Dapper use Table Value Parameter in C# (Sql Server 数组参数)

Dapper 也可以使用数组参数

参考:Blog on Github

Dapper 调用存储过程：单个参数

  static void Main(string[] args){var connection = new SqlConnection("Data Source=.;Initial Catalog=Datamip;Integrated Security=True;MultipleActiveResultSets=True");var info = connection.Query<Users>("sp_GetUsers", new { id = 5 },commandType: CommandType.StoredProcedure);}

Dapper 调用存储过程：数组参数

需要使用 Sql Server 的自定义类型： dbo.IDList

CREATE TYPE dbo.IDList
AS TABLE
(ID INT
);
GO

c# code

  public static List<WorkLog> QueryWithTVP(){int[] idList = new int[] { 1, 2 };var results = new List<WorkLog>();try{var typeIdsParameter = new List<SqlDataRecord>();// TypeID  数组参数对应的字段var myMetaData = new SqlMetaData[] { new SqlMetaData("TypeID", SqlDbType.Int) };foreach (var num in idList){// Create a new record, i.e. row.var record = new SqlDataRecord(myMetaData);// Set the 1st colunm, i.e., position 0 with the correcponding value:record.SetInt32(0, num);// Add the new row to the table rows array:typeIdsParameter.Add(record);}using (IDbConnection conn = new SqlConnection(DBConfig.ConnectionString)){conn.Open();//调用存储过程，IDList： 自定义类型results =  conn.Query<WorkLog>("dbo.GetWorkLog_ByTypeIds",new TableValueParameter("@TypeIds", "IDList", typeIdsParameter), commandType: CommandType.StoredProcedure).ToList();}}catch (Exception){throw;}return results;}
