c# - 如何让按钮处理 OnClick 事件？

Question

我一直在 ASP.NET 中创建多个自定义控件 - 主要是为了练习和更深入地了解该语言。

我一直在摆弄一个按钮，但我似乎无法让它处理自己的 OnClick 事件。谁能帮帮我吗？

public class CustomButton : System.Web.UI.WebControls.Button
{
    private string href = "";

    public CustomButton(string name = "Custom Button", string link = "~/errors/404.aspx", string css = "custom_button")
    {
        this.Text = name;
        this.href = link;
        this.CssClass = css;
        //this.OnClick += redirect;
        this.Attributes.Add("OnClick", "redirect");
    }
    protected void redirect(object sender, EventArgs e)
    {
        // I want this function to redirect the user to another page.
    }
}

您应该重写 OnClick 方法:

The OnClick method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
