ASP.NET Core中的数据表类

Question

If you have tried to use SQLClient in asp.net core, you might have noticed the absence of the DataTables and DataSets, tables structures used to I/O of database.

For output data we have the option of SqlDataReader. But for the input data, I'm yet to find a solution to this problem -eg if you want pass a table to SP by parameter in framework 461, we use 'SqlDbType = SqlDbType.Structured and DataTable class'. Any ideas anyone?

Library that I use: https://github.com/XML-Travelgate/xtg-data-sqlclient

Solution:

        List<SqlDataRecord> datatable = new List<SqlDataRecord>();
        SqlMetaData[] sqlMetaData = new SqlMetaData[2];
        sqlMetaData[0] = new SqlMetaData("id", SqlDbType.Int);
        sqlMetaData[1] = new SqlMetaData("name", SqlDbType.VarChar, 50);
        SqlDataRecord row = new SqlDataRecord(sqlMetaData);
        row.SetValues(new object[] { 1, "John" });
        datatable.Add(row);
        row = new SqlDataRecord(sqlMetaData);
        row.SetValues(new object[] { 2, "Peter" });
        datatable.Add(row);

        var task = dbBase.ExecProcedureDataTableWithParamsAsync<object>("VIEWTABLE", new List<SqlParameter>()
            {
                new SqlParameter()
                {
                     ParameterName = "@paramtable",
                     SqlDbType = SqlDbType.Structured,
                     Direction = ParameterDirection.Input,
                     Value = datatable
                }
            });

现在可以使用.NET Core 2.0和Visual Studio 2017 Preview 15.3 +来实现DataTable，DataSet等
