读取XML文件

XmlDocument xmlDoc = new XmlDocument();
string filePath = Path.Combine(AppContext.BaseDirectory, "Configuration", sDir, string.Format("{0}.xml", sXmlName));

StringBuilder builder = new StringBuilder();
using (FileStream fs = File.Open(filePath, FileMode.OpenOrCreate))
{
using (StreamReader sr = new StreamReader(fs, Encoding.UTF8))
{

builder.Append(sr.ReadToEnd());
}
}
if (builder.Length > 0)
xmlDoc.LoadXml(builder.ToString());      //
return xmlDoc;

注意：

xmldoc.load可以加载文件，比如：xmldoc.load("c:\\a.xml");
而xmldoc.loadXML是加载xml格式的字符串，比如：xmldoc.loadXML("<aab>aaa</aab>")
