我在解析从 javascript 文件（比如 xyz.js）中检索到的 JSON 数据时遇到问题。文件大小约为 10mb，其中只有一个 JSON 字符串。

我们直接使用javascript来解析这个文件，我想知道我们是否有任何C#类来解析这个文件？

JSON 字符串的示例是

var JSONString = {
    Level1:{
        DateTime:{
              date:'Wed Sep 14 14:19:32 CDT 2011'
        },
        information:{
              url:'http:\\www.google.com'
        },
        RepetitiveLevel:[
            {
                ids:{
                    courses:[
                        "BE",
                        "MS"
                    ]
                },
                SubRepetitiveLevels:{
                    DetailedLevel:[
                        {
                            name:"Trial 1",

The tag named "RepetitiveLevel" will be repeating more than 10 times 
Under this tag, there will be repetitions of "SubRepetitiveLevels", which in turn contains more than one entry for "DetailedLevel". 
This kind of JSON string fails for Newtonsoft.Json.JsonConvert.DeserializeObject 

   I know this is a little bit confusing, but we are not finding any other option.

任何帮助就足够了。提前致谢。

试试这个库。我们在一个 ASP.NET 项目中使用它，它运行良好。

该程序通过序列化/反序列化写入然后读取 100mb 文件。

class Program
{
    static void Main(string[] args)
    {
        var lst = new List<string>();
        for (var i = 0; i < 1024 * 1024 * 10; i++)
        {
            lst.Add(i.ToString());
            if(i%(1024 * 1024)==0)Console.WriteLine("+1m");
        }
        var wrt = Newtonsoft.Json.JsonConvert.SerializeObject(lst);
        lst = null;
        File.WriteAllText(@"F:\1.txt",wrt);
        Console.WriteLine("written");
        wrt = "";
        GC.Collect();
        wrt=File.ReadAllText(@"F:\1.txt");
        lst=Newtonsoft.Json.JsonConvert.DeserializeObject<List<string>>(wrt);
        Console.WriteLine("read");
        Console.WriteLine(lst.Count.ToString());
    }
}
