Convert any File to Base64 (and back)

Demonstrates how to get the contents of any file as a base64 string, and then write it back. C#

bool success = false;

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

//  This example will load a PDF and return it as a base64 string.
success = bd.LoadFile("qa_data/pdf/helloWorld.pdf");
if (success != true) {
    Debug.WriteLine("Failed to load file.");
    return;
}

string b64Str = bd.GetEncoded("base64");
Debug.WriteLine(b64Str);

//  Now write the base64 string back to the binary PDF file:
Chilkat.BinData bd2 = new Chilkat.BinData();
success = bd2.AppendEncoded(b64Str,"base64");
success = bd2.WriteFile("qa_output/helloWorld.pdf");
