Stack around the variable ' data ' was corrupted.

C # interacts with C + +

• C + + pushes the struct to C #, which is received in the ref struct format.
  The above error has been found for several days. Although it is clear that memory is out of bounds, it is only today that the problem is suddenly thought of.
  The original is the C + + layer of # define XXX = ' n ' replaced by the C # layer of enum ... xxx = (byte) ' n '

• The enum of C # is by default int, and naturally does not match with Char, so the above error occurs.
