Question

有时当我的应用程序尝试启动时，抛出ArgumentException“参数不正确”。不幸的是，异常是随机发生的，所以很难修复它。

InnerException和StackTrace为空：（。

这是输出：

有时一切正常，但有时我连续10次无法运行应用程序。

编辑1：调用堆栈：

SmartLib.dll！SmartLib.App.Application_UnhandledException（object sender = {SmartLib.App}，System.Windows.ApplicationUnhandledExceptionEventArgs e = {System.Windows.ApplicationUnhandledExceptionEventArgs}）第348行+ 0x5字节C＃       System.Windows.dll！MS.Internal.Error.CallApplicationUEHandler（System.Exception e = {“参数不正确。”}）+ 0x30字节

编辑3：

根据Stack Trace，它似乎是由第一页可视化中的一些错误引起的。但根据我的分析:)它似乎是由从服务器获取错误的错误引起的。

APP信息：

我的应用程序提供有关图书馆图书的信息。有时当应用程序启动并尝试更新图书评级时，应用程序将崩溃。应用程序在获得响应之前崩溃。我使用RestSharp Library发送HTTP请求。

确定。似乎问题与此问题相同：
