修改config配置文件

//需要引用命名空间 using System.Xml;
xmldocument xdc = new xmldocument();
xdc.Load(FrmSelectPath.selectPath + "\FrontInterface.exe.config");
string sqlConnection = "Provider=SQLOLEDB;Data Source="+server+";Initial Catalog="+dbname+";Integrated Security=SSPI;";
foreach(XmlNode xnode in xdc["configuration"]["appSettings"].ChildNodes)
{
string keyStr = xnode.Attributes["key"].Value;
XmlElement xel =(XmlElement)xnode;
if(keyStr=="connString")
{
xel.SetAttribute("value",sqlConnection);
}
if(keyStr == "Interface1" || keyStr == "Interface" || keyStr == "InterfaceRun" )
{
xel.SetAttribute("value",@"tcp://"+Remoting+@"/");
}
}
xdc.Save(FrmSelectPath.selectPath+"\FrontInterface.exe.config");
