求助!!!
protected void Page_Load(object sender, EventArgs e){
DataSet ds = GetDataItem("select * from news");
DataRow[] row = ds.Tables[0].Select("id"+Request.QueryString["id"]);
foreach (DataRow rs in row)
{
this.Page.Title = rs["classnew"].ToString();
Label1.Text = rs["classnew"].ToString();
Label2.Text = " " + rs["classnn"].ToString();
}
}
显示错误 错误 1 “GetDataItem”方法没有采用“1”个参数的重载 C:\Documents and Settings\Administrator\桌面\web\showNew.aspx.cs 17 22 C:\...\web\
是什么意思啊???
要怎么改正呢?
