Demonstrates how to extract a PDF file contained within JSON. The file is represented as a base64 string within the JSON. Note: This example can extract any type of file, not just a PDF file. C#

bool success = false;

Chilkat.JsonObject json = new Chilkat.JsonObject();

// Load the JSON.
success = json.LoadFile("qa_data/json/JSR5U.json");
if (success != true) {
    Debug.WriteLine(json.LastErrorText);
    return;
}

// The JSON we loaded contains this:

// 	{
// 	...
// 	...
// 	  "data": {
// 	    "content": "JVBERi0xLjQ..."
// 	  }
// 	...
// 	...
// 	}

Chilkat.StringBuilder sb = new Chilkat.StringBuilder();
json.StringOfSb("data.content",sb);

Chilkat.BinData bd = new Chilkat.BinData();
bd.AppendEncodedSb(sb,"base64");

success = bd.WriteFile("qa_output/a0015.pdf");
