C# xml的读取及图像信息的读取

如何读取Xml文件中节点及属性值。以及根据xml节点的文件二进制流保存为文件

定义xml文件的路径

string XMLFileName = Application.StartupPath + "\\Data\\Data.xml";

XmlDocument doc = new XmlDocument();

doc.Load(XMLFileName);

XmlNodeList DocNode = doc.DocumentElement.ChildNodes;

foreach (XmlElement images in DocNode) //查询所有一级子节点

{

if (images.Name.ToLower() == "images")

{

foreach (XmlElement image in images)//查询二级子节点

{

if (image.Name.ToLower() == "image")

{

string f = image.InnerText;//值的赋值

string FName = image.GetAttribute("Name").ToString();//属性的赋值

string SizeS = image.GetAttribute("Size").ToString();

if (!Directory.Exists(Application.StartupPath + "\\ImageData"))//判断文件夹是否存在

{

Directory.CreateDirectory(Application.StartupPath + "\\ImageData");

}



byte[] file = null;

byte[] b = Convert.FromBase64String(f);

file = (byte[])b;

FileStream fs;

FileInfo fi = new System.IO.FileInfo(Application.StartupPath + "\\ImageData\\" + FName.ToString().Trim());

fs = fi.OpenWrite();

fs.Write(file, 0, file.Length);

if (!(SizeS == fs.Length.ToString()))

{

MessageBox.Show("文件保存出错！" + fs.Name.ToString());

}

fs.Close();



}

}

}

}

}
