Example

The following code example enumerates through the text of an OCR result and writes to a string, preserving line breaks. It then writes the string to a TextBlock named tbResults.

private void OCR_OcrCompleted(object sender, OcrCompletedEventArgs e)
{
    // Make sure there is text.
    if (e.Result.Lines.Count == 0)
    {
        tbResults.Text = "No text found.";
        return;
    }

    // Read the text and print it to tbResults.
    string s = "";
    foreach (
            Line l in e.Result.Lines)
    {
        foreach (Word w in 
            l.Words)
        {
            s += w.Value + " ";
        }
        s += "\n";
    }
    tbResults.Text = s;
}
