这是个简单的实现ARMA3连接Reids缓存服务器的源代码，使用C#实现
自行编译为dll，放置服务的目录下即可。
食用方法:
//在服务端初始化后首先连接redis服务器，只需要连接一次不能重复执行如要重复请修改源代码。
//参数: [ip,端口,密码]，redis有密码:
"ArmaMapsExt_x64" callExtension ["connectRedis",["127.0.0.1","6379","123456"]]
//redis无密码:
"ArmaMapsExt_x64" callExtension ["connectRedis",["127.0.0.1","6379"]]
//储存一个字符串至redis缓存服务器，参数:[key,value]
//缓存无限期:
"ArmaMapsExt" callExtension ["sendMsg",["usename","小明"]]
//缓存有限期(单位:秒):
"ArmaMapsExt" callExtension ["sendMsg",["usename","小明","60"]]
//从key中获取一个缓存字符串，参数:[key]
_data = "ArmaMapsExt" callExtension ["getMsg",["username"]]
//如果命中缓存则返回值，否则返回空字符串
注意:全程只能在服务器上执行! 模组也只能服务器挂载
如果你要在客户端测试，必须关闭be，否则会被阻止!
