protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
Hero h = new Hero(100);
h._HeroName = "super man <br>";
Response.Write(h._HeroName);
}
protected void Button2_Click(object sender, EventArgs e)
{
h._HeroName = "New Name";
Response.Write(h._HeroName);
}
为什么在Button2_Click中会报 当前上下文不存在 “h”，该怎么改啊，请大侠赐教啊。
