(C#) Compress String Feed to Base64This example receives incoming text data in chunks, compresses as a stream, and accumulates the compressed data in base64. The purpose is to demonstrate the BeginCompressStringENC, MoreCompressStringENC, and EndCompressStringENC methods.
// This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. bool success; Chilkat.StringBuilder sbCompressedBase64 = new Chilkat.StringBuilder(); Chilkat.Compression compress = new Chilkat.Compression(); compress.Algorithm = "deflate"; compress.Charset = "utf-8"; compress.EncodingMode = "base64"; Chilkat.StringBuilder sbIndex = new Chilkat.StringBuilder(); int i; for (i = 0; i <= 24; i++) { // Note: It is possible (and normal) for a BeginCompress* or MoreCompress* method to return // an empty string (or 0 bytes). When this happens, the input data is not lost. It will be flushed // in a subsequent call. sbIndex.Clear(); sbIndex.AppendInt(i); if (i == 0) { sbCompressedBase64.Append(compress.BeginCompressStringENC(sbIndex.GetAsString())); } else { sbCompressedBase64.Append(compress.MoreCompressStringENC(sbIndex.GetAsString())); } sbCompressedBase64.Append(compress.MoreCompressStringENC(": This is a line of data to be compressed...\r\n")); } // Flush any remaining output. sbCompressedBase64.Append(compress.EndCompressStringENC()); Debug.WriteLine("The base64 encoded compressed text:"); Debug.WriteLine(sbCompressedBase64.GetAsString()); // Now decompress in one call: string originalText = compress.DecompressStringENC(sbCompressedBase64.GetAsString()); Debug.WriteLine(originalText); |
