错误::无效令牌'='类，结构或接口成员声明 [英] Error ::Invalid token '=' in class, struct, or interface member declaration

问题描述

尝试使用以下code隐藏母版页在我的内容页面板

trying to hide a panel of Master Page in my content page using the following code

 Panel p = this.Master.FindControl("panel1") as Panel;  
 p.Visible = false; //Error is showing on this line

为什么这个错误？

Why this error ?

推荐答案

我怀疑你已经得到了code是这样的：

I suspect you've got the code like this:

class MyPage : Page
{
    Panel p = this.Master.FindControl("panel1") as Panel;  
    p.Visible = false;
}

您不能只是把code类中的那样 - 一切比声明（如字段）其他需要在一个方法：

You can't just put code in the class like that - everything other than declarations (e.g. fields) needs to be in a method:

class MyPage : Page
{
    public void Page_Load(object sender, EventArgs e)
    {
        Panel p = this.Master.FindControl("panel1") as Panel;  
        p.Visible = false;
    }
}
