index") 
        .Type("Table") 
        .Size(0) 
        .Query(q => q 
         .Bool(b => b 
          .Must(
           m => m.Terms("QID", new[] { strDouble.tostring() }), 
           m => m.Terms("ProjectID", new[] { "50" }), 
           m => m.Terms("RespID", arrRespId)          
           ))))); 

我希望它能爲你工作。
