SL015B读卡器通讯的DLL，目前厂家没提供了，和老型号的调用方法、参数等一默一样。-SL015B reader communication DLL, manufacturers do not currently provided, and the old model calls the method, parameters, like a mime.

其实是用C#写的，功能简单，读取id号码，但是实现了对外部dll的调用，适合参考开发，PS：以前做项目时，写的一个小demo(Actually written in C#, function to read the id number, but call external dll suitable reference development, PS: to do the project, write a small demo)
