XPS和字节流互转

1、XPS转字节流

方法一：

byte[] xpsBytes = File.ReadAllBytes(@"E:\\代码测试区\\WPF XPS\\XPSSave练习\\WpfApplication1\\WpfApplication1\\content\\3.xps");

方法二：

string url=@"E:\\代码测试区\\WPF XPS\\XPSSave练习\\WpfApplication1\\WpfApplication1\\content\\3.xps";
var webClient = new System.Net.WebClient();
byte[] data = webClient.DownloadData(url);

2、字节流转XPSDocument

public static XpsDocument OpenXpsDocument(string url)
{
    var webClient = new WebClient();
    var data = webClient.DownloadData(url);
    var package = System.IO.Packaging.Package.Open(new MemoryStream(data));
    var xpsDocument = new XpsDocument(package, 
                                      CompressionOption.SuperFast, 
                                      url);
    return xpsDocument;
}

 

3、字节流生成XPS文件

        public static void OpenXpsDocument(string url)
        {
            var webClient = new System.Net.WebClient();
            byte[] data = webClient.DownloadData(url);

            string fileName = Guid.NewGuid().ToString();
            string xpsTempFilePath = string.Format("{0}\\" + fileName + ".xps", Environment.CurrentDirectory);
            using (BinaryWriter writer = new System.IO.BinaryWriter(File.OpenWrite(xpsTempFilePath)))
            {
                writer.Write(data);
                writer.Flush();
            }

            //XpsDocument xpsDocument = new System.Windows.Xps.Packaging.XpsDocument(xpsTempFilePath, FileAccess.Read);
            //return xpsDocument;
        }
