How Can I Implement Global Exception Handling in Console Applications?

Global abnormal treatment in the console application

In the console application, the unprocessed abnormalities may interrupt the execution of the application and may cause data loss. To prevent this, a global abnormal processing process can be defined to capture and deal with these abnormalities elegantly.

Customized global abnormal treatment

The AppDomain class provides a unhandleDexception event, which can subscribe to the event to define the global abnormal processing program. In the .NET 2.0 and higher versions, the following code can be used:

vb.net Precautions

<code class="language-csharp">AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyExceptionHandler);</code>

When working in vb.net, please note that you must use the "AddHandler" keyword before the AppDomain.Currentdomain object. As shown below:

Example implementation

<code class="language-vb.net">AddHandler AppDomain.CurrentDomain.UnhandledException, New UnhandledExceptionEventHandler(AddressOf MyExceptionHandler)</code>

The following C# code provides a basic example of the console application global abnormal processing program:

Note:

The types and file loading of CLR during the JIT compilation cannot be captured by the global abnormal processing program. To deal with these abnormalities, consider delaying or applied

attributes to risk code.
