Assembly: mscorlib (in mscorlib.dll)
| Name | Description | |
|---|---|---|
![]() | ProgIdAttribute(String) | Initializes a new instance of the ProgIdAttribute with the specified ProgID. |
| 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.) |
![]() | 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.) |
![]() | 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.) |
You can apply this attribute to classes.
ProgIDs are automatically generated for a class by combining the namespace with the type name. This can produce an invalid ProgID however, as ProgIDs are limited to 39 characters and can contain no punctuation other than a period. In such case, a ProgID can be manually assigned to the class using ProgIdAttribute.
The following example demonstrates how to apply ProgIdAttribute on a class. The application then gets all attributes of MyClass, and prints the Value property of ProgIdAttribute.
[ClassInterface(ClassInterfaceType.AutoDispatch)] [ProgId("InteropSample.MyClass")] public class MyClass { public MyClass() {} } class TestApplication { public static void Main() { try { AttributeCollection attributes; attributes = TypeDescriptor.GetAttributes(typeof(MyClass)); ProgIdAttribute progIdAttributeObj = (ProgIdAttribute)attributes[typeof(ProgIdAttribute)]; Console.WriteLine("ProgIdAttribute's value is set to : " + progIdAttributeObj.Value); } catch(Exception e) { Console.WriteLine("Exception : " + e.Message); } } }
