See more JSON Examples

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");
