ApplicationQueuingAttribute.MaxListenerThreads 属性

定义

命名空间:

System.EnterpriseServices

程序集:

System.EnterpriseServices.dll

获取或设置用于从队列提取消息并激活相应组件的线程的数目。

public:
 property int MaxListenerThreads { int get(); void set(int value); };

public int MaxListenerThreads { get; set; }

member this.MaxListenerThreads : int with get, set

Public Property MaxListenerThreads As Integer

属性值

Int32

用于处理到达队列中的消息的线程的最大数目。 默认值为零。

示例

下面的代码示例获取并设置特性的 MaxListenerThreads 属性的值ApplicationQueuing。

// This example code requires that an ApplicationQueuing attribute be
// applied to the assembly, as shown below:
// [assembly: ApplicationQueuing]

// Get the ApplicationQueuingAttribute applied to the assembly.
ApplicationQueuingAttribute attribute =
    (ApplicationQueuingAttribute)Attribute.GetCustomAttribute(
    System.Reflection.Assembly.GetExecutingAssembly(),
    typeof(ApplicationQueuingAttribute),
    false);

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

// Set the MaxListenerThreads property value of the attribute.
attribute.MaxListenerThreads = 1;

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

' This example code requires that an ApplicationQueuing attribute be
' applied to the assembly, as shown below:
' [assembly: ApplicationQueuing]
' Get the ApplicationQueuingAttribute applied to the assembly.
Dim attribute As ApplicationQueuingAttribute = CType(attribute.GetCustomAttribute(System.Reflection.Assembly.GetExecutingAssembly(), GetType(ApplicationQueuingAttribute), False), ApplicationQueuingAttribute)

' Display the current value of the attribute's MaxListenerThreads
' property.
MsgBox("ApplicationQueuingAttribute.MaxListenerThreads: " & attribute.MaxListenerThreads)

' Set the MaxListenerThreads property value of the attribute.
attribute.MaxListenerThreads = 1

' Display the new value of the attribute's MaxListenerThreads
' property.
MsgBox("ApplicationQueuingAttribute.MaxListenerThreads: " & attribute.MaxListenerThreads)

注解

此属性的有效范围是 0 到 1000。 默认值为零。 对于新创建的应用程序，设置派生自当前用于确定默认侦听器线程数的算法：服务器中 CPU 数的 16 倍。
