根据key name的名称读取value-----读取使用ConfigurationManager.AppSettings读取容易没读取到根目录中的key
public string GetXml(string name)
{
XmlDocument doc = new XmlDocument();
doc.Load("app.config");
XmlElement element = doc.SelectSingleNode("//add[@key='" + name + "']") as XmlElement; return element.GetAttributeNode("value").Value;
}
根据key name名称修改value值
public void UpdateXml(string name, string value)
{
XmlDocument doc = new XmlDocument();
doc.Load("app.config");
XmlElement element = doc.SelectSingleNode("//add[@key='" + name + "']") as XmlElement;
if (element != null)
{
XmlAttribute a = element.GetAttributeNode("value");
if (a != null)
{
a.Value = value;// 按实际需要来写
doc.Save("app.config");
}
}
}
