Binary Access Read Write Lock Read Write in vb.net?

[green.pitch]

Hello,
I am looking for Binary File read Write Lock access in vb.net.

In VB6 we can lock any file with the following code:

Open filename For Binary Access Read Write Lock Read Write As #1

How to do same work with vb.net?


Thanks !

The FileStream class allows you to read and write binary data from and to a file. Here's a link to the documentation for the class constructors, which provide all you need to specify how the file should be accessible:

You can also call the File.Open method to create a FileStream, which may be slightly simpler options-wise:

I cannot recommend strongly enough that you do not use that old VB6-style I/O in VB.NET. We're using VB.NET now so let's use it.

FileOpen(1, "TESTFILE", OpenMode.Binary, OpenAccess.Read, _
   OpenShare.LockRead)

WILCO, or in a more common language "I will Do as you told me!"

Ehh....I would strongly recommend following jmc's advice and don't use that. That wouldn't play nice with other file handling operations in the Framework since they all use FileStreams in one way or another. FileOpen is nothing more than a carrot meant to lure VB6 developers into VB.Net.

(I realize this is a very old thread)
A carrot? Why do many .net users have to pee on everything VB6? I hate file streams unless I'm writing files as streams. And, the VB6 method more-closely mirrors what the OS has always provided.
Faster, leaner, and doesn't require a massive .net runtime package. .net is cool and all, but don't beat up the tools that .net was built from!
