这个代码不是原著，是从博客园找的，具体链接找不到了，再次记录一下，以备后面使用，
2、c#调用jar包
通过官网下载ikvm-0.42.0.3.zip、ikvmbin-0.42.0.3.zip、openjdk6-b16-stripped.zip这三个文件，解压ikvm-0.42.0.3.zip，进入bin目录，直接运行ikvmc -out:IKVM.dll test.jar 其中IKVM.dll为生成dll的名称，test.jar为你要转成dll的jar包，转完之后直接通过程序引用
引用完毕后引入名称空间就可以调用里面的类了
3、服务器设置bios里面的电源选项
在此在说明一下，以上信息仅用作以后查阅使用，均不是原著。
