How to get a button to open a web page?
提问by Lewis Clark
I've looked everywhere, including the MSDN forums, but no one has even mentioned this or ways to do it. The basic idea is that once a Button is dragged from the toolkit, how do you then link that button to a web page, ie I have a 'Facebook' button, how do I then make it so that when the button is clicked, Facebook opens in a new browser window?
我到处找，包括 MSDN 论坛，但没有人甚至提到过这一点或这样做的方法。基本思想是，一旦从工具包中拖出一个按钮，您如何将该按钮链接到网页，即我有一个“Facebook”按钮，然后我如何制作它以便在单击该按钮时，Facebook在新的浏览器窗口中打开？

Once you've dragged the button onto the designer, you can double-click on it to open up the Button's Clickevent handler. This is the code that will get run when the user clicks. You can then add the required logic, ie:
将按钮拖到设计器上后，您可以双击它以打开 Button 的Click事件处理程序。这是将在用户单击时运行的代码。然后您可以添加所需的逻辑，即：
private void button1_Click(object sender, EventArgs e)
{
// Launch browser to facebook...
System.Diagnostics.Process.Start("http://www.facebook.com");
}

Since you said open in a newbrowser window, I was thinking the context was an web application you were developing, so this would apply in that case:
由于您说在新的浏览器窗口中打开，我认为上下文是您正在开发的 Web 应用程序，因此这适用于这种情况：
Add an HTML button with the window.openJavaScript method. You don't need or want code-behind here because it's all happening on the client. Here's a snippet, and there are a few other options you can pass to window.opento control behavior.
使用window.openJavaScript 方法添加 HTML 按钮。您不需要或不想要代码隐藏在这里，因为这一切都发生在客户端上。这是一个片段，您可以传递一些其他选项window.open来控制行为。
<input id="Button2" type="button" value="Facebook" onclick="window.open('http://facebook.com')"/></p>

You have to use Process classunder System.dllwhich is be default added to the solution. But you should refer the namespace at the top of your class this way:
你必须使用Process class下System.dll这是默认添加到溶液中。但是您应该以这种方式引用类顶部的命名空间：
using System;
namespace MyApplication
{
public class MyProgram
{
private void button1_Click(object sender, EventArgs e)
{
System.Diagnostics.Process.Start("http://www.facebook.com");
}
}
}

You can use Process.Start with the desired URL to open the default browser and navigate to the page:
您可以使用带有所需 URL 的 Process.Start 打开默认浏览器并导航到页面：
using system.Diagnostics;
private void button1_Click(object sender, EventArgs e)
{
Process.Start("http://www.YouTube.com");
}
