ExecuteStoreQuery和“WHERE IN（{0}）

Question

我收到了以下代码：

string query = "select * from dbo.Personnel where PersonnelId in ({0})";
string param = "1, 2";
var test = model.ExecuteStoreQuery<Personnel>(query, param).ToList();

我收到以下错误：“将nvarchar值'1,2'转换为数据类型int时转换失败。”...

有谁知道如何解决这个问题？我想要的是select * from dbo.Personnel where PersonnelId in (1, 2)，但数字可以是任何数字......

不要向ExecuteStoreQuery发送参数，只需将{0}替换为param

string param = "1, 2";
string query = string.Format("select * from dbo.Personnel where PersonnelId in ({0})", param);

或

string query = "select * from dbo.Personnel where PersonnelId in ({0})";
query = query.Replace("{0}",param);

var test = model.ExecuteStoreQuery<Personnel>(query).ToList();
