C# to Lambda - count decimal places / first significant decimal -

-

out of curiosity, there equivalent lambda expression following?

... started using lambda not familiar yet methods zip ...

//pass in double , return number of decimal places //ie. 0.00009 should result in 5  //edit: number of decimal places good. //however, want position of first non-zero digit  //after decimal place.  int count=0; while ((int)double_in % 10 ==0) { double_in*=10; count++; } 

 double1.tostring().skipwhile(c => c!='.').skip(1).count()

for example:

double double1 = 1.06696; int count = double1.tostring().skipwhile(c => c!='.').skip(1).count(); // count = 5;  double double2 = 16696; int count2 = double2.tostring().skipwhile(c => c!='.').skip(1).count(); // count = 0;

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...
