Prevents other processes from reading from or writing to the FileStream.
Assembly: mscorlib (in mscorlib.dll)
abstract Lock : position:int64 * length:int64 -> unit override Lock : position:int64 * length:int64 -> unit
Locking a range of a file stream gives the threads of the locking process exclusive access to that range of the file stream.
For a list of common file and directory operations, see Common I/O Tasks.
The following code example demonstrates how to lock part of a file so another process cannot access that part of the file even though it has read/write access to the file. Run the program simultaneously in different command windows and investigate using the different console input options.
