Types of Exceptions

Hi @E.T.S

  • System.ArgumentException: This exception occurs when an invalid argument is passed to a method or activity in UiPath. For example, if you try to pass a null value to a method that doesn’t accept null arguments, you might encounter this exception.

  • System.NullReferenceException: This exception occurs when you try to access or manipulate an object that is null. In UiPath, this might happen if you’re trying to use an activity or variable that hasn’t been properly initialized or assigned a value.

  • System.IO.IOException: This exception occurs when an I/O operation (such as reading or writing to a file) fails or is interrupted. In UiPath, this could happen if there’s an issue with accessing or manipulating files or directories using activities like Read Text File or Write Text File.

  • System.InvalidOperationException: This exception occurs when a method or operation is called in an invalid state. In UiPath, this could happen if you try to perform an action on a UI element that is not currently available or visible.

  • System.Exception: This is the base class for all exceptions in .NET. In UiPath, this could be thrown for various reasons, such as unexpected errors or when a specific exception type isn’t caught by a try-catch block.
