You can do this very easily using LINQ and TimeSpan.
First, get the minimum DateTime from the array(Min()).
Then get the maxumim DateTime from the array (Max()).
Using TimeSpan get the difference.

Something like

If you want to find the earliest or latest Date:
DateTime earliest = arr.Min(record => record.Date);
DateTime latest = arr.Max(record => record.Date);

Try this:
List<TimeSpan> dateIntervals = endDates.Select((eDate, ndx) => eDate - startDates[ndx]).ToList(); The Linq 'Select function overload that supplies an index is available as of .NET FrameWork 3.5.

Try this:
for (int i = start.Length - 2; i > -1; --i)
{
if (start[i+1] >= start[i] && start[i+1] <= end[i])
{
start[i + 1] = end[i];
}
}
for (int i = 0; i < start.Length; ++i)
{
timespan = end[i] - start[i];
timeDifference += timespan.Days;
}

yes but it is not remove overlap for the next time i mean for this one it is good |-----------|

but here |--------1-----|

how can make the telerik radTreeListView only allow selection of items under the same rootItem/ParentItem?
UK
-london
-london 1
-london --
-london 100
-Newcastle
-Newcastle 1
-Newcastle 2
-Newcastle 3
-liverpool
USA
-New york
-califonia
China
-one
-two
From above sample menu of a radTreeListView, user should be allowed to select only
UK, USA or China. OR London, Newcastle, Liverpool, OR Newcastle 1, Newcastle 2, Newcastle 3 BUT NOT Newcastle 1, London 1, UK ALSO NOT UK, Newcastle, Newcastle 1.
User should only select things/items at the same hierarchy. Basically, they should not select a parent and a child, THEY either select from parents or children or sub-children.
This is the control am using : http://www.telerik.com/help/silverlight/radtreelistview-overview.html

Presumably you have a TreeNode object that you stuff your objects into (you are displaying Country and City here). I would put a Nodelevel property on the TreeNode object and manage your SelectedItems collection using that property.
We use the HeirarchyID concept in our TreeNode that automatically knows it's level.
Take a read through some of Mr Smiths articles[^] I have quite a few bits of his code in my apps.

Hi Mycroft,
I use a TreeView (the excellent IntegralUI TreeView from Lidor Systems) that also has a "Level" property for every Node; it's very useful.
However, in this case, knowing the Level would not be adequate to determine which are "acceptable" selected nodes: "-california" and "-liverpool," for example, are at the same level; while that may have some "historic poetic truth" in terms of the music scene  ... that would not work for the OP.

Ok now I see where you are coming from, however I would bet the OP (coming from Uganda) may have considered california a city rather than a state. Certainly I did not pick it up until you pointed it out

I don't use the Telerik Treeview (I use one from Lidor Systems), so I don't know exactly what special features ... compared to any other Control ... it offers, or the exact syntax of Events it exposes, but this is pretty simple to do.
The Microsoft TreeView does not, of course, offer multiple selection, but the following code for the MS TreeView will demonstrate a general solution:
TreeNode firstSelectedNode;
TreeNode firstSelectedNodeParent;
private void treeView1_BeforeSelect(object sender, TreeViewCancelEventArgs e)
{
if (firstSelectedNode == null)
{
firstSelectedNode = e.Node;
firstSelectedNodeParent = firstSelectedNode.Parent;
}
else
{
if (e.Node.Parent != firstSelectedNodeParent) e.Cancel = true;
}
}
This code will confine selection to the sibling nodes of the first selected TreeNode. Obviously, in real-world use, you will need to reset the variable 'firstSelectedNode to null after you have "handled" the current selection.

i should find the length of days in the array but in my code |--- Date 1 ---|
|--- Date 2 ---| dont calculate in right way

ok i will explain in this way you worked from
DateTime[] start = new DateTime[] { new DateTime(2000, 1, 1), new DateTime(2004, 1, 1), new DateTime(2004, 1, 1), new DateTime(2008, 1, 1) };
to
DateTime[] end = new DateTime[] { new DateTime(2002, 1, 1), new DateTime(2006, 1, 1), new DateTime(2006, 1, 1), new DateTime(2010, 1, 1) };
and find how long you worked from 200years to 2010? as you see here i have overlap datetime and when i calculate in my program the lenght of working days i found it is not true
did you understand now?

hi Guys....
i have a programm and its about Human Resource managment...(c# and linq)
My Problem is :
i have 2 form ...: frmPersonals.cs and frmRPersonals.cs
the first one( frmPersonals) is for input data and save it to DB. and as you will see there is an image box in it(image of person will be save and retrieve on it)
the second form(frmRPersonals) is for search the DB (filter by user request).and it search Db and use "report Viewer" to show it.
my request is here:
i want to add the same image box (like first form) and put it in my Second form(frmRPersonals)so when it find the proper person it show his-her picture in this form...(in other word i want code that do the same things in my first form means:retreive the image of filtered personT in image box that will be put in frmRPersonals)...
how can i do that...plz do this for me in my source code....god bless u!
i will upload my whole source code ....plz help me i need it.

I suggest you read the guidelines on how to ask a question. Good luck with your homework.

Store the image in the database along with the rest of the person's details. There are plenty of samples around that show how to do it.
BTW no one is going to download your source code and rework it for you.

1. Your post is against about every rule in the guideline. Please read them first. (first forum post on top)
2. Don't provide download links like that, we don't know you and don't trust strangers.
3. Don't do txt spch. They're is an entire dictionary at your disposal, use full sentences and full words. It is a token of respect for one another.
4. No one will fix things for you. We will help you with a specific problem so you can fix it yourself. If you need coding done for you there are other sites for that.
5. "god bless u" Suppose, for a brief moment, I believe in such an entity, why would he bless me and what gives you the power or the right to make that claim for said entity? (OK, here I'm joking, but keep "faith" related expressions out posts, unless it is in the soapbox)
Despite the replies you received so far, no one is "against" you, nor is it personal, just step in line with the forum's way of working and you 'll be just fine.
