New code Lines in c# project is not executed
<p>I`m a new guy to c# and I try to add a some code to a certain class in my c# project in order to remove some characters from a string. These lines of codes are <strong>not executed</strong> at run time and the debugger steps over it.So,</p>

<p><strong>1)</strong> How to make the new lines added to an existing project execute? </p>

<p><strong>2)</strong> Is there a property in Visual studio 2005 that prevents developers from changing existing code?</p>

<p><strong>3)</strong> Is it some Property related to the c# project that specifies a privilege of code change?</p>
