推荐答案

我不喜欢知道你真正想做什么吗？



如果你想在浏览器中将html代码显示为文本，你需要使用其中一个来编码它code> HtmlEncode（...）方法。

I don't know what you are actually trying to do?

If you want to display the html code as text in a browser, you need to encode it using one of the HtmlEncode( ... ) methods.

如果我正确理解您，您想在连接到服务器的打印机上打印html页面吗？这听起来很奇怪，特别是对于一个网络应用程序。



无论如何，如果是这种情况，你需要一个html渲染引擎。最容易使用的是 System.Windows.Forms.WebBrowser 控件。



创建一个实例并将 DocumentText 属性设置为您的html字符串。处理加载html时触发的 DocumentCompleted 事件。然后设置你的打印作业并调用 WebBrowser.Print（）。



我无法想象为什么你我想这样做，但是：confused：

If I understand you correctly, you want to print an html page on a printer attached to your server? This sounds odd, especially for a web app.

Anyway, if that is the case, you need an html rendering engine. The easiest one to use is the System.Windows.Forms.WebBrowser control.

Create an instance of one and set the DocumentText property to your html string. Handle the DocumentCompleted event which fires when the html is loaded. Then set up your print job and call WebBrowser.Print().

I can't imagine why you would want to do this, though :confused:
