Maybe I am missing something basic here, but I havent been able to figure it out.
I am writing out a map, which contains a custom type in the value, while the key is a string. I coudlnt use ReadMap/WriteMap so I had to use Random Access File's ReadObject/WriteObject.
This is my code:
I tried writing the whole map at once using WriteObject but I was getting the same errors so I tried breaking it down to string but still same issue.
Reading back:
The exception I get is:
I have used RAF with Lists/Custom types but this is the first time I needed to use them with maps. I must be doing something wrong but cant figure it out!
