C# dapper 返回Sql server 自增长ID 标识列SCOPE_IDENTITY

SQL获取刚插入的记录的自动增长列ID的值 

CREATE TABLE [dbo].[MesTest](
 [ID] [int] IDENTITY(1,1) NOT NULL,
 [Msg] [nvarchar](500) NULL
) ON [PRIMARY]

 [TestMethod]
        public void TestMethod1()
        {
            var sql = "INSERT INTO [MesTest] ([Msg]) VALUES('ss');SELECT @id=SCOPE_IDENTITY()";
            using (var db = Database.DbService)
            {
                var p = new DynamicParameters();
                p.Add("@ID", dbType: DbType.Int32, direction: ParameterDirection.Output);
                var i = db.Execute(sql,p);
                var i1 = p.Get<int>("@ID");
               
                Assert.Inconclusive(i1.ToString());
            }
        }
