title: Difference between c# using and Java import
body: <p>I know that in java that we use *(asterisk) to import all the contents in a package like </p>
  
  <pre><code>import java.lang.*;
  </code></pre>
  
  <p>Then why don't we use same *(asterisk) in C# to import all the contents is there any method like in java to import all the contents.
  What is the difference between </p>
  
  <pre><code>import java.awt.*;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>using System.windows.forms;
  </code></pre>
