c# - Best practices for serializing objects to a custom string format for use in an output file -

-

About to apply override of toasting () on a particular business category, to create an Excel friendly format Was written in an output file, which will be picked up later and processed. What is the data given here: 

  5555555 "LASTN SR, FIRSTN" 5555555555 13956 STREET RD TOWNSVILLE MI 48890 25.88 01-003-06-0934

This is not just a big deal for me to create a format string and override ToString () , but it changes the behavior of ToString () for any object Now, I am studying, and to implement a class, it looks like a way tostring () > Good idea, but I am still I am a bit confused about whether it should be located where all logic and format class to be created.

When you need to CSV, tab-delimited or create, what do you do with any other non-XML straight from an object?

Here is a normal fashion for creating CSV. A list of items, reflection use: 

  public static string toCsv & l; T & gt; (String separator, INMEMERABLE & lt; T & gt; item list) {type T = typef (T); Fieldinfo [] field = t. Gatfield (); String Header = String .joint (Segmentation, Field. Select (F => f.Name) .Oir ()); Stringbilder csvdata = new stringbilder (); Csvdata.AppendLine (header); Foreach (var o in object) csvdata.AppendLine (ToCsvFields (Separator, Field, O)); Return csvdata.ToString (); } Public Fixed String ToCsvFields (string separator, FieldInfo [] field, object o) {StringBuilder linie = New StringBuilder (); Foreach (var f in fields) {if (linie.Length> gt; linie.Append (separator); Var x = f.GetValue (o); If (x! = Zero) linie.Append (x.ToString ()); } Return linie.ToString (); }

There may be several variations, such as writing files directly to ToCsv (), or changing stringbilders with an IEnumerable and yield statement.

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...

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...
