流的奇怪问题

你应该能够找到一个 MemoryStream 没有问题:

private static string GetContents(TransactionResults t)
{
    XmlSerializer s = new XmlSerializer(typeof(TransactionResults));
    MemoryStream stream = new MemoryStream();
    s.Serialize(stream, t);
    stream.Position = 0; // Rewind to the beginning of the stream
    return new StreamReader(stream).ReadToEnd();
}

内存流 首先-然后你可以随时倒带。

我发现有这样一种方法很有用,可以将一个流耗尽,然后写入另一个流:

public static void CopyStream(Stream input, Stream output)
{
    byte[] buffer = new byte[8 * 1024];
    int len;
    while ( (len = input.Read(buffer, 0, buffer.Length)) > 0)
    {
        output.Write(buffer, 0, len);
    }    
}

内存流

将流读入内存流并对其进行操作,它支持查找。

public static string ToXmlString(object xmlObject)
{
    if (xmlObject == null)
        throw new NullReferenceException("xmlObject cannot be null.");

    String xmlResult = null;

    XmlSerializer serializer = new XmlSerializer(xmlObject.GetType());
    using (StringWriter writer = new StringWriter())
    {
        serializer.Serialize(writer, xmlObject);
        xmlResult = writer.ToString();
    }

    return xmlResult;
}
