AutoCompleteAttribute 类

定义

将特性化方法标记为 AutoComplete 对象。Marks the attributed method as an AutoComplete object. 此类不能被继承。This class cannot be inherited.

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

示例

下面的代码示例演示如何使用AutoCompleteAttribute类型。The following code example demonstrates the use of the AutoCompleteAttribute type.

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

// References:
// System.EnterpriseServices

public class AutoCompleteAttribute_Example : ServicedComponent
{
    [AutoComplete]
    public void AutoCompleteAttribute_Ctor()
    {
    }

    [AutoComplete(true)]
    public void AutoCompleteAttribute_Ctor_Bool()
    {
    }

    [AutoComplete(false)]
    public void AutoCompleteAttribute_Value()
    {
        // Get information on the member.
        System.Reflection.MemberInfo[] memberinfo = 
            this.GetType().GetMember(
            "AutoCompleteAttribute_Value");

        // Get the AutoCompleteAttribute applied to the member.
        AutoCompleteAttribute attribute =
            (AutoCompleteAttribute)System.Attribute.GetCustomAttribute(
            memberinfo[0],
            typeof(AutoCompleteAttribute),
            false);

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

Imports System.EnterpriseServices
Imports System.Reflection


' References:
' System.EnterpriseServices

Public Class AutoCompleteAttribute_Example
    Inherits ServicedComponent
    
    <AutoComplete()>  _
    Public Sub AutoCompleteAttribute_Ctor() 
    
    End Sub

    <AutoComplete(True)>  _
    Public Sub AutoCompleteAttribute_Ctor_Bool() 
    
    End Sub

    <AutoComplete(False)>  _
    Public Sub AutoCompleteAttribute_Value() 
        ' Get information on the member.
        Dim memberinfo As System.Reflection.MemberInfo() = Me.GetType().GetMember("AutoCompleteAttribute_Value")
        
        ' Get the AutoCompleteAttribute applied to the member.
        Dim attribute As AutoCompleteAttribute = CType(System.Attribute.GetCustomAttribute(memberinfo(0), GetType(AutoCompleteAttribute), False), AutoCompleteAttribute)
        
        ' Display the value of the attribute's Value property.
        MsgBox("AutoCompleteAttribute.Value: " & attribute.Value)
    
    End Sub

End Class

注解

如果AutoComplete指定了, 则不能在 com + 目录中禁用它; 如果在 com + 目录中启用了此功能, 则必须在组件上指定它。If AutoComplete is specified, it must not be disabled in the COM+ catalog; if enabled in the COM+ catalog, it must be specified on the component.

如果方法调用正常SetComplete返回, 则事务会自动调用。The transaction automatically calls SetComplete if the method call returns normally. 如果方法调用引发异常, 则事务将中止。If the method call throws an exception, the transaction is aborted.

构造函数

AutoCompleteAttribute()

初始化 AutoCompleteAttribute 类的新实例,并指定如果事务成功完成应用程序应自动调用 SetComplete()Initializes a new instance of the AutoCompleteAttribute class, specifying that the application should automatically call SetComplete() if the transaction completes successfully.

AutoCompleteAttribute(Boolean)

初始化 AutoCompleteAttribute 类的新实例,并指定是否启用 COM+ AutoCompleteInitializes a new instance of the AutoCompleteAttribute class, specifying whether COM+ AutoComplete is enabled.

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

获取一个值,该值指示 COM+ 中 AutoComplete 选项的设置。Gets a value indicating the setting of the AutoComplete option in COM+.

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.
