C# How to get Konsole output into files like this assignments?

Jul 22 2022 1:08 PM

Hello

I'm currently learning C# and I have a learning task that I can't quite solve.

Is there someone in the forum who can look through my task and help me with the solution?

Here the two assignments:

For this submission task, create a new project "ESA_Project" in which you copy the latest status of the aircraft project. Complete the project with a Programming that logs a flight's position data to a file can become.

  • The log file should be placed in the executable folder of the program ("Release" or "Debug") can be written
  • The name of each log file should follow the pattern 
  • _---.bin
    be assembled. This can be generated and differentiated programmatically reliably multiple log files with this time-dependent encoding.
  • A string containing the following information should first be written to the file summarizes:
  • Flight "" (type "") departs from position "--" with target position "--".
  • This is the header of the log file, which is then followed by the data.
  • Again, all expressions with angle brackets are replaced by concrete ones Replace values from programming.
  • The x, y and h data of the current position are then to be added to the file be written as int values until the flight is complete. These are, so to speak the data of the file.
  • The logging should be made dependent on the value of a "switch", which you define as a static variable in the Program class:

public static bool log = true;

  • When this switch is set to true, logging occurs when it is set to false is not logged.
  • This task is not only about the technical realization of the aforementioned Requirements, but mainly to fundamental considerations object-oriented Programming. You should e.g. B. If you have the necessary writer declare, make it clear that a writer corresponds to a flight recorder and check which type of aircraft can use a flight recorder at all. examples for such considerations of object-oriented planning there was in this issue, but also when planning the project in the study booklet CSH01B - e.g. B. to settlement of the transponder.

Based on these considerations, the following questions need to be answered:

1a. Where do you declare the Writer object so that it is in the places in the program where you want it to be to whom it is needed is also known?

1b.At what point in the program do you assemble the file path, create the writer and write the header?

1c. Where in the program do you write the data for the x, y, and h values?

1d. At what point in the program do you close the writer?

1e. In each case, how do you ensure that these operations only take place if the "switch" in the program class is set to true?

Enter the program code in each case and briefly explain your programming.

A notice:

BinaryWriter knows a method
public virtual void Write ( string value )
... which not only writes the string to be specified as a parameter to the file, but before that stores information about the length of the string (compare the .NET documentation).

BinaryReader knows a mirror image method
public virtual string ReadString ()
... which first evaluates the length information stored in the binary file and then precisely reads the length of the string that follows, so that the read pointer for further read operations is set exactly to the following byte.


2. Add in the program class FliegerProject (for submission task 3) a method 

public void ESA4Out(string logpath)

My name for this:  public void ProtocolOutput(string protokoll)
This method aims to generate the binary of a flight using programming in ESA 3 is created, read back and output its content to the console. As a result this could look like in Fig. G.1 for two flights:


Add calls to this "ESA4Out" method at the end of the program control in "program bars". So that the "ESA4Out" method always outputs the last logged flight save the path to its log file in a new property, which is only equipped with a get accessor for retrieval. This Property is created where the logging also takes place. My ESA4Out Method is named ProtokollAusgeben.
When programming "ESA4Out" the internal file structure is the log file should be noted, so that in the console first the header and then the flight data be issued. The flight dates begin with the start and end with the reached target position. Because of the rough timing and the resulting rough Position calculations are the specified and the actually reached target position
differ from each other. Explain the main steps of your solution with code snippets.

And here the content of the 2 files that are required (debug folder) to start the program.
The files  are simple textfiles and must be named:

LH 3000.init

targetPos.x=1000
targetPos.y=500
targetPos.h=200
distancePerBeat=160
altitude=350
risePerBeat=25
riseDownPerBeat=15
typ=4
seats=290

LH 500.init

targetPos.x=1000
targetPos.y=500
targetPos.h=200
distancePerBeat=200
altitude=300
risePerBeat=20
riseDownPerBeat=10
typ=3
seats=250
