ServicePoint.ConnectionLimit 属性

定义

命名空间:

System.Net

程序集:

System.Net.ServicePoint.dll

Source:

ServicePoint.cs

获取或设置此 ServicePoint 对象上允许的最大连接数。

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

public int ConnectionLimit { get; set; }

member this.ConnectionLimit : int with get, set

Public Property ConnectionLimit As Integer

属性值

Int32

此 ServicePoint 对象允许的最大连接数。

例外

ArgumentOutOfRangeException

连接限制等于或小于 0。

示例

下面的代码示例使用 ConnectionLimit 属性来检查 ServicePoint 对象可以连接到指定的统一资源标识符（URI）的最大连接数。

Console::WriteLine( "ConnectionName = {0}", sp->ConnectionName );

// Display the maximum number of connections allowed on this 
// ServicePoint instance.
Console::WriteLine( "ConnectionLimit = {0}", sp->ConnectionLimit );

// Display the number of connections associated with this 
// ServicePoint instance.
Console::WriteLine( "CurrentConnections = {0}", sp->CurrentConnections );

Console.WriteLine("ConnectionName = " + sp.ConnectionName);

// Display the maximum number of connections allowed on this
// ServicePoint instance.
Console.WriteLine("ConnectionLimit = " + sp.ConnectionLimit);

// Display the number of connections associated with this
// ServicePoint instance.
Console.WriteLine("CurrentConnections = " + sp.CurrentConnections);

Console.WriteLine(("ConnectionName = " + sp.ConnectionName))

' Display the maximum number of connections allowed on this 
' ServicePoint instance.
Console.WriteLine(("ConnectionLimit = " + sp.ConnectionLimit.ToString()))

' Display the number of connections associated with this 
' ServicePoint instance.
Console.WriteLine(("CurrentConnections = " + sp.CurrentConnections.ToString()))

注解

谨慎

WebRequest、HttpWebRequest、ServicePoint和 WebClient 已过时，不应将其用于新开发。 请改用 HttpClient。

ConnectionLimit 属性设置 ServicePoint 对象可以连接到 Internet 资源的最大连接数。 创建 ServicePoint 对象时，ConnectionLimit 属性的值设置为 ServicePointManager.DefaultConnectionLimit 属性的值;对 DefaultConnectionLimit 的后续更改对现有 ServicePoint 对象没有影响。
