<p>I am checking the uploaded image in a registration form , where i need to use try catch blocks. here is my code:</p>

<pre><code>public bool CheckFileType(string FileName)
{
        string Ext = Path.GetExtension(FileName);
        switch (Ext.ToLower())
        {
            case ".gif":                   
                return true;
                break;
            case ".JPEG":                    
                return true;
                break;
            case ".jpg":                  
                return true;
                break;
            case ".png":                   
                return true;
                break;
            case ".bmp":                   
                return true;
                break;
            default:
