data1 = null;
in an attempt to get the garbage collector to clear it out of memory. I'm still receiving the heap space Memory error. I've increased the memory allocation in my .ini file as well. I'm at my wits end here because if I can't pull this off, all my work has been for nill. Below is the snippet of code as I've tried to implement to use garbage collection to resolve. I know this isn't an SSCCE, but can anyone weigh in on why the garbage collector isn't clearing the unneeded objects from memory? Possible solutions? I'd really appreciate any help I can get!
