How to initialize this dictionary
<p>I want to initialize a <code>string,datetime</code> dictionary, I want a "real" time value for each string. Later I want to insert the strings into drop down list as keys and the datetime as values.</p>

<pre><code>1 hour (string)- datetime(1 hour value)  
5 hour (string)- datetime(5 hour value)  
2 days (string)- datetime(2 days value)  
3 weeks (string)-datetime(3 weeks value) 
</code></pre>

<p>How do I make this kind of dictionary?</p>

<pre><code>public Dictionary&lt;string,DateTime&gt; TimeStep()
    {
        Dictionary&lt;string,DateTime&gt; timestep = 
        { "1  Hour", "2  Hours", "5  Hours", "10 Hours", "15 Hours", "24 Hours", "Two Days", "Five Days", "Ten Days", "Two Weeks", "Month" };
        return timestep ;        
    }
</code></pre>
