c#.net SQL存储过程直接传表；用户定义表类型的表

方法一

DataSet dataset = new DataSet();
using (SqlConnection conn = new SqlConnection(SqlHelper.sqlconnectionString2))
{
    conn.Open();
    using (SqlCommand cmd = new SqlCommand("[dbo].[Proc_Save_OrdersPayWxNotify]"))
    {
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Connection = conn;
        cmd.Parameters.AddWithValue("@P0", dt);
        cmd.Parameters.AddWithValue("@P1", UserType);
        using (SqlDataAdapter adp = new SqlDataAdapter(cmd))
        {
            adp.Fill(dataset);

            var ds = dataset;
        }
    }
}

如果上面代码看不懂，可以结合下面文章看

方法二

int UserType=1;
Conversion<DBUserInfoModel> helper = new Conversion<DBUserInfoModel>();
List<DBUserInfoModel> Modellist = new List<DBUserInfoModel>();
Modellist.Add(model);//model 你的数据模型实体变量参数
DataTable dt = helper.FillDataTable(Modellist);//将实体转换成DataTabl类型

SqlParameter[] parm = new SqlParameter[1];
parm[0] = new SqlParameter("@userType ", dt); 

var re = ExecuteDataSet(
    connectionString: SqlHelper.sqlconnectionString2,//数据库连接字符串
    cmdType: CommandType.StoredProcedure,//表示是存储过程
    cmdText: "InsertUserInfo ",//存储过程名称
    commandParameters: parm //参数
    );

上面代码用到的方法

        /// return a dataset
        /// </summary>

        /// <returns>return a dataset</returns>
        public static DataSet ExecuteDataSet(string connectionString, CommandType cmdType, string cmdText, params SqlParameter[] commandParameters)
        {
            SqlConnection conn = new SqlConnection(connectionString);
            SqlCommand cmd = new SqlCommand();
            try
            {
                PrepareCommand(cmd, conn, null, cmdType, cmdText, commandParameters);
                SqlDataAdapter da = new SqlDataAdapter();
                DataSet ds = new DataSet();
                da.SelectCommand = cmd;
                da.Fill(ds);
                conn.Close();  //记得要加上 关闭数据库连接,不然就容易出现超过最大连接池
                return ds;
            }
            catch
            {
                conn.Close();
                throw;
            }
        }

        private static void PrepareCommand(SqlCommand cmd, SqlConnection conn, SqlTransaction trans, CommandType cmdType, string cmdText, SqlParameter[] cmdParms)
        {
            //判断数据库连接状态
            if (conn.State != ConnectionState.Open)
                conn.Open();
            cmd.Connection = conn;
            cmd.CommandTimeout = 1800;
            cmd.CommandText = cmdText;
            //判断是否需要事物处理
            if (trans != null)
                cmd.Transaction = trans;
            cmd.CommandType = cmdType;
            if (cmdParms != null)
            {
                foreach (SqlParameter parm in cmdParms)
                    cmd.Parameters.Add(parm);
            }
        }
