Try:
var x = list.GroupBy(g => g.Key).Select(grp => grp.Skip(1)).SelectMany(i => i);

You need a small tweak to get a one-off instance like 'baz in the result:
var x = list.GroupBy(g => g.Key).Select(grp =>
grp.Count() == 1
? grp
: grp.Skip(1)).SelectMany(i => i);

Yes, but his original question specifically excluded "baz".

I know how to show a UserControl(WPF) by ElementHost in
a form.
like this:
private ElementHost m_elementHost;
private UserControl1 m_uc;
private void button1_Click(object sender, EventArgs e)
{
m_elementHost.Child = m_uc;
}
but I want to do show UserControl1 not use ElementHost, like this:
private void button1_Click(object sender, EventArgs e)
{
UserControl1 uc = new UserControl1();
uc.Show();
}
|

|
|
If you're asking how to show a WPF UserControl in a Windows Forms app without using ElementHost, you can't. ElementHost is required.
|
|
|
|
|
|
Stick the user control in a WPF Window; then you can "show" it. Hide the window's "chrome" if that's a problem. Same result.

I am running a Windows Service that executes successfully every 10 minutes. It instantiates an in house dll file and calls a method to do some process. This dll file logs everything throughout the process. Now the problem is I have no clue where this log file is anymore!!
Normally when we use this dll file and call its methods, it will create a folder called "Custom" inside the application path with log files.
I do not see any Custom folder anymore even tho my code runs and I see the results.
How do I find where my dll related log files are?

Hi,
I don't think the DLL file is relevant, services use their own default directory and any DLL they reference would use the same. I guess this[^] will offer more than you are asking for...
|
|
|
|

Hi,
Thanks for your reply. The registry key only holds the path for the service executable file. And I already know where my service has been installed. I can also see the dell files in there. But I do not see the custom folder and log files that the dll file is generating. They are not in that path.

Hi,
to make sure what file operations are executed, use Process Monitor[^] as Dave already suggested.
My best guess is this: as a service, your code is using C:\Windows\system32 as its default directory; and it won't have sufficient privileges to create a folder or file there, so nothing gets created, and the exceptions got caught and swallowed (which is always a bad idea). If correct, I suggest you set another default path before calling your DLL, using a location that is not full of system files.
|
|
|
|
|
You can use ProcMon[^] to watch the file operations of your service.
|
|
|
|
|
It is difficult to say anything without seeing your code. It depends on how your code resolves the path.
Program Files folder is generally not accessible to programs and services, you'd have to write log files to User Profile Directory which is usually C:\Users\<username>\AppData.

Search for the file name / mod dates on the drive and / or in program data or user data.
Have a coffee and let it search.
(Check the Windows / custom app "event" logs).
