json.net反序列化抛出异常时，JSON是从项目资源加载 [英] json.net deserialization throwing exception when json is loaded from project resource

问题描述

这是产生问题的反序列化：

This is the deserialization that produces the problem:

public MyType ProblematicDeserialization(jsonString)
{
    return Newtonsoft.Json.JsonConvert.DeserializeObject<MyType>(jsonString);   
}

它的工作原理，或不deppending上jsonString的加载方式：

It works or it doesn't deppending on how jsonString is loaded:

案例1：

myObjectType 连载与json.net作为一个字符串，然后写入文件路径：

myObjectType serialized with json.net as a string and then written into filePath:

//This line works correctly:
dynamic correctlyWorkingJson = IO.File.ReadAllText(filePath, Text.Encoding.UTF8);

CASE 2

相同的 CASE 1 ，但含量文件路径已被复制，然后粘贴到我的项目一个JSON资源：

Same as CASE 1, but the content of filePath has been copied and then pasted into a json resource in my project:

//This line gives an ERROR: ""Unexpected character encountered while parsing value: . Path '', line 0, position 0."
dynamic notWorkingJson = GetJsonFromResource(resourceName);

private string GetJsonFromResource(string resourceName)
{
    byte[] jsonBytes = Convert.ToByte(ResourcesManager.GetResource(resourceName));
    if (jsonBytes == null) {
        throw new Exception(string.Format("Resource '{0}.json' was not found.", resourceName));
    }
    string json = UTF8BytesToString(jsonBytes);
    return json;
}

在调试器，无论是 correctlyWorkingJson 和 notWorkingJson 看完全一样的，但显然是有东西让为json.net反序列化不能接受的资源JSON。

On the debugger, both correctlyWorkingJson and notWorkingJson look exactly the same, but obviously there is something that makes the resource json not acceptable for the json.net deserialization.

推荐答案

在/ U / DBC的评论，该字节序列表明，资源文件的编码是UTF-8-BOM，我解决了这种方式：

After /u/dbc's comment that the byte sequence indicated that the encoding of the resource file was UTF-8-BOM, I solved it this way:

• 我去盘源文件在我的项目当作一个资源


• 我用记事本++


• 编码编辑它 - >转换为UTF-8

之后，贴在原岗位完全相同的代码工作完美。

After that, the exact same code posted in the original post worked perfectly.
