服务器重装后网站后台出现错误
晕死。我也碰到这个现象了。码下
没办法解决，码下轻聊源码好像是码下与服务器上的权限有关。
开始以为是码下lpk.dll 源码dll key 的原因。我都把Castle.net for 2.0的码下heml5源码源码都重新编译了。还是码下出现这个问题。
解决方法：
给C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\DSS\MachineKeys文件夹Everyon用户加上"写"权限。码下这样就可以解决了。码下
但服务器管理员不允许加“写”权限，码下怕系统安全问题。码下我晕~~~~~~~~
c#读取Config文件的码下问题
应用程序配置文件（App.config）是标准的 XML 文件，XML 标记和属性是码下c 控件按钮源码区分大小写的。它是码下可以按需要更改的，开发人员可以使用配置文件来更改设置，码下winform餐饮系统源码而不必重编译应用程序。
对于一个config文件：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="ServerIP" value=".0.0.1"></add>
<add key="DataBase" value="WarehouseDB"></add>
<add key="user" value="sa"></add>
<add key="password" value="sa"></add>
</appSettings>
</configuration>
对config配置文件的读写类：
