本文介绍了一种使用C#将图片文件转换为十六进制并写入XML的方法。通过具体的代码实例，展示了如何设置XML文件格式、写入图片文件的元数据及二进制数据。

1 protected void Page_Load(object sender, EventArgs e)
2     {
3         XmlWriterSettings settings = new XmlWriterSettings();
4         settings.Indent = true;
5         settings.IndentChars = "\t";
6         settings.OmitXmlDeclaration = false;
7
8         using (XmlWriter writer = XmlWriter.Create(Server.MapPath("WriteXmlImage.xml"), settings))
9         {
10             string imgFileName = Server.MapPath("image/img01.jpg");
11
12             writer.WriteStartDocument(false);
13             writer.WriteComment("This is my first image xml.");
14             writer.WriteStartElement("exployee"); writer.WriteAttributeString("id", "1");
15                 writer.WriteStartElement("image"); writer.WriteAttributeString("filename", imgFileName);
16                     FileInfo fileInfo = new FileInfo(imgFileName);
17                     int size = (int)fileInfo.Length;
18                     byte[] imgBytes = new byte[size];
19                     FileStream imgFileStream = new FileStream(imgFileName, FileMode.Open);
20                     BinaryReader binaryReader = new BinaryReader(imgFileStream);
21                     imgBytes = binaryReader.ReadBytes(size);
22                     binaryReader.Close();
23
24                     writer.WriteBinHex(imgBytes, 0, size);
25
26                 writer.WriteEndElement();
27             writer.WriteEndElement();
28         }
29     }

输出结果：

1 <?xml version="1.0" encoding="utf-8" standalone="no"?>
2 
3 <exployee id="1">
4     <image filename="E:\AspXml\image\img01.jpg">
5                FFD8FFE000104A4649460001..........
6         </image>
7 </exployee>
