Specifies the application ID (as a GUID) for this assembly. This class cannot be inherited.

System.Object
  System.Attribute
    System.EnterpriseServices.ApplicationIDAttribute

Namespace:  System.EnterpriseServices
Assembly:  System.EnterpriseServices (in System.EnterpriseServices.dll)

[AttributeUsageAttribute(AttributeTargets.Assembly, Inherited = true)]
[ComVisibleAttribute(false)]
public sealed class ApplicationIDAttribute : Attribute

The ApplicationIDAttribute type exposes the following members.

  NameDescription
Public methodApplicationIDAttributeInitializes a new instance of the ApplicationIDAttribute class specifying the GUID representing the application ID for the COM+ application.
Top

  NameDescription
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Public propertyValueGets the GUID of the COM+ application.
Top

  NameDescription
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

ApplicationIDAttribute takes a GUID in its constructor. When registration occurs, the components in the assembly are installed in an application with the given ID.

The following code example demonstrates the use of the ApplicationIDAttribute type.

using System;
using System.EnterpriseServices;
using System.Reflection;

// References: 
// System.EnterpriseServices 

// The GUID (Globally Unique Identifier) shown below is for example purposes 
// only and should be replaced by a GUID that you have generated.
[assembly: ApplicationID("727FC170-1D80-4e89-84CC-22AAB10A6F24")]

public class ApplicationIDAttribute_Value : ServicedComponent
{
    public void ValueExample()
    {
        // Get the ApplicationIDAttribute applied to the assembly.
        ApplicationIDAttribute attribute =
            (ApplicationIDAttribute)Attribute.GetCustomAttribute(
            System.Reflection.Assembly.GetExecutingAssembly(),
            typeof(ApplicationIDAttribute),
            false);

        // Display the value of the attribute's Value property.
        Console.WriteLine("ApplicationIDAttribute.Value: {0}",
            attribute.Value);
    }
}
