google vision OCR returning too much information

Question

I created a simple class to test out googles vision OCR API. I am passing in a simple image with 5 letters that should return a string with "CRAIG" in it. Although this API call returns a lot of extra information:

            "confidence": 0.99
        }
    ],
    "confidence": 0.98
}

How can I get only the letters returned instead?

class:

public static void Main(string[] args)
    {

        string credential_path = @"C:\Users\35385\nodal.json";
        System.Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", credential_path);

        // Instantiates a client
        var client = ImageAnnotatorClient.Create();
        // Load the image file into memory
        var image = Image.FromFile("vision.jpg");
        // Performs label detection on the image file
        var response = client.DetectDocumentText(image);

        foreach (var page in response.Pages)
        {
            foreach (var block in page.Blocks)
            {
                foreach (var paragraph in block.Paragraphs)
                {
                    Console.WriteLine(string.Join("\n", paragraph.Words));
                }
            }
        }


    }

The image I passed in was a simple word that I drew out in paint:

Answer 1

After some researching, the following provides me with the word and also a much cleaner output:

Block Text at (183, 105) - (674, 105) - (674, 253) - (183, 253)
  Paragraph at (183, 105) - (674, 105) - (674, 253) - (183, 253)
    Word: CRAIG

method:

foreach (var page in response.Pages)
            {
                foreach (var block in page.Blocks)
                {
                    string box = string.Join(" - ", block.BoundingBox.Vertices.Select(v => $"({v.X}, {v.Y})"));
                    Console.WriteLine($"Block {block.BlockType} at {box}");
                    foreach (var paragraph in block.Paragraphs)
                    {
                        box = string.Join(" - ", paragraph.BoundingBox.Vertices.Select(v => $"({v.X}, {v.Y})"));
                        Console.WriteLine($"  Paragraph at {box}");
                        foreach (var word in paragraph.Words)
                        {
                            Console.WriteLine($"    Word: {string.Join("", word.Symbols.Select(s => s.Text))}");
                        }
                    }
                }
            }
