MessageBuffer.WriteMessage(Stream) 方法

定义

命名空间:

System.ServiceModel.Channels

程序集:

System.ServiceModel.Primitives.dll

程序集:

System.ServiceModel.dll

将此缓冲区中的整个内容写入指定的 IO 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)

参数

stream

Stream

一个 IO 流，此缓冲区中的整个内容都会写入此 IO 流。

示例

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;
}  

注解

此功能使用的是二进制编码器，而不是 UTF-8 编码器。 因此，无法直接从 MessageBuffer 转换到 Message。 示例部分的代码演示如何解决这个问题。
