System_CAPS_pubpropertyValidationAttribute

Gets the instance of the ValidationAttribute class that triggered this exception.

System_CAPS_pubpropertyValidationResult

Gets the ValidationResult instance that describes the validation error.

NameDescription
System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetObjectData(SerializationInfo^, StreamingContext)

When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.)

System_CAPS_pubmethodGetType()

Gets the runtime type of the current instance.(Inherited from Exception.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Creates and returns a string representation of the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_proteventSerializeObjectState

Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.)

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.
