How can I check if this file name is created or not in c# : <p>I'm trying to create a method that checks if this file ( todayfile.txt)  is created if not I need it to create it. Here is what I thinking of :</p>

<pre><code>private void ReadWater()
    {
        try
        {
            StreamReader inputFile;

            // I want to check if there is a file named ( Todayfile.txt )

            if (// if this file ( Todayfile.txt) is founded)
            {
                // Do this
            }

            else // if there is no file in this nmae ( Todayfile.text )
            {
                // create a new file 
            }

        }
        catch (Exception ex)
        {

        }

    }
</code></pre>
