关于在DataTable中删除相关DataRow,急求

Question

现在我需要在DataTable删除我不需要的DataRow
DataTable  里面有4列，我是根据第一列去删除的，比如，如果我要删除，那么就删除第一列是0的所有行 foreach (DataRow drw in dtResult.Rows)
  {
  if (drw[0].ToString() == "0")
   {
     drw.Delete();
   }
    dtResult.AcceptChanges();
  }我现在写了上面的方法，但是执行到第二次就会报错，提示枚举之类的错误。想了很多方法都不稳妥，希望大家帮帮忙，多谢了

Answer 1

                           int[] ar = new int[dtResult.Rows.Count];
                           for (int i = 0; i < dtResult.Rows.Count; i++)
                           {
                                if (dtResult.Rows[i][0].ToString() =="0")
                               {
                               ar[i] = i;
                                }
                           }                           for (int num=ar.Length-1; num > -1 ;num-- )
                           {
                              dtResult.Rows[num].Delete();
                           }可以试试

 DataTable dtResult = new DataTable();            DataColumn dc = new DataColumn() { ColumnName = "ID" };
            dtResult.Columns.Add(dc);            DataRow dr = dtResult.NewRow();
            dr[0] = "0";
            dtResult.Rows.Add(dr);
            dr = dtResult.NewRow();
            dr[0] = "0";
            dtResult.Rows.Add(dr);
            dr = dtResult.NewRow();
            dr[0] = "1";
            dtResult.Rows.Add(dr);
            dr = dtResult.NewRow();
            dr[0] = "1";
            dtResult.Rows.Add(dr);            DataRow drw ;            int j = dtResult.Rows.Count;
            for (int i = 0; i < j; i++)
            {
                drw = dtResult.Rows[0];                if (drw[0].ToString() == "0")
                {
                    drw.Delete();
                }  
            }

 DataTable dtResult = new DataTable();            DataColumn dc = new DataColumn() { ColumnName = "ID" };
            dtResult.Columns.Add(dc);            DataRow dr = dtResult.NewRow();
            dr[0] = "0";
            dtResult.Rows.Add(dr);
            dr = dtResult.NewRow();
            dr[0] = "0";
            dtResult.Rows.Add(dr);
            dr = dtResult.NewRow();
            dr[0] = "1";
            dtResult.Rows.Add(dr);
            dr = dtResult.NewRow();
            dr[0] = "1";
            dtResult.Rows.Add(dr);            DataRow drw ;            int j = dtResult.Rows.Count;
            for (int i = 0; i < j; i++)
            {
                drw = dtResult.Rows[i];                if (drw[0].ToString() == "0")
                {
                    drw.Delete();                    i--;
                    j--;
                }            }
不好意思前面误导大家了，应该是在删完一条数据后，总数据要减1，index数也要-1。
