hi ankit,\

You can use GZipStream class.

```
string fileToBeCompressed =//path of original file;string zipFilename = //path of zipped file; using (FileStream target = new FileStream(zipFilename, FileMode.Create,FileAccess.Write))using (GZipStream alg = new GZipStream(target, CompressionMode.Compress)){    byte[] data = File.ReadAllBytes(fileToBeCompressed);    alg.Write(data, 0, data.Length);    alg.Flush();}
```
