An exception is an event that occurs during the execution of a program that disrupts the normal flow of instructions, and requires special handling. Exception has been thrown by the target of an invocation is an exception that occurs when a method is invoked, but an error occurs during the invocation. In this article, we will discuss what an exception is, and how to handle an exception when it arises.
What Is An Exception?
An exception is an event that occurs during the execution of a program that disrupts the normal flow of instructions. It is usually caused by either a programming error or invalid user input. When an exception occurs, the program will usually stop and display an error message. Exceptions can be handled in a variety of ways, depending on the type of exception and the programming language being used.
How To Handle An Exception?
When an exception occurs, it is important to take the appropriate steps to handle it. The first step is to identify the type of exception that has occurred and determine the cause of the exception. Once the cause has been identified, the necessary steps can be taken to resolve the issue. Depending on the programming language and type of exception, there are different ways to handle it. For example, in Java, a try-catch statement can be used to catch exceptions and handle them accordingly.
Exception has been thrown by the target of an invocation is an exception that occurs when a method is invoked, but an error occurs during the invocation. It is important to take the appropriate steps to handle the exception so that the program can continue running. Depending on the programming language and type of exception, there are different ways to handle it. By understanding what an exception is and how to handle it, programmers can ensure that their programs run smoothly and efficiently.
An “Exception Has Been Thrown By The Target Of An Invocation” is an error message that triggers when a Microsoft .NET application encounters an exception which cannot be handled. It usually appears when a tried to call a method, but the call failed because the target method met an unexpected problem, such as an invalid parameter.
The exception is called an “unhandled exception” as the calling application doesn’t know how to handle it. The exception message is generally seen within a dialog box, indicating the application encountered a problem, and the application may quit in response to the exception.
In some cases, the exception is user-friendly enough to help the user in determining the underlying cause of the exception. In other cases, it may be incomprehensible, as the user may not understand the instructions represented by the targeted invocation.
When an issue like this occurs, an experienced software developer is required to find out what happened. The developer will have to track down the origin of the exception, and then address or repair the issue. In some cases, the underlying cause of the Exception Has Been Thrown By The Target Of An Invocation error message may be related to an input parameter or a corrupted .NET managed application, or plugin.
.NET developers should be aware that this exception could be handled if the try/catch code block is correctly applied in the method call. In this case, the code block first runs the method and captures the exception, and then performs the appropriate response (generally, the application should provide a logical response to handle the error, instead of crashing.) Developers should also pay attention to the latest Microsoft .NET Framework service packs, as it is possible that the exception is a result of a bug that has already been fixed in an available update.
It is important to have an experienced .NET developer analyse the issue, and trace it back to its origin. Doing this will enable the developer to address the issue and minimize the chance of similar exceptions in the future.
