App.Current.Dispatcher.Invoke((Action)(() =>
{
myCollection.Add(measurement);
}));
我将一个Measurement对象添加到ObservableCollection<Measurement>并得到＆＃34;类型为'System.Reflection.TargetException' occurred in mscorlib.dll的第一次机会异常
其他信息：Object does not match target type.＆＃34;
我不明白为什么会被抛出，因为它们都是同一类型。 堆栈跟踪：

一致性检查崩溃了吗？奇怪的是，这并没有发生。请介绍一下这个
编辑：
如果我继续打击继续我会得到这个例外：
A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll
其他信息：Property accessor 'Vehicle' on object 'Location' threw the following exception:'Object does not match target type.'
