c# - Got hit by an OverflowException -

-

in method below on last line i'm getting exception:

system.overflowexception: value either large or small int32.

i can't explain why because i'm checking explicitly that:

private int32 convertvalue(double value) {    if (value > int32.maxvalue)    {       console.writeline("couldn't convert value " + value + " int32");       return int32.maxvalue;    }    else if (value < int32.minvalue)    {       console.writeline("couldn't convert value " + value + " int32");       return int32.minvalue;    }    else    {       return convert.toint32(value);    } }

also check double.isnan(value).

compares nan yield false.

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...
