Demonstrate Binary Data Encoding Methods

Demonstrates binary data encoding methods.

Note: This example requires Chilkat v9.5.0.64 or later.

C#

Chilkat.BinData binData = new Chilkat.BinData();

//  Append 10 bytes: 00, 01, 02, 03, 04, 05, 06, 07, 08, 09
binData.AppendEncoded("00010203040506070809","hex");

//  Show that binData contains 10 bytes.
Debug.WriteLine("num bytes = " + Convert.ToString(binData.NumBytes));

//  Get as base64
Debug.WriteLine("base64: " + binData.GetEncoded("base64"));

//  Get a chunk of the binary data.
//  The 1st byte is at index 0.
//  The output should be "02030405"
int offset = 2;
int numBytes = 4;
Debug.WriteLine("chunk: " + binData.GetEncodedChunk(offset,numBytes,"hex"));

//  Copy the bytes to a StringBuilder using the base64url encoding
Chilkat.StringBuilder sb = new Chilkat.StringBuilder();
binData.GetEncodedSb("base64url",sb);
Debug.WriteLine("base64url: " + sb.GetAsString());

//  Remove a chunk from the binary data
offset = 2;
numBytes = 4;
binData.RemoveChunk(offset,numBytes);
//  The bytes remaining are 00,01,06,07,08,and 09
Debug.WriteLine("after removing chunk: " + binData.GetEncoded("hex"));
