MVC 4 Reading bytes from HttpPostedFileBase

I what to read the bytes of a docx file and I have this method:

public ActionResult Create(Model myModel, HttpPostedFileBase fileUpload)
        {

                        MemoryStream ms = new MemoryStream();
                        byte[] bin = new byte[100]; 
                        long rdlen = 0;              
                        long totlen = fileUpload.InputStream.Length;    
                        int len;

                        while (rdlen < totlen)
                        {
                            len = fileUpload.InputStream.Read(bin, 0, 100);
                            ms.Write(bin, 0, len);
                            rdlen += len;
                        }
}

the total length of the file is 11338 but it only reads until 11326 then it stuck in an infinite loop because when it reaches the 11326 this len = fileUpload.InputStream.Read(bin, 0, 100); will only return 0 as a value. The weird thing is that if I upload a txt file it work as it should.

Thanks

This works, im using it myself for images uploaded. 

public ActionResult Create(Model myModel, HttpPostedFileBase fileUpload)
{ 
    byte[] Data = null;

    using (var binaryReader = new BinaryReader(fileUpload.InputStream))
    {
        Data = binaryReader.ReadBytes(fileUpload.ContentLength);
    }
}

        byte[] myFile;
        using (var memoryStream = new MemoryStream())
        {
            httpPostedFileBase.InputStream.CopyTo(memoryStream);
            myFile = memoryStream.ToArray();// or use .GetBuffer() as suggested by Morten Anderson
        }
