title: Call variable with string c# console application
body: <p>Is there a way so that if you have a string containing the name of a defined variable, you can call that variable. For example:</p>
  
  <pre><code>string Hello = "Hello";
  Console.WriteLine("What is the name if the variable?");
  userInput = Console.ReadLine();
  userInput.Replace('Hello', 'Hi'); &lt;---//This would replace the value of Hello not the value of userInput
  </code></pre>
  
  <p>How would I Let the user input the variable name then use the string to call that variable?</p>
