Answer 1

试试这个        test(Server.MapPath("~/xml/yecuiInfo.xml"));
        private void test(string xmlpath)
        {
            XmlDocument indexXml = new XmlDocument();
            indexXml.Load(xmlpath);            XmlNode item = indexXml.SelectSingleNode("yecuiInfo");            item.SelectSingleNode("name").InnerText = "test";
            indexXml.Save(xmlpath);            
        }

Answer 2

DataTable dt = null;
DataRow dr = null;
System.IO.StringWriter writer = null;
StreamWriter sw = null;
dt = new DataTable("ProgramTable");
dt.Columns.Add("Height", Type.GetType("System.String"));
dt.Columns.Add("Width", Type.GetType("System.String"));
dt.Columns.Add("SavePath", Type.GetType("System.String"));
dt.Columns.Add("ProgramName", Type.GetType("System.String"));
dt.Columns.Add("ProgramType", Type.GetType("System.String"));
dt.Columns.Add("IpAdder", Type.GetType("System.String"));
dt.Columns.Add("Port", Type.GetType("System.String"));
dr = dt.NewRow();
dr["Height"] = progectProperty.ScreenHeight.ToString();
dr["Width"] = progectProperty.ScreenWidth.ToString();
dr["SavePath"] = progectProperty.SavePath;
dr["ProgramName"] = progectProperty.ProgramName;
dr["ProgramType"] = progectProperty.ProgramType;
dr["IpAdder"] = progectProperty.IpAdder;
dr["Port"] = progectProperty.Prot.ToString();
dt.Rows.Add(dr);
writer = new StringWriter();
writer.WriteLine("<?xml version=\"1.0\" encoding=\"utf-8\"?>");//可以把这个去掉试试
dt.WriteXml(writer);
sw = new StreamWriter(progectProperty.SavePath + "\\Main.xml");
sw.WriteLine(writer);
sw.Close();
