c# - 如何将“System.__ComObject”类型转换为记录集或数据集？

Answer 1

上述方法是正确的。它需要更多代码来遍历记录集以填充数据表对象。

public DataTable CallModule()
    {
        try{
        Microsoft.Office.Interop.Access.Application oAccess = new Microsoft.Office.Interop.Access.Application();
        oAccess.Visible = false;
        oAccess.OpenCurrentDatabase(DataBase, false);
        dao.Recordset oRecordSet = oAccess.Run("fReturnRecordset");

        oRecordSet.OpenRecordset();

       //------------------------------------
        DataTable dt = new DataTable();
        dt.Columns.Add("OriginalName");
        dt.Columns.Add("ModifiedName");

        while (!oRecordSet.EOF )
        {
            DataRow dr = dt.NewRow();
            dr["OriginalName"] = Convert.ToString(oRecordSet.Fields[0].Value);
            dr["ModifiedName"] = Convert.ToString(oRecordSet.Fields[1].Value);
            dt.Rows.Add(dr);

            oRecordSet.MoveNext();
        }

        oRecordSet.Close();

        oAccess.DoCmd.Quit(AcQuitOption.acQuitSaveNone);

        oAccess = null;

        return dt;
        }
        catch (Exception ex)
        {
            throw;
        }
    }
