推荐答案

分离现有的事件处理程序:
button.Click-= Button1_click;
然后分配新的事件处理程序:
按钮.单击+ = btnclick;

如果这不起作用，则意味着您正在标记中分配事件处理程序.删除该代码，并在代码后面进行分配(可以通过(IsPostBack)检查)，然后放入上面的代码.试试这个，让我知道.

Detach the existing event handler:
button.Click -= Button1_click;
then assign the new event handler:
button.Click += btnclick;

If this is not working that means you are assigning the event handler in your markup. Remove that and do the assignment in code-behind maybe with a (IsPostBack) check, and then put the above piece of code. Try this and let me know.

尝试这个

公共局部类_Default:System.Web.UI.Page
{
受保护的void Page_Load(对象发送者，EventArgs e)
{
Button1.Click-= Button1_Click;
Button1.Click + = btnclick;
}
受保护的无效btnclick(对象发送者，EventArgs e)
{
Label1.Text =工作"；
}
}

Try to this

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Button1.Click -= Button1_Click;
Button1.Click += btnclick;
}
protected void btnclick(object sender, EventArgs e)
{
Label1.Text = "worked";
}
}
