Lzip is better than gzip and bzip2 from a data Decompression speed is intermediateīetween gzip and bzip2. Lzip can compress about as fast as gzip (lzip -0) or compress mostįiles more than bzip2 (lzip -9).

Lzip is a lossless data compressor with a user interface similar A cyclic redundancy check (CRC) is performed as one of the last operations of this method.Lzip - reduces the size of files SYNOPSIS If data is found in an invalid format, an InvalidDataException is thrown as one of the last operations.

Public static class MemoryWriteReadExample ![]() The following example shows how to compress and decompress bytes by using the Read and Write methods. Use BinaryReader for reading primitive data types. The method is free to return fewer bytes than requested even if the end of the stream has not been reached. Read returns 0 only when there is no more data in the stream and no more is expected (such as a closed socket or end of file). This method will block until at least one byte of data can be read, in the event that no data is available. The current position within the GZip stream is advanced by the number of bytes read however, if an exception occurs, the current position within the GZip stream remains unchanged. This method read a maximum of buffer.Length bytes from the current stream and store them in buffer. Use the ReadAsync method to read asynchronously from the current stream. Use the CanRead property to determine whether the current instance supports reading. This can be less than the number of bytes allocated in the buffer if that many bytes are not currently available, or zero (0) if the end of the stream has been reached. The total number of bytes read into the buffer. ![]()
