随便写写的一个例子：
//
保存图片到 XML 文件
private
void
Form1_Load(
object
sender, System.EventArgs e)
{
Image img = Image.FromFile(@"E:\MyDocs\My Pictures\样品.jpg");
System.IO.MemoryStream stream = new System.IO.MemoryStream();
img.Save(stream, ImageFormat.Jpeg);
byte[] b = stream.GetBuffer();
string s = Convert.ToBase64String(b);
XmlDocument doc = new XmlDocument();
doc.AppendChild(doc.CreateElement("image"));
XmlElement elmtData = doc.CreateElement("data");
elmtData.InnerText = s;
doc.DocumentElement.AppendChild(elmtData);
doc.Save("test.xml");
}
//
从 XML 文件中读取图片信息
private
void
button1_Click(
object
sender, System.EventArgs e)
{
XmlDocument doc = new XmlDocument();
doc.Load("test.xml");
string s = doc.DocumentElement.SelectSingleNode("data").InnerText;
byte[] b = Convert.FromBase64String(s);
MemoryStream stream = new MemoryStream(b);
Bitmap bitmap = new Bitmap(stream);
this.pictureBox1.Image = bitmap;
}
//
保存图片到 XML 文件
private
void
Form1_Load(
object
sender, System.EventArgs e)
{
Image img = Image.FromFile(@"E:\MyDocs\My Pictures\样品.jpg"); System.IO.MemoryStream stream = new System.IO.MemoryStream(); img.Save(stream, ImageFormat.Jpeg); byte[] b = stream.GetBuffer(); string s = Convert.ToBase64String(b); XmlDocument doc = new XmlDocument(); doc.AppendChild(doc.CreateElement("image")); XmlElement elmtData = doc.CreateElement("data"); elmtData.InnerText = s; doc.DocumentElement.AppendChild(elmtData); doc.Save("test.xml"); }
//

void
button1_Click(

sender, System.EventArgs e)
{ XmlDocument doc = new XmlDocument(); doc.Load("test.xml"); string s = doc.DocumentElement.SelectSingleNode("data").InnerText; byte[] b = Convert.FromBase64String(s); MemoryStream stream = new MemoryStream(b); Bitmap bitmap = new Bitmap(stream); this.pictureBox1.Image = bitmap; }
