scrnsave.scr
1、通过“组策略”来进行修改
开始——运行——gpedit.msc——用户配置——管理模板——
控制面板——显示——隐藏“屏幕保护程序”选项卡——属性——选择“未配置”——确定。
2、通过“注册表”来进行修改
开始——运行——regedit——HKEY_CURRENT_USER\Control Panel\desktop
双击ScreenSaveActive,其键值为0或1,为“0”时表示禁用屏幕保护功能,为“1”则表示可用,
刷新后重启电脑。
3、查看Windows--system32里 有没有scrnsave.scr文件,没有就不能开启屏保,
到其它电脑里找到复制过来。

Reflector is a class browser for .NET components. It allows browsing and searching the meta data, IL instructions, resources and XML documentation stored in a .NET assembly. Reflector was first released in October 2000 running on .NET Framework 1.0 Beta. <br><br>LINQ and .NET Framework 3.5: Reflector supports query expressions and other concepts introduced in C# 3.5. To enable this feature select ".NET 3.5" under View, Options, Disassembler, Optimization. <br><br>.NET Framework compatibility: Reflector runs on all versions of the .NET Framework using its own assembly loading infrastructure which does not rely on the Reflection API. For example, Reflector can load .NET Framework 2.0 assemblies without having the .NET Framework 2.0 installed. <br><br>Assembly Lists: When launched for the first time, Reflector allows you to choose a default set of assemblies. The list of assemblies is then stored in the Reflector.cfg file and will be loaded next time you open the program. Reflector allows creating multiple assembly lists and switching between the lists using the File, Open List dialog. To choose a different set of default assemblies for the current assembly list you should remove all assemblies from the list (DEL) and invoke the Refresh command (F5). <br><br>Assembly Cache: When resolving an assembly reference, Reflector will first search the local path next to the assembly holding the reference and then falls back to the cache directories defined in the Reflector.cfg file. Reflector does not search the Global Assembly Cache (GAC) unless you add "%SystemRoot%\Assembly" to the cache directories list. <br><br>Assembly Versioning: By default, assembly version numbers are ignored when resolving type and member references. You can enable side-by-side versioning in the options dialog but it is suggested to avoid this if possible. <br><br>
