将字符串转换为普通文本

Question

When I open one file it contains something like this:

It's that

What is this and how do I convert it to ASCII ?

Answer 1

This is HTML encoding, use WebUtility.HtmlDecode (in System.Net namespace):

string encoded = "It's that";
string decoded = System.Net.WebUtility.HtmlDecode(s);

Answer 2

HttpUtility.HtmlDecode()可以解决问题。

Answer 3

Those are HTML entities. They represent ascii characters. You can decode them using HttpUtility.HTMLDecode().

If you're just trying to read this one line, you could also rename the file to a .html file and open it in your browser of choice. There are even tools that do this online.

Answer 4

The number between the &# ; is likely an ASCII code.
Convert the numbers manually or use the HTMLDecode to save yourself some time...

Answer 5

If you're using .Net Framework 4.0 or higher then the System.Net.WebUtility.HtmlDecode(s) will work.

I needed this solution for an SSRS report where only 3.5 was supported. Since the namespace above wasn't available I went the alternate route of

System.Web.HttpUtility.HtmlDecode(rawString)
