listview的ItemDataBound事件进行数据绑定时,出现未处理的“System.StackOverflowException”类型的异常
C# code
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
    {
        ListViewDataItem dataItem = (ListViewDataItem)e.Item;

        int index = dataItem.DisplayIndex;

        DataSet ds = new DataSet();
        ds.ReadXml(Server.MapPath("msg.xml"));//未处理的“System.StackOverflowException”类型的异常出现在 mscorlib.dll
        
        rowdata = ds.Tables[0].Rows[index]["staff"].ToString();
        if (rowdata.Length > 0)
        {
            int length = rowdata.Length - 1;
            rowdata = rowdata.Substring(0, length);

            //HyperLink hyperlink1 = (HyperLink)e.Item.FindControl("HyperLink1");
            //HyperLink hyperlink1 = new HyperLink();
            Panel panel = (Panel)dataItem.FindControl("panel1");
            string[] files = rowdata.Split('#');
            int L = files.Length;
            for (int i = 0; i < L; i++)
            {
                string[] filename = files[i].Split('@');
                //Response.Write(filename[0]);
                HyperLink hyperlink1 = new HyperLink();
                hyperlink1.NavigateUrl = "usersUpload/" + filename[0];
                //Response.Write(filename[0]);
                hyperlink1.Text = "<img alt='附件:'src='image/zip.jpg' style='border:0px;' />  " + filename[0] + "<br/>";
                hyperlink1.ID = "file";
                panel.Controls.Add(hyperlink1);
                //hyperlink1.Text = hyperlink1.Text+ filename[0] ;

            }
            //Response.Write(files[3]);
            //hyperlink1.Text = test;
        }
        bindGrid();

    }
public void bindGrid()
    {
        DataSet ds = new DataSet();

        ds.ReadXml(Server.MapPath("msg.xml"));
        
        if (ds.Tables.Count != 0)
        {
            
            ListView1.DataSource = ds.Tables[0];
            ListView1.DataBind();
            ds.Dispose();
            Label1.Visible = false;
        }
        else
        {
            Label1.Visible = true;
        }
    }


这段代码在vs2010里运行没问题,在vs2008里会出现“未处理的“System.StackOverflowException”类型的异常出现在 mscorlib.dll”的异常,求师傅们看看这段代码哪里有问题

------解决方案--------------------
bindGrid中对listview进行了绑定,而你在 ListView1_ItemDataBound又调用bindGrid,继而又会触发 ListView1_ItemDataBound,造成死循环
