关于配置节的问题

[jjstar]

下面是帮助文件中的例子，我什么运行出错呢？怎么改呀？

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

<sampleSection setting1="Value1" setting2="value two"
setting3="third value" />
///////////////////
using System;
using System.Collections;
using System.Configuration;

class MyConfigurationReader {

public void ReadMySettings() {
IDictionary sampleTable = (IDictionary)
ConfigurationSettings.GetConfig("sampleSection");
string value1 = (string)sampleTable["setting1"];
string value2 = (string)sampleTable["setting2"];
string value3 = (string)sampleTable["setting3"];
}
}

我写了一个class，
实现了IConfigurationSectionHandler，
就OK了，
为什么系统内置的就不好用呢？
:(

你的代码有两处错误:
1.配置节中type的
指定从配置文件中读取节的配置节处理程序类的名称，也就是说
MyConfigurationReader类 必须改成SingleTagSectionHandler而且命名空间必须是System.Configuration。
2.SingleTagSectionHandler必须实现IConfigurationSectionHandler接口。

[jjstar]

SingleTagSectionHandler是系统内置的，当然实现了IConfigurationSectionHandler接口

[jjstar]

自己搞定了，
using System;
using System.Collections;
using System.Configuration;
using System.Xml;
using System.Collections.Specialized;
namespace ServiceSales.ClassLib
{
/// <summary>
/// CConfig 的摘要说明。
/// </summary>
public class CConfig : IConfigurationSectionHandler
{
public Object Create(Object parent, object configContext, XmlNode section)
{
NameValueCollection settings;
try
{
NameValueSectionHandler baseHandler = new NameValueSectionHandler();
settings = (NameValueCollection)baseHandler.Create(parent, configContext, section);
}
catch
{
settings = null;
}
return settings;
}
}
}
