[求助]关于获取web.config文件自定义节点值

[hnsprite]

部分配置文件如下：
<?xml version="1.0"?>

<configuration>

<configSections>

<section name="SpringOverrideProperty" type="System.Configuration.SingleTagSectionHandler"/>

</configSections>

<SpringOverrideProperty>

<add key="DbProvider.ConnectionString" value="Persist Security Info=False;User ID=sa;Initial Catalog=SFY;Data Source=172.16.73.69"/>

<add key="XX" value="XXX"/>

</SpringOverrideProperty>

</configuration>
我想读取key为DbProvider.ConnectionString的value
这个要怎么做？
谢谢

高手在哪里？

为什么不把链接字符串放到
<connectionStrings/> 这个里面。

[jojoqiong]

<add name="DbProvider.ConnectionString" connectionString="Persist Security Info=False;User ID=sa;Initial Catalog=SFY;Data Source=172.16.73.69"/>
</connectionStrings>

[jojoqiong]

读取方式：System.Configuration.ConfigurationManager.ConnectionStrings["DbProvider.ConnectionString"];

不是我不想啊，公司一定要用那破FastSpring.net 没有办法啊
我要增加现有项目一些功能，又不能改变原来的玩意儿

//web.config 里的连接方法1：
 
<connectionStrings>
<add name="sqlConn" connectionString="Server=(local);DataBase=SmartWeb;User ID=sa;Password=" providerName="System.Data.SqlClient"/>
</connectionStrings>
//读取方法：
using System.Data.SqlClient; //引入此命名空间
using System.Collections;
string strConn = ConfigurationManager.ConnectionStrings["sqlConn"].ToString();
SqlConnection conn = new SqlConnection(strConn);
//----------------------------------------------------------------------------------------------------------
//web.config 里的连接方法2：
<appSettings>
<add key="sqlConn" value="server=(local);database=smartweb;uid=sa;pwd="/>
</appSettings>
//读取方法：
using System.Data.SqlClient; //引入此命名空间
using System.Collections;
string strConn = System.Web.Configuration.WebConfigurationManager.AppSettings["sqlConn"].ToString();
SqlConnection conn = new SqlConnection(strConn);
 
//====================================================================
//ACCESS连接方法：
<appSettings>
   <add key="accessConn" value="provider=microsoft.jet.oledb.4.0;data source="/>
   <add key="dbPath" value="~/App_Data/SmartWeb.mdb"/>
</appSettings>
//读取方法：
using System.Data.OleDb; //引入此命名空间
 
string strconn = System.Configuration.ConfigurationManager.AppSettings["accessConn"].ToString()
        + System.Web.HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings["dbPath"]) + ";";
        OleDbConnection conn = new OleDbConnection(strconn);
        try
        {
            conn.Open();
            Response.Write("连接成功");
            conn.Close();
        }
        catch (Exception ex)
        {
            Response.Write("数据库连接失败:错误信息: <br/>" + ex.ToString());
        }

楼上的回答是正确的，我这个列子更全面，试试

[hnsprite]

楼上的都不行啊，没有办法
只能用我想到的办法啦~~~~

XmlDocument DocXml = new XmlDocument();
DocXml.Load(Server.MapPath("web.config"));
XmlNode xmlNo = DocXml.SelectSingleNode("//SpringOverrideProperty/add[@key=\"DbProvider.ConnectionString\"]");
Num1.Text = xmlNo.Attributes["value"].Value.ToString();

你是否定义了ConfigurationSection的映射类，类似下面的：

public class Location : ConfigurationElement
{
[ConfigurationProperty("computer",
IsRequired = true)]
public string Computer
{
get { return (string)base["computer"]; }
set { base["computer"] = value; }
}
[ConfigurationProperty("port",
IsRequired = true)]
public int Port
{
get { return (int)base["port"]; }
set { base["port"] = value; }
}
[ConfigurationProperty("location",
IsRequired = true)]
public Location Location
{
get { return (Location)base["location"]; }
set { base["location"] = value; }
}
[ConfigurationProperty("endpoint",
IsRequired = true)]
public string Endpoint
{
get { return (string)base["endpoint"]; }
set { base["endpoint"] = value; }
}
}
