ApplicationQueuingAttribute.MaxListenerThreads Property

Definition

Gets or sets the number of threads used to extract messages from the queue and activate the corresponding component.

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

Property Value

The maximum number of threads to use for processing messages arriving in the queue. The default is zero.

Examples

The following code example gets and sets the value of an ApplicationQueuing attribute's MaxListenerThreads property.

// 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)

Remarks

The valid range for this property is 0 to 1000. The default is zero. For a newly created application, the setting is derived from the algorithm currently used for determining the default number of listener threads: 16 times the number of CPUs in the server.
