asp.net parse the array json using json.net

Question

I write this code:

public void ProcessRequest(HttpContext context)
{
    string m_order;

    try
    {
        var jsonSerilizer = new JavaScriptSerializer();
        var jsonString = String.Empty;
        context.Request.InputStream.Position = 0;
        using (var inputStream = new StreamReader(context.Request.InputStream))
        {
            jsonString = inputStream.ReadToEnd();
        }

        List<myClass> tmp = JsonConvert.DeserializeObject<List<myClass>>(jsonString);

        for (int i = 0; i < tmp.Count(); i++)
        {
            File.AppendAllText(@"d:\status\LOL.txt", "tmp["+(i+1)+"].rid=" +tmp[i].r_id  + "\r\n", Encoding.UTF8);

        }

myClass is defined as:

public class myClass
{
    public int f_id{get; set; }
    public int r_id { get; set; }
    public int count { get; set; }
    public int c_id { get; set; }
}

When I send the JSON string from the client to my server, my server goes to the HTTP Handler and returns the following JSON string, all as expected.

[
    {
        f_id:100,
        r_id:200,
        count:2,
        c_id=111
    },
    {
        f_id:120,
        r_id:200,
        count:1,
        c_id=111
    }
]

But when program hits this line:

List<myClass> tmp = JsonConvert.DeserializeObject<List<myClass>>(jsonString);

my server crashes with the following exception.

Newtonsoft.Json.JsonReaderException: Invalid JavaScript property identifier character: =. Path '[0].count', line 2, position 32.

Answer 1

The json "c_id=111" string is invalid. The correct json should always be in key:value pair. Key value should be separated by colon (:). { f_id:100, r_id:200, count:2, c_id=111 }, { f_id:120, r_id:200, count:1, c_id=111 }

The correct json should look like this: { f_id:100, r_id:200, count:2, c_id:111 }, { f_id:120, r_id:200, count:1, c_id:111 }

So, just verify the data contained in "context.Request.InputStream". It might be helpful to analyze this issue.
