如何使 HtmlTextWriter 对象使用空格而不是制表符作为其缩进？
我正在从 WinForm 上运行的代码创建一些 html。 我想创建以下 html：
<html>
<body>
<div>
<p>foo</p>
</div>
</body>
</html>
我正在使用 System.Web.UI.HtmlTextWriter 类来执行此操作，如下所示：
System.Web.UI.HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter();
htmlWriter.WriteFullBeginTag("html");
htmlWriter.WriteLine();
htmlWriter.WriteFullBeginTag("body");
htmlWriter.WriteLine();
htmlWriter.Indent++;
htmlWriter.WriteFullBeginTag("div");
htmlWriter.WriteLine();
htmlWriter.Indent++;
htmlWriter.WriteFullBeginTag("p");
htmlWriter.Write("foo");
htmlWriter.WriteEndTag("p");
htmlWriter.Indent--;
htmlWriter.WriteLine();
htmlWriter.WriteEndTag("div");
htmlWriter.Indent--;
htmlWriter.WriteLine();
htmlWriter.WriteEndTag("body");
htmlWriter.WriteLine();
htmlWriter.WriteEndTag("html");
这工作得很好，但是，当我在文本编辑器中打开生成的 html 时，我的缩进看起来也太糟糕了对我来说很远，因为它使用制表符。 有没有办法强制此类使用多个空格？
I am creating some html from code running on a WinForm. I want to create the following html:
<html>
<body>
<div>
<p>foo</p>
</div>
</body>
</html>
I'm using the System.Web.UI.HtmlTextWriter class to do this like so:
System.Web.UI.HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter();
htmlWriter.WriteFullBeginTag("html");
htmlWriter.WriteLine();
htmlWriter.WriteFullBeginTag("body");
htmlWriter.WriteLine();
htmlWriter.Indent++;
htmlWriter.WriteFullBeginTag("div");
htmlWriter.WriteLine();
htmlWriter.Indent++;
htmlWriter.WriteFullBeginTag("p");
htmlWriter.Write("foo");
htmlWriter.WriteEndTag("p");
htmlWriter.Indent--;
htmlWriter.WriteLine();
htmlWriter.WriteEndTag("div");
htmlWriter.Indent--;
htmlWriter.WriteLine();
htmlWriter.WriteEndTag("body");
htmlWriter.WriteLine();
htmlWriter.WriteEndTag("html");
This works just fine, however, when I open the resulting html in a text editor my indentation just looks way too far to me, since it is using tab chars. Is there a way to force this class to use a number of spaces instead?

我不是 System.Web.UI 人员，而是来自 MSDN 文档，看起来您可以提供用于缩进的字符作为 HtmlTextWriter 构造函数的第二个参数。 因此，要获得 4 个空格而不是制表符：
I'm not a System.Web.UI guy, but from the MSDN documentation, it looks like you can supply the character to use for indentation as the second argument to the HtmlTextWriter constructor. Thus, to get 4 spaces instead of a tab:
大卫从技术上已经回答了你的问题，但这条路通向黑暗面。 客户端 Web 代码未编译。 如果您使用四个空格而不是制表符，那么您就做错了。
即使影响很小，什么时候可以接受效率降低 400%？ 如果您无缘无故地想让事情变慢一点，您也可以随机添加 Thread.Sleep() 调用到您的服务器端代码。

David has technically answered your question, but that path leads to the dark side. Client-side web code is not compiled. If you use four spaces instead of a tab character, you're doing it wrong.
Even if the impact is small, when is it acceptable to be 400% less efficient? If you want to make things a tiny bit slower for no good reason, you could also randomly add Thread.Sleep() calls to your server-side code.
Fix your text editor's settings.
