C # Processing of Chinese in JSON-based communication

If the \\u4e00-\\u9fa5 range of Chinese Unicode code is generated in the communication, instead of the \u4e00-\u9fa5 range, then C # processing is more troublesome.

Crack method: Mechanism

It will split the \\u4e00 into parts to identify: \ \ u4e00, the magic is that in this case, it will think u4e000 is a whole.

Regular expressions

Regular expressions need to be written like this: "[\\\\4e00-\\\\u9fa5]", it WORKS!!! Although it is a two-part.

Interface display

But the problem is that the interface (WinForm) shows Unicode, this time in order for our UI to display the Chinese characters properly, we need to replace \ \.

Looks like a replace can be done, not also!

Mode 1:

' \ \ ' character

"\" error. Blocked

Mode 2:

@ "\ \", "\\\\"

@ "\", "\ \"

This is the opposite.

Mode 3:

Customize an algorithm to complete the \ \ to \ Conversion.

Ideas:

Each character, in fact, is a number in the computer.

For example ' 1 ', the corresponding ASCII code is 49. For Chinese characters, there is GB2312 code, in the final analysis is a number. A Chinese character corresponds to a number (usually denoted by a 16 binary representation)

As long as the numerical value (19968) is calculated, such as \\u4e00, and the corresponding to the Chinese character can be. That is

char Hz = (char) 0x4e00

The next problem is to turn "\\u4e00" into 0x4e00, and the code is as follows:
