Remarks

A ValidationException exception is thrown when an input value does not match the allowed values for the member as specified by a validation attribute. For example, the framework throws an exception when validating an integer value that is outside of the integer range specified by the RangeAttribute attribute. You specify the allowed values for a member by applying a validation attribute to the member. A validation attribute is an attribute that derives from ValidationAttribute.

You can catch the ValidationException to retrieve information about the error.
