.net - Regex that matches a newline (\n) in C# -

-

OK, this is driving me crazy .... I have a string that is made like this:

var newContent = string.Format ("({0}) \ n {1}", tampered content, answer)

New content will be displayed:
(old text) New text

I need a regular expression which removes the text between brackets with brackets and the text with new letters.

The best I can come up with is:

const string regex = @ "^ (\ (. * \) \ S)? (? & Quot; Capture & Gt ;. *) "; Var Match = Reggae Match (original_content, regex); Var stripped_content = match Group ["capture"]. Values;

This works, but I want to match the new line ( \ n ) specifically, any empty space ( \ s ) is not changing with \ s with \ n \\ n or \\\ n Does not work.

Please help capture my discretion!

Edit: An example: 

  public string reply (string old, string new) {const string regex = @ "^ (\ (* \)) .)? (& Quot; capture & gt ;. *) "; Var Match = Reggae Match (old, reggae); Var stripped_content = match Group ["capture"]. Values; Var result = string.format ("({0}) \ n {1}", teased content, new); Return result; } Answer ("(message one) \ nmessageTwo", "messageThree"): (messageTwo) message three

If you specify RegexOptions.Multiline, you can use ^ and $ to match the start and end of a line, respectively Are there.

If you do not want to use this option, then remember that a new row can be any of the following: \ n , \ r < / Code>, \ r \ N , so instead of just looking for \ n , you might want to use something like this: [\ n \ r] + , or more at all: (\ n | \ r \ n \ r \ n) .

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...

c - Linux mmap() error -

I have a memory map file, out of which I want to parse the content of the buffer. MMAP () achieves success, and I can successfully use fprintf to print the buffer content in the file. However, when I try to access Buffer as an array in my program directly, I get a partition error. Why is this happening? Here's the code: #define PTT_DUMP "/ home / druru / somefile". .
