读XML文件

Question

 XML文件格式如下
<appSettings>
    <add key="webservice_url" value="http://localhost:1885/Acmeway.Business.Webservices/Service.asmx" />
 <\appSettings>
怎么读出http://localhost:1885/Acmeway.Business.Webservices/Service.asmx信息

Answer 1

app.config有专门的类可以处理。ConfigruationManager

Answer 2

例:有程序a,b 
B要用A的配置文件,能用ConfigruationManager吗

Answer 3

string webservice_url = System.Configuration.ConfigurationSettings.AppSettings["webservice_url"];

Answer 4

例:有程序a,b 
B要用A的配置文件,能用ConfigruationManager吗

Answer 5

ConfigruationManager 好象只对 WEB.CONFIG文件有效，
lz可以有以下2中方式处理
1.AB程序公用一个WEB.CONFIG文件，如果有2种以上的连接字符串可以用
<appSettings> 
    <add key="webservice_url1" value="http://localhost:1885/Acmeway.Business.Webservices/Service.asmx" /> 
<add key="webservice_url2" value="http://localhost:1885/Acmeway.Business.Webservices/Service.asmx" /> 
<\appSettings> 
    用 System.Configuration.ConfigurationSettings.AppSettings["webservice_url1"];
       System.Configuration.ConfigurationSettings.AppSettings["webservice_url1"];
    读出
2.单独读xml文件，也就先用一个XML保存连接字符串信息，然后读该信息，该方法很多

Answer 6

ConfigurationManager.AppSettings["webservice_url"]

Answer 7

XmlDocument doc = new XmlDocument();
doc.Load(file);
XmlNode node = doc.SelectSingleNode("/appSettings/add");Console.WriteLine(node.Attributes["value"].Value);

Answer 8

ConfigurationManager.AppSettings["webservice_url"]

Answer 9

lovefootball :
XmlNode node = doc.SelectSingleNode("/appSettings/add"); 
node是NULL的
我的格式
<appSettings>
    <add key="webservice_url" value="http://localhost:1885/Acmeway.Business.Webservices/Service.asmx" />

自己解决
 XmlDocument doc = new XmlDocument();
            doc.Load(Application.StartupPath + @"\Acmeway.Business.Main.exe.config");
            XmlNodeList DocdNodeNameArr = doc.DocumentElement.ChildNodes;//文档节点名称数组
            foreach (XmlElement DocXmlElement in DocdNodeNameArr)
            {
                if (DocXmlElement.Name.ToLower() != "appsettings") continue;//找到名称为 appsettings 的节点                XmlNodeList KeyNameArr = DocXmlElement.ChildNodes;//子节点名称数组
                if (KeyNameArr.Count <= 0) continue;                string KeyName = "";
                string KeyValue = "";
                for (int i = 0; i < KeyNameArr.Count; i++)
                {
                    if (!(KeyNameArr[i] is XmlElement)) continue;                    XmlElement xmlElement = KeyNameArr[i] as XmlElement;
                    if (xmlElement.Attributes.Count <= 0) continue;                    KeyName = xmlElement.Attributes["key"].InnerXml;//键值
                    switch (KeyName)
                    {
                        case "webservice_url":
                            KeyValue = xmlElement.Attributes["value"].Value;
                            break;
                    }
                }
            }
