使用 c# 将 xml 文件转换为 type="xs:hexBinary"

Question

我正在开发一项服务，我应该将 xml 文件作为字节 [] 提交。我将 xmldocument.outerxml 转换为 byte[]，我还尝试了其他一些 byte[] 转换方法，但没有成功。现在我试图将 xmldocument.outerxml 转换为 type="xs:hexBinary"。谁能帮帮我

提前致谢。

Answer 1

xs:hexBinary 只是字节的十六进制值。以下是您的操作方法：

// Load up some xml
string xml = "<root><child>value</child></root>";

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);

// Get OuterXml as bytes
byte[] bytes = Encoding.UTF8.GetBytes(doc.OuterXml);

// bytes to hex values
StringBuilder buffer = new StringBuilder();

foreach (byte b in bytes)
    buffer.AppendFormat("{0:X2}", b);

// Results
Console.WriteLine(buffer);

更新

发现您需要压缩 Xml 后...要获得 zip 功能，您需要添加对 System.IO.Compression.FileSystem.dll 和 System.IO 的引用.Compression.dll

// Load up some xml
string xml = "<root><child>value</child></root>";

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);


byte[] bytes;

// Create zip
using (MemoryStream ms = new MemoryStream())
{
    using (ZipArchive zip = new ZipArchive(ms, ZipArchiveMode.Create))
    {
        // The name of the xml file inside the zip
        var entry = zip.CreateEntry("myxml_file.xml");
        using (Stream stream = entry.Open())
        {
            // Save the xml file into the zip
            doc.Save(stream);
        }
    }

    // Get bytes of zip file
    bytes = ms.GetBuffer();
}

// Save the file to Debug\Bin\out.zip for testing only (remove from final code)
File.WriteAllBytes("out.zip", bytes);

// bytes to hex values
StringBuilder buffer = new StringBuilder();

foreach (byte b in bytes)
    buffer.AppendFormat("{0:X2}", b);

// Results
Console.WriteLine(buffer);
