HtmlEncode from Class Library
提问by Villager
I have a class library (in C#). I need to encode my data using the HtmlEncode method. This is easy to do from a web application. My question is, how do I use this method from a class library that is being called from a console application?
我有一个类库（在 C# 中）。我需要使用 HtmlEncode 方法对我的数据进行编码。这很容易从 Web 应用程序中完成。我的问题是，如何从控制台应用程序调用的类库中使用此方法？

Import System.Web Or call the System.Web.HttpUtility which contains it
导入 System.Web 或调用包含它的 System.Web.HttpUtility
You will need to add the reference to the DLL if it isn't there already
如果 DLL 不存在，您将需要添加对 DLL 的引用
string TestString = "This is a <Test String>.";
string EncodedString = System.Web.HttpUtility.HtmlEncode(TestString);

If you are using C#3 a good tip is to create an extension method to make this even simpler. Just create a static method (preferably in a static class) like so:
如果您使用的是 C#3，一个很好的提示是创建一个扩展方法来使这更简单。只需创建一个静态方法（最好在静态类中），如下所示：
public static class Extensions
{
public static string HtmlEncode(this string s)
{
return HttpUtility.HtmlEncode(s);
}
}
You can then do neat stuff like this:
然后你可以做这样的整洁的事情：
string encoded = "<div>I need encoding</div>".HtmlEncode();
