ApplicationIDAttribute 类

定义

为该程序集指定应用程序 ID(作为 GUID)。Specifies the application ID (as a GUID) for this assembly. 此类不能被继承。This class cannot be inherited.

public ref class ApplicationIDAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Assembly, Inherited=true)]
[System.Runtime.InteropServices.ComVisible(false)]
public sealed class ApplicationIDAttribute : Attribute
type ApplicationIDAttribute = class
    inherit Attribute
Public NotInheritable Class ApplicationIDAttribute
Inherits Attribute
继承
ApplicationIDAttribute
属性

示例

下面的代码示例演示如何使用ApplicationIDAttribute类型。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);
    }
}

Imports System.EnterpriseServices
Imports 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
    Inherits ServicedComponent
    
    Public Sub ValueExample() 
        ' Get the ApplicationIDAttribute applied to the assembly.
        Dim attribute As ApplicationIDAttribute = CType(Attribute.GetCustomAttribute(System.Reflection.Assembly.GetExecutingAssembly(), GetType(ApplicationIDAttribute), False), ApplicationIDAttribute)
        
        ' Display the value of the attribute's Value property.
        MsgBox("ApplicationIDAttribute.Value: " & attribute.Value.ToString())

    End Sub
End Class

注解

ApplicationIDAttribute在其构造函数中使用 GUID。ApplicationIDAttribute takes a GUID in its constructor. 进行注册时, 程序集中的组件将安装在具有给定 ID 的应用程序中。When registration occurs, the components in the assembly are installed in an application with the given ID.

构造函数

ApplicationIDAttribute(String)

初始化 ApplicationIDAttribute 类的新实例,该类指定表示 COM+ 应用程序的应用程序 ID 的 GUID。Initializes a new instance of the ApplicationIDAttribute class specifying the GUID representing the application ID for the COM+ application.

属性

TypeId

在派生类中实现时,获取此 Attribute 的唯一标识符。When implemented in a derived class, gets a unique identifier for this Attribute.

(继承自 Attribute)
Value

获取 COM+ 应用程序的 GUID。Gets the GUID of the COM+ application.

方法

Equals(Object)

返回一个值,该值指示此实例是否与指定的对象相等。Returns a value that indicates whether this instance is equal to a specified object.

(继承自 Attribute)
GetHashCode()

返回此实例的哈希代码。Returns the hash code for this instance.

(继承自 Attribute)
GetType()

获取当前实例的 TypeGets the Type of the current instance.

(继承自 Object)
IsDefaultAttribute()

在派生类中重写时,指示此实例的值是否是派生类的默认值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(继承自 Attribute)
Match(Object)

当在派生类中重写时,返回一个指示此实例是否等于指定对象的值。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(继承自 Attribute)
MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
ToString()

返回表示当前对象的字符串。Returns a string that represents the current object.

(继承自 Object)

显式接口实现

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

将一组名称映射为对应的一组调度标识符。Maps a set of names to a corresponding set of dispatch identifiers.

(继承自 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

检索对象的类型信息,然后可以使用该信息获取接口的类型信息。Retrieves the type information for an object, which can be used to get the type information for an interface.

(继承自 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

检索对象提供的类型信息接口的数量(0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(继承自 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

提供对某一对象公开的属性和方法的访问。Provides access to properties and methods exposed by an object.

(继承自 Attribute)
