using CcntCs;
Create Class Instance
In order to use CNT class library, create
a instance of class.
In the C# source code file (with .cs extension), add the following lines

How to Use Class Library Methods
When using
CNT driver functions in C#, call class library method other than calling
the function directly.
The functions of CNT driver are called by calling the methods of class
library.
All the
methods in the class library are defined with the name by omitting the
prefix [Cnt] of function name.
When using with C#, please use the method without prefix Cnt.
For example, when using CntInit function
Ret = cnt.Init ( ....
For example, when using CntReadCount function
Ret = cnt.ReadCount ( ....
