private void Decompress(string file)
        {
            FileInfo fi = new FileInfo(file);

            // Get the stream of the source file.
            using (FileStream inFile = fi.OpenRead())
            {
                // Get original file extension, for example
                // "doc" from report.doc.gz.
                string curFile = fi.FullName;
                string origName = curFile.Remove(curFile.Length -
                        fi.Extension.Length);

                //Create the decompressed file.
                using (FileStream outFile = System.IO.File.Create(origName))
                {
                    using (GZipStream Decompress = new GZipStream(inFile,
                            CompressionMode.Decompress))
                    {
                        // Copy the decompression stream
                        // into the output file.
                        <big>Decompress.CopyTo(outFile);</big>                    }
                }
            }

推荐答案

您是否已包含以下命名空间: System.IO.Compression

我看到您已经复制粘贴了此处提供的示例: http://msdn.microsoft.com/zh-我们/library/ms404280.aspx [ ^ ]

如果您注意到，上面的代码中的Decompress对象是 GZipStream类的对象 [^ ].它确实具有公开的属性CopyTo: MSDN:Stream.CopyTo方法(流) [ ^ ]，它从当前流中读取字节，并将它们写入目标流.

确保您有完整的程序要执行.

Have you included this namespace: System.IO.Compression

I see you have copy-pasted the sample given here: http://msdn.microsoft.com/en-us/library/ms404280.aspx[^]

If you notice, Decompress object in the code above is an object of GZipStream Class[^]. It does have a property CopyTo exposed: MSDN: Stream.CopyTo Method (Stream)[^] that reads the bytes from the current stream and writes them to the destination stream.

Make sure you have a complete program to execute.
