HttpListenerResponse.ContentLength64 속성

정의

응답에 포함된 본문 데이터의 바이트 수를 가져오거나 설정합니다.Gets or sets the number of bytes in the body data included in the response.

public:
 property long ContentLength64 { long get(); void set(long value); };
public long ContentLength64 { get; set; }
member this.ContentLength64 : int64 with get, set
Public Property ContentLength64 As Long

속성 값

응답의 Content-Length 헤더 값입니다.The value of the response's Content-Length header.

예외

set 작업에 지정된 값이 0보다 작은 경우The value specified for a set operation is less than zero.

응답을 이미 보내고 있는 경우The response is already being sent.

이 개체가 닫혀 있는 경우This object is closed.

예제

다음 코드 예제에서는이 속성의 값을 설정 하는 방법을 보여 줍니다.The following code example demonstrates setting the value of this property.

// This example requires the System and System.Net namespaces.
public static void SimpleListenerExample(string[] prefixes)
{
    if (!HttpListener.IsSupported)
    {
        Console.WriteLine ("Windows XP SP2 or Server 2003 is required to use the HttpListener class.");
        return;
    }
    // URI prefixes are required,
    // for example "http://contoso.com:8080/index/".
    if (prefixes == null || prefixes.Length == 0)
      throw new ArgumentException("prefixes");
    
    // Create a listener.
    HttpListener listener = new HttpListener();
    // Add the prefixes.
    foreach (string s in prefixes)
    {
        listener.Prefixes.Add(s);
    }
    listener.Start();
    Console.WriteLine("Listening...");
    // Note: The GetContext method blocks while waiting for a request. 
    HttpListenerContext context = listener.GetContext();
    HttpListenerRequest request = context.Request;
    // Obtain a response object.
    HttpListenerResponse response = context.Response;
    // Construct a response.
    string responseString = "<HTML><BODY> Hello world!</BODY></HTML>";
    byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString);
    // Get a response stream and write the response to it.
    response.ContentLength64 = buffer.Length;
    System.IO.Stream output = response.OutputStream;
    output.Write(buffer,0,buffer.Length);
    // You must close the output stream.
    output.Close();
    listener.Stop();
}
Public Shared Sub SimpleListenerExample(prefixes As String())
    If Not HttpListener.IsSupported Then
        Console.WriteLine("Windows XP SP2 or Server 2003 is required to use the HttpListener class.")
        Return
    End If
    ' URI prefixes are required,
    ' for example "http://contoso.com:8080/index/".
    If prefixes Is Nothing Or prefixes.Length = 0 Then
        Throw New ArgumentException("prefixes")
    End If

    ' Create a listener
    Dim listener = New HttpListener()

    For Each s As String In prefixes
        listener.Prefixes.Add(s)
    Next
    listener.Start()
    Console.WriteLine("Listening...")
    ' Note: The GetContext method blocks while waiting for a request.
    Dim context As HttpListenerContext = listener.GetContext()
    Console.WriteLine("Listening...")
    ' Obtain a response object
    Dim request As HttpListenerRequest = context.Request
    ' Construct a response.
    Dim response As HttpListenerResponse = context.Response
    Dim responseString As String = "<HTML><BODY> Hello world!</BODY></HTML>"
    Dim buffer As Byte() = System.Text.Encoding.UTF8.GetBytes(responseString)
    ' Get a response stream and write the response to it.
    response.ContentLength64 = buffer.Length
    Dim output As System.IO.Stream = response.OutputStream
    output.Write(buffer, 0, buffer.Length)
    'You must close the output stream.
    output.Close()
    listener.Stop()
End Sub

설명

Content-Length 헤더는 응답 본문 데이터의 길이 (바이트)를 나타냅니다.The Content-Length header expresses the length, in bytes, of the response's body data. 데이터 청크 또는 원시 데이터를 보내지 않는 형식을 사용 하는 경우 ContentLength64 속성을 설정 해야 합니다.When using a format that does not send the data chunked or raw, you must set the ContentLength64 property. 그렇지 않으면 HttpListener 응답 데이터를 전송 하지 않습니다.If you do not, the HttpListener does not send the response data.

응답 헤더의 전체 목록은 HttpResponseHeader 열거를 참조 하세요.For a complete list of response headers, see the HttpResponseHeader enumeration.
