全局变量不可以用Request.QueryString?
如题..那么我想用全局变量获取url的参数怎么办啊？
public partial class T1 : System.Web.UI.Page
{
public string a = Request.QueryString[ "a "]
protected void Page_Load(object sender, EventArgs e)
{
}
}
这样是报错的

public string a;
protected void Page_Load(object sender, EventArgs e)
{
a = Request.QueryString[ "a "];
}
}
