FileStream.CopyTo的代码示例8 - Seek()

    using System.IO;

        public override long Seek(long offset, SeekOrigin origin)
        {
            var position =
                origin == SeekOrigin.Begin ? offset :
                origin == SeekOrigin.Current ? _stream.Position + offset :
                _stream.Position - offset;

            // when offset pass limit first time, change current _stream from MemoryStrem to FileStream with TempFilename()
            if (position > _maxMemoryUsage && this.InMemory)
            {
                // create new filename if not passed on ctor (must be unique
                _filename = _filename ?? Path.Combine(Path.GetTempPath(), "litedb_" + Guid.NewGuid() + ".db");

                var file = new FileStream(_filename, FileMode.CreateNew, FileAccess.ReadWrite, FileShare.None, PAGE_SIZE, FileOptions.RandomAccess);

                // copy data from memory to disk
                _stream.Position = 0;
                _stream.CopyTo(file);

                // dispose MemoryStream
                _stream.Dispose();

                // and replace with FileStream
                _stream = file;
            }

            return _stream.Seek(offset, origin);
        }
