我有一个更新配置文件的程序。例如,配置文件可能包含:
<configuration>
<userSettings>
<setting name="phoneNumber" serializeAs="String">
<value>123-456-7890</value>
</setting>
</userSettings>
</configuration>
要更新此配置文件,请使用以下命令:
XmlNode phoneNumberNode = theConfig.SelectSingleNode("configuration/userSettings/setting[@name='phoneNumber']");
phoneNumberNode.FirstChild.InnerText = this._cloudPublisherWebURL;
现在,在更新期间我想更新phoneNumber和地址。地址可能在配置文件中,也可能不是。
如果SelectSingleNode为null,我想创建一个具有给定路径的节点并设置其值。
XmlNode addressNode = theConfig.SelectSingleNode("configuration/userSettings/setting[@name='address']");
if(addressNode == null)
{
//..Create the node here
}
如何在给定路径上创建具有值的节点?
答案 0 :(得分:0)
XmlNode addressNode = theConfig.SelectSingleNode("configuration/userSettings");
XmlNode setting = addressNode.Item(0).SelectSingleNode("configuration/userSettings/setting[@name='phoneNumber']");
setting.SetAttribute("name", "address"); //this is to change the name attribute value into address
