c# - Calculate execution time of one or more lines of code -

-

is there way (a class-made in c #) that allow me to calculate the time required to execute some lines in program.

ex :

try {   string connectionstring = getconnectionstring();   using (sqlconnection conn = new sqlconnection(connectionstring))   {     conn.open();      ***// start counting:      // time = 0***       using (sqlcommand cmd = new sqlcommand(      “select * books”, conn))       using (sqldatareader reader = cmd.executereader())        {          while (reader.read())           {              console.writeline(“{0}\t{1}\t{2}”,               reader.getint32(0),              reader.getstring(1),               reader.getint32(2));           }     ***// end counting     // time = 10 sec***   } }

one option use built-in stopwatch class:

var sw = stopwatch.startnew();  //  sw.stop(); console.writeline("time elapsed: {0} milliseconds", sw.elapsedmilliseconds);

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

(the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
