这样写没有输出,错在哪里??
web.config 片段
<connectionStrings>
<add name= "ConnectionString " connectionString= "Data Source=250;Persist Security Info=True;User ID=chenyi;Password=123456;Unicode=True "
providerName= "System.Data.OracleClient " />
</connectionStrings>
PublicOracleCon.cs
public class PublicOracleCon
{
public readonly String OracleConnectionString = ConfigurationManager.AppSettings[ "ConnectionString "];
public PublicOracleCon()
{
}
public void printStr()
{
System.Console.WriteLine(OracleConnectionString);
}
}
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "Default.aspx.cs " Inherits= "_Default " %>

没有输出,错在哪里??
[解决办法]
public void printStr()
{
System.Console.WriteLine(OracleConnectionString); ／／这个是控制台输出呢，
／／web页面应该是Ｒesponse.write（OracleConnectionString）；
}
[解决办法]
楼主，你怎么还在用ASP的思维写代码？
PublicOracleCon poc = new PublicOracleCon();
poc.printStr();
放到
default.aspx.cs的Page_Load事件中
