I am simple call this con1 function in c #, but each time the values are the same, should excuse me everybody how to modify

CodePudding user response:

You should put it into a c # DLLS are available, and then to call

The DLL has can use, I just make a list including the realization of the function, there is no question of a single read value, multiple calls to read value is always the same number

CodePudding user response:

Is any update of the parameter value, the problem has been solved!!!!!!

CodePudding user response:

The inside of the DLL value you can't update, equivalent to every time is to call, c # local try the value to exist
