我写这段代码:
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
定义为:
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; }
}
当我将JSON字符串从客户端发送到我的服务器时,我的服务器转到HTTP处理程序并返回以下JSON字符串,所有这些都按预期进行。
[
{
f_id:100,
r_id:200,
count:2,
c_id=111
},
{
f_id:120,
r_id:200,
count:1,
c_id=111
}
]
但是当程序遇到这一行时:
List<myClass> tmp = JsonConvert.DeserializeObject<List<myClass>>(jsonString);
我的服务器因以下异常而崩溃。

答案 0 :(得分:1)
json&#34; c_id = 111&#34;字符串无效。正确的json应始终位于key:value对中。键值应该用冒号(:)分隔。 { F_ID:100, R_ID:200, 数:2, 的 C_ID = 111 强> }, { F_ID:120, R_ID:200, 数:1, 的 C_ID = 111 强> }
正确的json应如下所示: { F_ID:100, R_ID:200, 数:2, 的 C_ID:111 强> }, { F_ID:120, R_ID:200, 数:1, 的 C_ID:111 强> }
因此,只需验证&#34; context.Request.InputStream&#34;中包含的数据。分析这个问题可能会有所帮助。
