| Name | Description | |
|---|---|---|
![]() | ConfigurationValidatorAttribute() | Initializes a new instance of the ConfigurationValidatorAttribute class. |
![]() | ConfigurationValidatorAttribute(Type^) | Initializes a new instance of the ConfigurationValidatorAttribute class using the specified validator type. |
| Name | Description | |
|---|---|---|
![]() | TypeId | |
![]() | ValidatorInstance | Gets the validator attribute instance. |
![]() | ValidatorType | Gets the type of the validator attribute. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object^) | This API supports the product infrastructure and is not intended to be used directly from your code. 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.) |
![]() | GetHashCode() | Returns the hash code for this instance.(Inherited from Attribute.) |
![]() | GetType() | |
![]() | 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.) |
![]() | Match(Object^) | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.) |
![]() | MemberwiseClone() | |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr) | Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfo(UInt32, UInt32, IntPtr) | Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfoCount(UInt32%) | Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.) |
![]() ![]() | _Attribute::Invoke(UInt32, Guid%, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) | Provides access to properties and methods exposed by an object.(Inherited from Attribute.) |
All the ASP.NET configuration standard validator attribute types derive from ConfigurationValidatorAttribute. You can use this type to create your own custom validator attribute.
The following code examples demonstrate how to create two custom validators using the ConfigurationValidatorAttribute type. The first example performs validation using hard-coded parameters; the second example performs validation using the parameters assigned to it at the time it is applied to the related section property. This code example also contains three supporting files. The first file contains the custom section that uses the validators described above, the second file contains a custom converter type, and the third file contains the console application that builds and uses the custom validators and the section that contains them.
The following code example shows how to create a fixed validator with hard-coded parameters.
The following code example shows how to create a programmable validator.
The following code example shows how to create a custom section using the previous validators.
The following code example shows how to create a custom converter.
The following code example shows how to create the console application that builds and uses the custom validators and their containing section.
The following code example is a configuration excerpt used by the previous example.
