Dim instance As ClassValidationAttributepublic ref class ClassValidationAttribute abstract : public AttributeClass validators are executed when all arguments have been parsed, and allow you to check whether the whole set of arguments meets a condition. Use this instead of ArgumentValidationAttribute if the type of validation being performed doesn't belong to a specific argument, or must be performed even if the argument(s) don't have values.
If validation fails, it will throw a CommandLineArgumentException with the category specified in the ErrorCategory property. The ParseT(String, Int32, ParseOptions) method and the CommandManager class will automatically display the error message and usage help if validation failed.
A built-in validator is provided, and you can derive from this class to create custom validators.
| ClassValidationAttribute | Initializes a new instance of the ClassValidationAttribute class |
| ErrorCategory | Gets the error category used for the CommandLineArgumentException when validation fails. |
| TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute) |
| Equals | Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetErrorMessage | Gets the error message to display if validation failed. |
| GetHashCode | Returns the hash code for this instance. (Inherited from Attribute) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| GetUsageHelp | Gets the usage help message for this validator. |
| IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute) |
| IsValid | When overridden in a derived class, determines if the arguments are valid. |
| Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
| Validate | Validates the argument value, and throws an exception if validation failed. |
