HtmlDecode of html encoded space is not space
提问by user1481853
Till now I was thinking HttpUtility.HtmlDecode(" ")was a space. But the below code always returns false.
直到现在我还在想HttpUtility.HtmlDecode(" ")是一个空间。但是下面的代码总是返回false。
string text = " ";
text = HttpUtility.HtmlDecode(text);
string space = " ";
if (String.Compare(space, text) == 0)
return true;
else
return false;
Same when I try with Server.HtmlDecode()
当我尝试使用时相同 Server.HtmlDecode()
Why is it so?
为什么会这样？
Any help would be much appreciated
任何帮助将非常感激
Thanks, N
谢谢，N

The HTML entity doesn't represent a space, it represents a non-breaking space.
HTML 实体 不代表一个空格，它代表一个不间断的空格。
The non-breaking space has character code 160:
不间断空格的字符代码为 160：
string nbspace = "\u00A0";
Also, as Marc Gravell noticed, you have double encoded the code, so you would need to decode it twice to get the character:
此外，正如 Marc Gravell 所注意到的，您对代码进行了双重编码，因此您需要对其进行两次解码才能获得字符：
string text = " ";
text = HttpUtility.HtmlDecode(HttpUtility.HtmlDecode(text));

I'm cleaning the html like this:
我正在像这样清理 html：
var text = WebUtility.HtmlDecode(html)
.Replace("\u00A0", " ") // Replace non breaking space with space.
.Replace(" ", " ") // Shrink multiple spaces into one space.
.Trim();

The HTML of  doesn't mean anykind of space. It means, literally, the text - for example, if you were writing HTML that was talking about HTML, you may need to include the text , which you would do by writing the HTML  .
的 HTML 并不意味着任何类型的空间。它的字面意思是文本 - 例如，如果您正在编写谈论 HTML 的 HTML，您可能需要包含 text ，您可以通过编写 HTML 来实现 。
If you had:
如果你有：
string text = " ";
then thatwould decode to a non-breakingspace.
那么这将解码为一个不间断的空间。

Hello I faced the same issue some minutes ago.
I solved it in this way:
您好，我几分钟前遇到了同样的问题。
我是这样解决的：
string text = " ";
text = Server.HtmlDecode(text).Trim;
so now:
text = ""is true (the Trim at the end eliminates the space)
所以现在：
text = ""是真的（最后的修剪消除了空间）
