Represents the exception that occurs during validation of a data field when the ValidationAttribute class is used.

[System.Serializable]
public class ValidationException : Exception

type ValidationException = class

[<System.Serializable>]

Public Class ValidationException
Inherits Exception

Inheritance: Object

Attributes: SerializableAttribute

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)	Obsolete. 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.

Properties

Data	Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception)
HelpLink	Gets or sets a link to the help file associated with this exception. (Inherited from Exception)
HResult	Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception)
InnerException	Gets the Exception instance that caused the current exception. (Inherited from Exception)
Message	Gets a message that describes the current exception. (Inherited from Exception)
Source	Gets or sets the name of the application or the object that causes the error. (Inherited from Exception)
StackTrace	Gets a string representation of the immediate frames on the call stack. (Inherited from Exception)
TargetSite	Gets the method that throws the current exception. (Inherited from Exception)
ValidationAttribute	Gets the instance of the ValidationAttribute class that triggered this exception.
ValidationResult	Gets the ValidationResult instance that describes the validation error.
Value	Gets the value of the object that causes the ValidationAttribute class to trigger this exception.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetBaseException()	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetObjectData(SerializationInfo, StreamingContext)	Gets information about the exception and adds it to the SerializationInfoEnumerator object.
GetObjectData(SerializationInfo, StreamingContext)	Obsolete. When overridden in a derived class, sets the SerializationInfo with information about the exception. (Inherited from Exception)
GetType()	Gets the runtime type of the current instance. (Inherited from Exception)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Creates and returns a string representation of the current exception. (Inherited from Exception)

Events

SerializeObjectState

Obsolete.

Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.
