foreach and public GetEnumerator method

Tamer Ibrahim

Hi,

foreach is not able to iterate through the collection because there is no
public GetEnumerator method

the foreach is not working in this code snippet, How can I resolve this ?

bool ValidatingReser vation()

{

ValidReservatio n.Fill(dtValidR eservation, DropDownListFil eID.SelectedVal ue);

int i = 0; bool boolResult = false;

DateTime r1start = Convert.ToDateT ime(BasicDatePi ckerFromDate.Se lectedDate),

r2start = Convert.ToDateT ime(dtValidRese rvation.Rows[i]["StartDdate "]),

r1end = Convert.ToDateT ime(BasicDatePi ckerToDate.Sele ctedDate),

r2end = Convert.ToDateT ime(dtValidRese rvation.Rows[i]["EndDdate"]) ;
if (dtValidReserva tion.Rows.Count == 0) return true;

else foreach( int i in dtValidReservat ion.Rows[i])

{

boolResult = (r1start == r2start) || (r1start r2start ? r1start <= r2end :
r2start <= r1end);

if(boolResult) break;

}

return boolResult;

}

Hi again,
I rewrite my code and It is working now. But I need to enhance it more of
possible ...
Thanks in advance.

bool boolResult = false; int i=0;

if (dtValidReserva tion.Rows.Count == 0) return false;

else foreach( DataRow row in dtValidReservat ion.Rows)

{

boolResult = (Convert.ToDate Time(BasicDateP ickerFromDate.S electedDate) ==
Convert.ToDateT ime(dtValidRese rvation.Rows[i]["StartDate"])) ||
(Convert.ToDate Time(BasicDateP ickerFromDate.S electedDate) >
Convert.ToDateT ime(dtValidRese rvation.Rows[i]["StartDate"]) ?
Convert.ToDateT ime(BasicDatePi ckerFromDate.Se lectedDate) <=
Convert.ToDateT ime(dtValidRese rvation.Rows[i]["EndDate"]) :
Convert.ToDateT ime(dtValidRese rvation.Rows[i]["StartDate"]) <=
Convert.ToDateT ime(BasicDatePi ckerToDate.Sele ctedDate));

i++;

if (boolResult) { Msg.Text += "overlap"; break; }

}

return boolResult;

simplify and display ur code in a more brief way, almost pseudo-codel
like, so what it is not considered a homework

for vs foreach for array enumeration

I'm a bit confused about the differences of these two commands (what is the right word for commands here?) when used to enumerate the contents of an array. The below example uses both foreach and for to enumerate the contents of the array. Also as well as explaining the differences could you explain why the foreach messagebox isn't working below. Many TIA.

RE: foreach pretty useless for composite classes, don't ya thunk?

by: =?Utf-8?B?RmFtaWx5IFRyZWUgTWlrZQ==?= | last post by:

An example of a slightly more complicated class might be to have a collection of first names, and a collection of last names in your class. The IEnumerable functions then could return the complete set of all possible combinations of first and last name.

by: Peter Morris | last post by:

I am not sure what you are asking. You seem to be asking how to implement a plain IEnumerable on a composite structure, but then your example shows a flat structure using "yield". Your subject makes me infer that you think foreach is enirely useless for composite structures. I will address the subject text, because that makes the most sense to me :-) Take the following class public class MyTreeNode : IEnumerable<MyTreeNode> {

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
