C# 使用gzipstream将压缩的xml数据写入内存流

我试图将压缩的xml数据写入内存流。以下是我的测试控制台应用程序代码：

var ms = new MemoryStream();
var gstream = new GZipStream(ms, CompressionMode.Compress);

var settings = new XmlWriterSettings();
settings.Indent = true;

var writer = XmlWriter.Create(gstream, settings);
writer.WriteStartElement("x", "root", "123");
writer.WriteStartElement("item");
writer.WriteAttributeString("xmlns", "x", null, "abc");
writer.WriteEndElement();
writer.WriteEndElement();            

Console.WriteLine("Data length: " + ms.ToArray().Length);

writer.Close();
gstream.Close();
ms.Close();    

Console.ReadLine();

输出为：

Data length: 0

我做错了什么？谢谢。

您必须关闭写入程序才能刷新流。只需将代码更改为：

writer.Close();
gstream.Close();
ms.Close();   

Console.WriteLine("Data length: " + ms.ToArray().Length);

它应该会起作用
