我写了一个程序，想在c#中读取Web.config文件中的字段，怎么读不出来，高手指点一下呀！
主程序是：
using System;
using System.Collections.Specialized;
using System.Configuration;

namespace test2
{
class test2
{
static void Main(string[] args)
{
string m_connString;
bool m_usePlainTextDbCxnString;
ConfigurationSettings.GetConfig ("Web.config");
m_usePlainTextDbCxnString = Convert.ToBoolean(ConfigurationSettings.AppSettings["sqlConn.UsePlainText"]);

if (m_usePlainTextDbCxnString)
{
m_connString = ConfigurationSettings.AppSettings["sqlConn.ConnectionString.PlainText"];
Console.WriteLine (m_connString);
Console.WriteLine ("one Ok ");
}
else
{
string cxnStringCipherText = ConfigurationSettings.AppSettings["sqlConn.ConnectionString.Protected"];
Console.WriteLine(cxnStringCipherText);
Console.WriteLine("two Ok");
}
}
}


}

Web.config文件是：
<configuration>
<appSettings>
<add key="sqlConn.ConnectionString.PlainText" value="workstation id='01';packet size=4096;user id=IVUser;integrated security=SSPI;data source='01';persist security info=False;initial catalog=IssueVision" />
<add key="sqlConn.ConnectionString.Protected" value="workstation id='01';packet size=4096;user id=IVUser;integrated security=SSPI;data source='01';persist security info=False;initial catalog=IssueVision" />
<add key="sqlConn.UsePlainText" value="false" />
</appSettings>
</configuration>

ConfigurationSettings.GetConfig ("Web.config");

方法的返回值保存到哪里去了???

我对读取web.config文件不是太明白，那位高手能给我解释一下么？我看了些这方面的书，但这个都讲得很模糊，不是很懂，因为是自学，所以进展比较缓慢。
上段代码是根据issuevision上的代码改编的，其实不太明白原理，很希望高手讲得通俗些。呵呵。

简单的写写,就是一个按纽触发
if(this.openFileDialog1.ShowDialog()==DialogResult.Cancel)
return;
string FileName=this.openFileDialog1.FileName;
if(FileName.Length<1)
return;
System.Xml.XmlTextReader MyReader=new System.Xml.XmlTextReader(FileName);
//从XmlTextReader中读取数据
this.dataSet1.ReadXml(MyReader,XmlReadMode.ReadSchema);
this.dataGrid1.DataSource=this.dataSet1;
this.richTextBox1.Visible=false;
this.dataGrid1.Visible=true;

注意如果dataset1自己设置了命名,一定要和xml对应

直接用System.Configuration.ConfigurationSettings.AppSetting["sqlConn.ConnectionString.PlainText"];
