DeflateStream.Write Method (Byte[], Int32, Int32)
.NET Framework (current version)
Writes compressed bytes to the underlying stream from the specified byte array.
Assembly: System (in System.dll)
Parameters
- array
-
Type:
System.Byte[]
The buffer that contains the data to compress.
- offset
-
Type:
System.Int32
The byte offset in array from which the bytes will be read.
- count
-
Type:
System.Int32
The maximum number of bytes to write.
The following example shows how to compress and decompress bytes by using the Read and Write methods.
using System; using System.Text; using System.IO; using System.IO.Compression; namespace ExampleConsoleApplication { class Program { static void Main(string[] args) { UnicodeEncoding uniEncode = new UnicodeEncoding(); byte[] bytesToCompress = uniEncode.GetBytes("example text to compress and decompress"); Console.WriteLine("starting with: " + uniEncode.GetString(bytesToCompress)); using (FileStream fileToCompress = File.Create("examplefile.gz")) { using (DeflateStream compressionStream = new DeflateStream(fileToCompress, CompressionMode.Compress)) { compressionStream.Write(bytesToCompress, 0, bytesToCompress.Length); } } byte[] decompressedBytes = new byte[bytesToCompress.Length]; using (FileStream fileToDecompress = File.Open("examplefile.gz", FileMode.Open)) { using (DeflateStream decompressionStream = new DeflateStream(fileToDecompress, CompressionMode.Decompress)) { decompressionStream.Read(decompressedBytes, 0, bytesToCompress.Length); } } Console.WriteLine("ending with: " + uniEncode.GetString(decompressedBytes)); } } }
