How to divide a textblock into every single character to be able to analyze the characters one by one?

Question

Good morning, I would like some help on WPF / C # (Visual Studio): I have a TextBox where the user has to write a code that the program has to analyze. This code must be analyzed character for character because each character has a different meaning. How can I divide the text of the TextBox into every single character and then analyze it using the if? Thanks

Follow the steps,

1. Assuming you want to read the text entered in a text-box on a button click in code behind (I am not following MVVM or some other pattern for you as of now).

2. Add below code in your xaml

           <TextBox x:Name="MessageTextBox" />
           <Button Content="Home" Click="Button_Click"/>
   

3. Add below code in xaml.cs

   private void Button_Click(object sender, RoutedEventArgs e)
   {
    string textBoxValue = MessageTextBox.Text;
   
    if (string.IsNullOrWhiteSpace(textBoxValue))
    {
      // Display an error or warning message to ask user to enter some text.
       return;
    }
    else
    {
      foreach(char ch in textBoxValue)
      {
          // Now you have each character of the text entered in the textbox
          // You can write your logic now.
      }
    }
   }
   

Give a try using above statements and check it.
