c# - Best way to test if a Type is a collection -

-

I have a method that accepts the parameter obj type of system. Object

Now I want to know whether the actual type is obj:

  • A collection type (IEnumerable).
  • Anything else

The first method I have thought of: 

  if obj is (isnumerable) // obj is a collection

But System.String implements IEnumerable, and I do not want to treat string as a collection .

The way I thought it was a test for icocolon instead of ininmereble, because IEnumerable is more than a possible archive, a real one leaves this string out, but it also shows Icon-Off-T This is because it does not inherit IClippin (the nominal cable T-T is only compatible with the general collection abstraction that is compatible with the rear - it receives the INIMRAMABLE).

So I think the best way is this: 

  if (obj string is) // if there is no archive (oz is IEnumerable) // archive th / No collections

Is there a better way?

I think you are making it a bit confusing. If you really want to use IEnumerable, but leave the system. String, why not directly into the code?

Public Stable Bull Isylation (Object OBJE) {Reserve Obje Inimarable & amp; ! (Obj is string); }

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
