While writing my last post, I was looking at the code to see if it was really something I wanted to post for general scrutiny and saw that I could use Linq to do the same thing. Here’s the old code:<\/p>\n

\n
\n
bool<\/span> visible = false<\/span>;<\/pre>\n
foreach<\/span> (var screen in<\/span> Screen.AllScreens)<\/pre>\n
{<\/pre>\n
    if<\/span> (screen.WorkingArea.Contains(this<\/span>.DesktopLocation))<\/pre>\n
    {<\/pre>\n
        visible = true<\/span>;<\/pre>\n
        break<\/span>;<\/pre>\n
    }<\/pre>\n
}<\/pre>\n
if<\/span> (!visible)<\/pre>\n
    this<\/span>.Location = new<\/span> Point(100, 100);<\/pre>\n<\/div>\n<\/div>\n
I changed it to (query syntax):<\/p>\n
\n
\n
var visible = (from screen in<\/span> Screen.AllScreens<\/pre>\n
               where<\/span> screen.WorkingArea.Contains(this<\/span>.DesktopBounds)<\/pre>\n
               select screen).Count() > 0;<\/pre>\n
if<\/span> (!visible)<\/pre>\n
    this<\/span>.Location = new<\/span> Point(100, 100);<\/pre>\n<\/div>\n<\/div>\n
Or the extension method code:<\/p>\n
\n
\n
var visible = Screen.AllScreens.Any(screen => <\/pre>\n
    screen.WorkingArea.Contains(DesktopBounds));<\/pre>\n
if<\/span> (!visible)<\/pre>\n
    this<\/span>.Location = new<\/span> Point(100, 100);<\/pre>\n<\/div>\n<\/div>\n
A quick run down of the conversion to the query syntax version:<\/p>\n
