Semantic Text Query In Windows 10

Here are the steps:

Step 1: Open a blank app and add two TextBlocks and a button either from the toolbox or by copying the following XAML code into your grid.

<StackPanel Margin="10,40,0,0">
<TextBlock Text="Type the word to find" ></TextBlock>
<TextBox Name="textToFind" Width="200" Margin="0,10,0,0" HorizontalAlignment="Left"></TextBox>
<TextBlock Text="Type or Copy and Paste a sentence to find from " Margin="0,10,0,0" ></TextBlock>
<TextBox Name="sentence" Height="100" Width="300" HorizontalAlignment="Left" Margin="0,10,0,0" TextWrapping="Wrap"></TextBox>
<Button Name="find" Content="Find" Height="40" Width="120" Click="find_Click" Margin="0,10,0,0" ></Button>
<TextBlock Name="result" TextWrapping="Wrap" Width="300" HorizontalAlignment="Left"></TextBlock>
</StackPanel>

Step 2: Add the following namespaces to your project which is needed in further C# code.

using System.Collections.Generic;
using Windows.Data.Text;
using Windows.UI.Text;
using Windows.UI.Xaml.Documents;

Step 3: Copy and paste the following code to the cs page which will be called on button click event and the corresponding text will be highlighted.

private void find_Click(object sender, RoutedEventArgs e)
{
result.Text = "";
var mySemanticTextQuery = new Windows.Data.Text.SemanticTextQuery(textToFind.Text);
IReadOnlyList<Windows.Data.Text.TextSegment> ranges = mySemanticTextQuery.Find(sentence.Text);
HighlightRanges(result, sentence.Text, ranges);
}
public void HighlightRanges(TextBlock tb, String TextContent, IReadOnlyList<TextSegment> ranges)
{
int currentPosition = 0;
foreach (var range in ranges)
{
if (range.StartPosition > currentPosition)
{
int length = (int)range.StartPosition - currentPosition;
var subString = TextContent.Substring(currentPosition, length);
tb.Inlines.Add(new Run() { Text = subString });
currentPosition += length;
}
var boldString = TextContent.Substring((int)range.StartPosition, (int)range.Length);
tb.Inlines.Add(new Run() { Text = boldString, FontWeight = FontWeights.Bold });
currentPosition += (int)range.Length;
}
if (currentPosition < TextContent.Length)
{
var subString = TextContent.Substring(currentPosition);
tb.Inlines.Add(new Run() { Text = subString });
}
tb.Inlines.Add(new Run() { Text = "\r\n" });
}

Step 4: Run your application and test yourself.
