ValidationException Constructor (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.

Namespace:  System.ComponentModel.DataAnnotations
Assembly:  System.ComponentModel.DataAnnotations (in System.ComponentModel.DataAnnotations.dll)

public ValidationException(
	string errorMessage,
	ValidationAttribute validatingAttribute,
	Object value
)

Parameters

errorMessage
Type: System.String

The message that describes the error.

validatingAttribute
Type: System.ComponentModel.DataAnnotations.ValidationAttribute

The attribute that caused the current exception.

value
Type: System.Object

The value of the object that caused the attribute to trigger validation error.

This constructor initializes a new instance of the ValidationException class using the specified parameters. For example, if a range attribute requires a range of values from 1 to 10 and a value of 20 is received as input, the new validation exception that is thrown will be constructed. The following code snippet shows the range attribute:

[Range(1,10)]

public object number;

The validation exception that is constructed will resemble the following code snippet:

throw new ValidationException("This value has to be between 1 to 10",RangeAttribute, 20);

Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
