How to decode a Unicode character in a string
提问by M_K
How do I decode this string 'Sch\u00f6nen' (@"Sch\u00f6nen") in C#, I've tried HttpUtility but it doesn't give me the results I need, which is "Sch?nen".
我如何@"Sch\u00f6nen"在 C# 中解码这个字符串 'Sch\u00f6nen' ( )，我试过 HttpUtility 但它没有给我我需要的结果，即“Sch?nen”。

Regex.Unescapedid the trick:
Regex.Unescape做到了：
System.Text.RegularExpressions.Regex.Unescape(@"Sch\u00f6nen");
Note that you need to be careful when testing your variants or writing unit tests: "Sch\u00f6nen"is already "Sch?nen". You need @in front of string to treat \u00f6as part of the string.
请注意，在测试变体或编写单元测试时需要小心："Sch\u00f6nen"is already "Sch?nen"。您需要将@前面的字符串\u00f6视为字符串的一部分。

If you landed on this question because you see "Sch\u00f6nen"(or similar \uXXXXvalues in string constant) - it is not encoding. It is a way to represent Unicode characters as escape sequence similar how string represents New Line by \nand Return by \r.
如果您因为看到"Sch\u00f6nen"（或\uXXXX字符串常量中的类似值）而遇到此问题- 它不是编码。这是一种将 Unicode 字符表示为转义序列的方法，类似于 string 表示 New Line by\n和 Return by 的方式\r。
I don't think you have to decode.
我不认为你必须解码。
string unicodestring = "Sch\u00f6nen";
Console.WriteLine(unicodestring);
Sch?nen was outputted.
Sch?nen 被输出。
