c# - How to know when a response has finished being sent to the client? -


i have web api web method returns list of events in xml:

public ilist<event> getallevents() { ... }  public class event {     public string name { get; set; }      public int id { get; set; } }

the client may send request , receive 100 events serialized happens that:

  • request received getallevents methods
  • data provided method
  • web api engine serializes object xml
  • web api engine sends serialized data (it might e.g. 5mb) client

the whole process may take e.g. 5 seconds.

i'd able log time when web api engine finishes sending serialized data client.

how achieve this?

what trying achieve here?

based on return type of action, web api creates content called objectcontent uses formatters serialize response.

for objectcontents, default, web api hosting layers 'buffer' entire response before starts sending buffered data on wire.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
