title: What does <T> denote in C#
body: <p>I'm new to C# and directly diving into modifying some code for a project I received. However, I keep seeing code like this : </p>
  
  <pre><code>class SampleCollection&lt;T&gt;
  </code></pre>
  
  <p>and I cannot make sense of what the </p>
  
  <pre><code>&lt;T&gt; 
  </code></pre>
  
  <p>means nor what it is called.</p>
  
  <p>If anyone would care to help me just name what this concept is called, I can search it online. However, I'm clueless as of now.</p>
