c# - 当我尝试将JArray转换为线程中的对象时出现System.TypeLoadException

我有一个C#代码，它将JArray对象 jsonArray (JSON.Net)转换为对象列表 jsonList (List ):

List<MyClass> jsonList = jsonArray.ToObject<List<MyClass>> ();

上面的代码在主线程上运行时可以正常工作，但是如果我将相同的代码放在另一个线程中，则如下所示:

Thread t = new Thread(delegate() {
    List<MyClass> jsonList = jsonArray.ToObject<List<MyClass>> ();
});
t.Start();

我收到以下错误消息:“引发了System.TypeLoadException。发生了类型加载异常”。

有人知道为什么会这样吗？完整的堆栈跟踪如下。提前致谢!

最佳答案

似乎您正在为此开发基于触摸的应用程序，因此您需要用于Mono Touch的最新版本的NewtonSoft。可从here获取它。

如果要为现代UI构建它，则非常容易遵循Win 8模板或使用“任务”来启动线程。

尝试放入Try，Catch，Finally块以获取异常详细信息。
