NameDescription
System_CAPS_pubmethod DesignTimeResourceProviderFactoryAttribute

Initializes a new instance of the DesignTimeResourceProviderFactoryAttribute class with the attribute set to the specified factory type name.

System_CAPS_pubmethod DesignTimeResourceProviderFactoryAttribute

Initializes a new instance of the DesignTimeResourceProviderFactoryAttribute class with the attribute set to the qualified name of the specified factory type.

NameDescription
System_CAPS_pubproperty

Gets the value of the factory type name.

System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethod Equals

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.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod IsDefaultAttribute

Determines whether the default provider is used.(Overrides AttributeIsDefaultAttribute.)

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The DesignTimeResourceProviderFactoryAttribute class allows a ResourceProviderFactory object to specify the type of the associated DesignTimeResourceProviderFactory object. The DesignTimeResourceProviderFactory class is used to create design-time providers for reading and writing resources. Within Microsoft Visual Studio 2005, a developer can use the Generate Local Resource command on the Tools menu to create resources during design time.

The following code example shows a customized resource provider factory that specifies a customized design-time resource provider factory through the DesignTimeResourceProviderFactoryAttribute attribute. This example does not include the code necessary to implement a customized design-time resource provider factory.
