Passing a string variable as a ref between a c# dll and c++ dll
<p>I have a c# dll and a c++ dll . I need to pass a string variable as reference from c# to c++ . My c++ dll will fill the variable with data and I will be using it in C# how can I do this. I tried using ref. But my c# dll throwed exception . "Attempted to read or write protected memory. ... This is often an indication that other memory is corrupt". Any idea on how this can be done</p>
