这是WinForm项目，源中的\u52c7\u6c14等要转换为中文。

Answer 1

//需要引用附件dll
TextReader reader = File.OpenText("json.txt");
JsonReader readerJson = new JsonTextReader(reader);
Dictionary<object, object> dict = new Dictionary<object, object>();
object temp = new object();
while (readerJson.Read())
{
    if (readerJson.Value != null)
    {
        switch (readerJson.TokenType)
        {
            case JsonToken.PropertyName:
                dict.Add(readerJson.Value, new object());
                temp = readerJson.Value;
                break;
            default:
                dict[temp] = readerJson.Value;
                break;
        }
        Console.WriteLine(readerJson.TokenType + "\t" + readerJson.Value);
    }
}

谢谢！出现未处理的JsonReaderException，请问怎么解决？

追答

我用你给的那段没问题哈，是不是你的json和上面的不同呢？

请问怎么将上述代码中的reader（也就是json输入源）改为string类型，这样更方便使用，麻烦了。

追答

TextReader t = new StringReader("json 就写在这里");//StringReader 就可以带json字符串参数了

using System;

using System.Linq;
using System.Text;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text.RegularExpressions;
using System.Web.Script.Serialization;

namespace PublicUse.Text

public class JsonSerz

public static string JsonSerializer<T>(T t)

JavaScriptSerializer jsonSerialize = new JavaScriptSerializer();
return jsonSerialize.Serialize(t);

}

/// <summary>

public static T JsonDeserialize<T>(string jsonString)

}

}
}追问

WinForm项目好像没有using System.Web.Script.Serialization;
而且我提供的源中含有有unicode中文字符，是不是要先转换？
真心求代码，劳烦了。

追答

添加引用System.Web;System.Web.Extensions;
中文的好像也可以用。

Answer 4

告你个办法把，建好这个模型的对象，然后直接用jsonSerialize.Deserialize反解析到类型中就行了
