When using Visual C#.NET

Specification of Functions

In C#,a direct GPIB driver function is not called but the method of a class library is called.

The function of a GPIB driver is called from the method of a class library.

Since the method in a class library is defined by the form excluding prefix from the function from the first Please call according to it.

Ex.)In the case of a GpIni function

Ret = gpib.Ini ();
