Properties

Remarks

The Autodesk.Revit.Exceptions.ArgumentException is a subclass of the System.ArgumentException and the Autodesk.Revit.Exceptions.RevitException classes. It is used to indicate that an argument is invalid or outside of the acceptable bounds when passed to a method or constructor.

This exception can be raised by almost any method or constructor in the Revit API when an argument is invalid. The exception message will generally contain information about which argument is invalid and why it is invalid.

Example

using Autodesk.Revit.Exceptions;

try
{
    // invalid argument passed to method
    SomeRevitMethod(null);
}
catch (ArgumentException ex)
{
    TaskDialog.Show("Error", ex.Message);
}

In the example above, a SomeRevitMethod method call is made with a null argument. This causes an Autodesk.Revit.Exceptions.ArgumentException to be thrown, which is caught using a try...catch block. The exception message is displayed in a TaskDialog popup.
