谁来帮忙解决一下 这个按钮跳转不了

protected void Button1_Click(object sender, EventArgs e)
{
string warehouseId = Request.QueryString["warehouseId"].ToString();
string sql = "select dateline from oms_ebay_class where ebayClassId=" + warehouseId + "";
DataTable dt = ZWL.DBUtility.DbHelperSQL.GetDataTable(sql);

    string tb1 = dt.Rows[0]["ebayClassId"].ToString();
    string sql1 = "updates  oms_ebay_class set ebayClassId =" + tb1 + " where  ebayClassId=" + warehouseId + "";
    ZWL.DBUtility.DbHelperSQL.ExecuteSql(sql1);

    Response.Redirect("Default.aspx");
}

设个断点，调试一下，看有没有发生异常。

像这种自己都不知道错误哪里就别人怎么帮

自己设置个断电看看啊，真不能着急的
