+方法一：

DataTable dt = dataSet.Tables[0];

for(int i = 0 ; i < dt.Rows.Count ; i++)

{

   string strName = dt.Rows[i]["字段名"].ToString();

}

方法二：

foreach(DataRow myRow in myDataSet.Tables["temp"].Rows)

{

      var str = myRow[0].ToString();

}

方法三：

foeach(DataRow dr in dt.Rows)   

{   

     object value = dr["ColumnsName"];   

}

方法四：

DataTable dt=new DataTable();   

foreach(DataRow dr in dt.Rows)   

{

   for(int i=0;i<dt.Columns.Count;i++)

   {

dr[i];

   }   

}

绑定DataTable到Reapter。

if (dtb_xx.Rows.Count > 0)

        {

            rp_xx.DataSource = dtb_xx;

            rp_xx.DataBind();

        }

<asp:Repeater ID="rp_xx" runat="server">

       <ItemTemplate>

            <tr>
