HttpListener.Prefixes 属性

定义

获取由此 HttpListener 对象处理的统一资源标识符 (URI) 前缀。Gets the Uniform Resource Identifier (URI) prefixes handled by this HttpListener object.

public:
 property System::Net::HttpListenerPrefixCollection ^ Prefixes { System::Net::HttpListenerPrefixCollection ^ get(); };
public System.Net.HttpListenerPrefixCollection Prefixes { get; }
member this.Prefixes : System.Net.HttpListenerPrefixCollection
Public ReadOnly Property Prefixes As HttpListenerPrefixCollection

属性值

HttpListenerPrefixCollection,包含此 HttpListener 对象在经配置后要处理的 URI 前缀。An HttpListenerPrefixCollection that contains the URI prefixes that this HttpListener object is configured to handle.

例外

此对象已关闭。This object has been closed.

示例

下面的代码示例演示如何使用 Prefixes 属性来获取和打印处理的 URI 前缀。The following code example demonstrates using the Prefixes property to obtain and print the URI prefixes that are handled.

public static void DisplayPrefixesAndState(HttpListener listener)
{
    // List the prefixes to which the server listens.
    HttpListenerPrefixCollection prefixes = listener.Prefixes;
    if (prefixes.Count == 0)
    {
        Console.WriteLine("There are no prefixes.");
    }
    foreach(string prefix in prefixes)
    {
        Console.WriteLine(prefix);
    }
    // Show the listening state.
    if (listener.IsListening)
    {
        Console.WriteLine("The server is listening.");
    }
}
Public Shared Sub DisplayPrefixesAndState(ByVal listener As HttpListener)
    ' List the prefixes to which the server listens.
    Dim prefixes As HttpListenerPrefixCollection = listener.Prefixes

    If prefixes.Count = 0 Then
        Console.WriteLine("There are no prefixes.")
    End If

    For Each prefix As String In prefixes
        Console.WriteLine(prefix)
    Next

    ' Show the listening state.
    If listener.IsListening Then
        Console.WriteLine("The server is listening.")
    End If
End Sub

注解

前缀采用规范格式。The prefixes are in canonical form. 有关前缀的详细说明,请参阅 HttpListener 类概述。For a detailed description of prefixes, see the HttpListener class overview.
