UWP - search the gridview regardless of uppercase or lowercase letters

I have a gridview containing files from within a folder and adding a search function. I encountered a problem while searching, that is if the file name contained a large letter, but I typed it using lowercase letters, then it can't be found. Like the picture below:

  1. use lowercase image 1

  2. Use uppercase image 2

How to overcome it, so as not to care about lowercase letters and uppercase letters in search results?

Code:

ObservableCollection<Book> datasource = new ObservableCollection<Book>();
private void SearchText_TextChanged(object sender, TextChangedEventArgs e)
            {
                if (!string.IsNullOrWhiteSpace(searchText.Text))
                {
                    this.itemGridView.ItemsSource = this.datasource.Where((item) => { return item.Name.Contains(searchText.Text); });
                }
                else
                {
                    this.itemGridView.ItemsSource = datasource;
                }
            }

Book.cs:

public class Book
    {
        public string Name { get; set; }

        public string Direktori { get; set; }

        public ImageSource Image { get; set; }
    }

Add a StringComparison parameter to the Contains() method. So like this:

return item.Name.Contains(searchText.Text, StringComparison.OrdinalIgnoreCase);
