jsonSerializer.Deserialize对于C＃中的Unicode字符无法正常工作

Question

I want to deserialise a JSON object containing unicode data to string array. While the characters inside the JSON object is english, it works fine. But when I use chinese it won't.

JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
string[] SampleText = jsonSerializer.Deserialize<string[]>(HttpContext.GetGlobalResourceObject("Resource", "SampleText").ToString());

When I run this in Immediate window of visual studio, the out comes like this for English

jsonSerializer.Deserialize<string[]>(HttpContext.GetGlobalResourceObject("Resource", "SampleText").ToString());
{string[3]}        
    [0]: "Size"
    [1]: "Name"
    [2]: "Type"

But for chinese an exception occurs

base {System.SystemException}: {"Invalid JSON primitive: ."}
Message: "Invalid JSON primitive: ."
ParamName: null

The resourse file value for english and chinese

["Size","Name","Type"]
[“大小”，“姓名”，“類型”]

Answer 1

EDIT: I just noticed that the japanese text is surrounded by smart quotes “ ” instead of actual quotes " . Replace the smart quotes with simple quotes. No language that I know of uses smart quotes as text delimiters, they are treated as content. Your text also uses a non-comma character ， (hex ff0c) instead of a comma.

Strings in .NET are Unicode. It isn't possible to create a non -Unicode string.

Problems occur only when you try to read non-Unicode content (like a file encoded in a specific codepage) as if it were a Unicode file. The OS (and .NET) will use the system locale to read non-unicode files which can result in garbled data. The solution is to either save files with Unicode encoding, or explicitly specify the file's encoding if it's different than the system locale.

In your case, the resource file is most likely not saved as a Unicode (or UTF8) file. Previous versions of Visual Studio saved files (including web pages) using the system's locale by default which resulted in some pretty interesting problems for non-US developers.

Examine the string returned by HttpContext.GetGlobalResourceObject("Resource", "SampleText").ToString() . The content will probably be garbled, which means the original string was not saved as Unicode.

The solution may be as simple as converting the resource file to Unicode.

Yes, You need to first convert resx value to unicode and then use that value to deserialize JSON value and then convert to string array...
