问题描述

这个 XAMLParseException 快把我逼疯了！！我在 Visual Studio 1020 中使用 .NET 3.5 这是我的 xaml:

THIS XAMLParseException IS DRIVING ME CRAZY!! I am using .NET 3.5 in Visual Studio 1020 This is my xaml:

推荐答案

我认为这不是一个真正的 XamlParseException:我认为它是一个 TargetInvocationException，它被包装在一个 XamlParseException 中.看看最终的内部异常:

I don't think this is really a XamlParseException: I think it's a TargetInvocationException which has gotten wrapped in a XamlParseException. Take a look at the ultimate inner exception:

NLog.Config.NLogConfigurationException消息=加载时发生异常配置来自'C:\Users\Mohit\Documents\Visual工作室2010\Projects\Notepad\Notepad\bin\Debug\NLog.config'

NLog.Config.NLogConfigurationException Message=Exception occured when loading configuration from 'C:\Users\Mohit\Documents\Visual Studio 2010\Projects\Notepad\Notepad\bin\Debug\NLog.config'

看起来您的配置文件已损坏，可能是由于无效的 XML 或某些更具体的原因.

It looks like you have a borked configuration file, possibly due to invalid XML or possibly for some more specific reason.

当您收到一个神秘的 XamlParseException 时，总是值得检查 InnerException 是否有 TargetInvocationException(如果有的话，从那里钻进去).是的，它非常令人困惑和误导！

When you get a mysterious XamlParseException, it's always worth checking the InnerException for a TargetInvocationException (and drilling in from there if there is one). Yes, it is very confusing and misleading!
