Remarks

A validation exception occurs if an input value does not match the expected data type, range or pattern of the data field. For example, if a user enters an integer value in a data field that expects a DateTime value, a validation exception occurs.

This class uses the ValidationAttribute class to customize validations. A ValidationException is thrown if a validation error occurs. The exception is thrown when the Validate method is called. All the exceptions that are thrown during validation are contained in the InnerExceptions collection. You can retrieve each validation exception by iterating through the InnerExceptions collection.

Constructors

ValidationException()

Initializes a new instance of the ValidationException class using an error message generated by the system.

ValidationException(SerializationInfo, StreamingContext)

Initializes a new instance of the ValidationException class using serialized data.

ValidationException(String)

Initializes a new instance of the ValidationException class using a specified error message.

ValidationException(String, Exception)

Initializes a new instance of the ValidationException class using a specified error message and a collection of inner exception instances.

ValidationException(String, ValidationAttribute, Object)

Initializes a new instance of the ValidationException class using a specified error message, a validation attribute, and the value of the current exception.

ValidationException(ValidationResult, ValidationAttribute, Object)

Initializes a new instance of the ValidationException class by using a validation result, a validation attribute, and the value of the current exception.
