MessageBuffer.WriteMessage(Stream) 方法

定義

命名空間:

System.ServiceModel.Channels

組件:

System.ServiceModel.Primitives.dll

組件:

System.ServiceModel.dll

將這個緩衝區的整個內容寫入指定的 IO 資料流。

public:
 virtual void WriteMessage(System::IO::Stream ^ stream);

public virtual void WriteMessage (System.IO.Stream stream);

abstract member WriteMessage : System.IO.Stream -> unit
override this.WriteMessage : System.IO.Stream -> unit

Public Overridable Sub WriteMessage (stream As Stream)

參數

stream

Stream

在其中寫入這個緩衝區整個內容的 IO 資料流。

範例

private byte[] ConvertMessageToByteArray(ref Message message)   
{  
    // Memory stream that contains the message.
    var stream = new MemoryStream();  
    // Create an XmlWriter to serialize the message into a byte array.
    var settings = new XmlWriterSettings();
    settings.Encoding = System.Text.Encoding.UTF8;
    XmlWriter writer = XmlWriter.Create(stream, settings);
    // Copy the message into a buffer.
    // Note: This call changes the original message's state.
    MessageBuffer buffer = message.CreateBufferedCopy(int.MaxValue);  
    // Create a copy of the message.
    message = buffer.CreateMessage();  
    // Serialize the message to the XmlWriter.
    message.WriteMessage(writer);  
    // Recreate the message.
    message = buffer.CreateMessage();
    // Flush the contents of the writer so that the stream gets updated.
    writer.Flush();  
    stream.Flush();  
    // Convert the stream to an array.
    byte[] retval = stream.ToArray();
    return retval;
}  

備註

這個功能會使用二進位編碼器取代 UTF-8 編碼器。 因此，您無法從 MessageBuffer 直接轉換至 Message。 ＜範例＞一節中的程式碼會示範如何解決這個問題。
