title: How to convert char array into int?
body: <p>I am taking input from a text box. I've saved the input digits from text box to an array like this:</p>
  
  <pre><code>char[] _array = textBox1.Text.ToCharArray(0, textBox1.Text.Length);
  </code></pre>
  
  <p>Now I want to convert the array to an int array because I want to perform mathematical operations on each index of the array.</p>
  
  <p>How can I achieve the goal?
  Thanks.</p>
