HttpListenerRequest.ContentEncoding 屬性

定義

取得可用於隨要求所傳送資料的內容編碼方式。

public:
 property System::Text::Encoding ^ ContentEncoding { System::Text::Encoding ^ get(); };
public System.Text.Encoding ContentEncoding { get; }
member this.ContentEncoding : System.Text.Encoding
Public ReadOnly Property ContentEncoding As Encoding

屬性值

Encoding 物件,適用於 InputStream 屬性中的資料。

範例

下列程式代碼範例示範如何使用 ContentEncoding 屬性。

public static void ShowRequestData (HttpListenerRequest request)
{
    if (!request.HasEntityBody)
    {
        Console.WriteLine("No client data was sent with the request.");
        return;
    }
    System.IO.Stream body = request.InputStream;
    System.Text.Encoding encoding = request.ContentEncoding;
    System.IO.StreamReader reader = new System.IO.StreamReader(body, encoding);
    if (request.ContentType != null)
    {
        Console.WriteLine("Client data content type {0}", request.ContentType);
    }
    Console.WriteLine("Client data content length {0}", request.ContentLength64);

    Console.WriteLine("Start of client data:");
    // Convert the data to a string and display it on the console.
    string s = reader.ReadToEnd();
    Console.WriteLine(s);
    Console.WriteLine("End of client data:");
    body.Close();
    reader.Close();
    // If you are finished with the request, it should be closed also.
}
Public Shared Sub ShowRequestData(ByVal request As HttpListenerRequest)
    If Not request.HasEntityBody Then
        Console.WriteLine("No client data was sent with the request.")
        Return
    End If

    Dim body As System.IO.Stream = request.InputStream
    Dim encoding As System.Text.Encoding = request.ContentEncoding
    Dim reader As System.IO.StreamReader = New System.IO.StreamReader(body, encoding)

    If request.ContentType IsNot Nothing Then
        Console.WriteLine("Client data content type {0}", request.ContentType)
    End If

    Console.WriteLine("Client data content length {0}", request.ContentLength64)
    Console.WriteLine("Start of client data:")
    ' Convert the data to a string and display it on the console.
    Dim s As String = reader.ReadToEnd()
    Console.WriteLine(s)
    Console.WriteLine("End of client data:")
    body.Close()
    reader.Close()
    ' If you are finished with the request, it should be closed also.
End Sub

備註

Encoding物件可用來將位元組序列轉換成字元集, (代碼頁) 和字元轉換成位元組序列。 這個屬性會使用標頭中的 Content-Type charset 值來判斷編碼方式。 如果此資訊無法使用,這個屬性會傳 Encoding.Default回 。
