as a simple example, i have a C function which receives an int,increment it and return incremented value.on the other side I enter the input number to textbox in C#.
how can i call C function to process the number and return it back from c#?Thanks in advance
You are looking for P/Invoke.
You do will need a Reference to
System.Runtime.InteropServices and then do the following, if your C DLL contains a function called
[DllImport("mylib.dll")] private static extern int increase_int(int in_value);
and use it from your code doing
int newValue = increase_int(oldValue);
