今日配置web.config
public bool appSettingsEdit(string WebConfigDirectory,string appSettingsAddkey,string keyvalue)
{
try
{
string path=WebConfigDirectory+"\\web.config";
XmlDocument xd=new XmlDocument();
xd.Load(path);
//如果没有appSetting,则添加
if(xd.SelectNodes("//appSettings").Count==0)
{
xd.DocumentElement.AppendChild(xd.CreateElement("appSettings"));
}
//判断节点是否存在,如果存在则修改当前节点
bool addNode=true;
foreach(XmlNode xn1 in xd.SelectNodes("/configuration/appSettings/add"))
{
if(xn1.Attributes["key"].Value==appSettingsAddkey)
{
addNode=false;
xn1.Attributes["value"].Value=keyvalue;
// xn1.ParentNode.RemoveChild(xn1);
break;
}
}
//当前节点不存在,则添加新节点
if(addNode)
{
//创建新节点
XmlNode xn2=xd.CreateElement("add");
//添加key
XmlAttribute xa=xd.CreateAttribute("key");
xa.Value=appSettingsAddkey;
xn2.Attributes.Append(xa);
//添加value
xa=xd.CreateAttribute("value");
xa.Value=keyvalue;
xn2.Attributes.Append(xa);
xd.SelectSingleNode("/configuration/appSettings").AppendChild(xn2);
}
//保存web.config
xd.Save(path);
return true;
}
catch
{
return false;
}
}
