Read all contents of memory mapped file or Memory Mapped View Accessor without knowing the size of it

Question

I need something similar to ReadToEnd or ReadAllBytes to read all of the contents of the MemoryMappedFile using the MappedViewAccessor if I don't know the size of it, how can I do it?

I have searched for it, I have seen this question, but it is not the thing I am looking for:

How can I quickly read bytes from a memory mapped file in .NET?

Edit:

There is a problem, the (int)stream.Length is not giving me the correct length, it rather gives the size of the internal buffer used! I need to refresh this question because it is very pressing.

Answer 1

Rather use the Stream:

public static Byte[] ReadMMFAllBytes(string fileName)
{
    using (var mmf = MemoryMappedFile.OpenExisting(fileName))
    {
        using (var stream = mmf.CreateViewStream())
        {
            using (BinaryReader binReader = new BinaryReader(stream))
            {
                return binReader.ReadBytes((int)stream.Length);
            }
        }
    }
}
