The C# equivalent
<p>I am trying to close the program :HHTCntrl.exe as if the user clicked exit on that program. I have the following Borland C++ code. What is the C# equivalent?</p>

<pre><code>FILE *sf;
AnsiString ClosePollControl = AnsiString("HHT")+cbHHTNo-&gt;Text+AnsiString(".cls");
sf = fopen(ClosePollControl.c_str(),"w");
fclose(sf);
</code></pre>
