AutoCompleteAttribute Class

Marks the attributed method as an AutoComplete object. This class cannot be inherited.

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

[AttributeUsageAttribute(AttributeTargets.Method, Inherited = true)]
public sealed class AutoCompleteAttribute : Attribute

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.

The transaction automatically calls SetComplete if the method call returns normally. If the method call throws an exception, the transaction is aborted.

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
    public void AutoCompleteAttribute_Ctor()

    public void AutoCompleteAttribute_Ctor_Bool()

    public void AutoCompleteAttribute_Value()
        // Get information on the member.
        System.Reflection.MemberInfo[] memberinfo = 

        // Get the AutoCompleteAttribute applied to the member.
        AutoCompleteAttribute attribute =

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


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
