问题描述

有人知道吗?

这是编码产生错误，即"名称" ids"在当前上下文中不存在".

如何解决，在这种情况下，只有字符串pro_id作为QueryString传递，但我希望传递数字.

Can anyone know?

This is the coding produce error that "The name ''ids'' does not exist in the current context".

How to solve, in this only the string pro_id is passed as QueryString but I want number to be passed.

protected void btndetails_Click(object sender, EventArgs e)
{
  string ids="pro_id";
  Response.Redirect("product_details.aspx?ids=" + ids);
}

推荐答案

您所引用的变量(ids)在btndetails_Click过程中不存在.这个价值是从哪里来的?修复该问题，它将对其进行排序.

You are referencing a variable (ids) that doesn''t exist in your btndetails_Click procedure. Where is that value meant to be coming from? Fix that and it will be sorted.

string ids="";
protected void btndetails_Click(object sender, EventArgs e)
{
Response.Redirect("product_details.aspx?ids=" + ids);
}

您必须为ids变量分配值.

You have to assign the value for ids variable..

请确保已定义ID，并且Button_click事件&有一些价值.
