If you bought this over $1000 USD software package, and don't know how to drag-drop a Control into a Form and set its Properties, you should look for another type of work. If you didn't buy it, then you should not be using it.

i have a project about K-means clustering algorithm in C#: GitHub - muhammedtanriverdi/K_mean_Clustering: K-means Clustering Algorithm in C#[^]
And i have some source code about Heap Sort : Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.[^]
Now i want to Integrated this Heap Sort src code with that K-means project. I dont know where to add that Heap code in my project. Or change any code from K-means or something like that. Please help thank u so much

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Even if we did, we have no idea what question your teacher has set, so we have no idea why you want to include a heap sort into existing K-means code.

The only way to do that would be: understand each bit of code, and think about what you are trying to achieve. Try it yourself, you may find it is not as difficult as you think! Just grabbing bits of code from the internet and slamming them together is like assuming you can use the wheels from any vehicle to replace the ones on your car: some will not fit on the hub (four bolts instead of five), some won't fit under the wheel arches as they are too wide, others won't fit because they are too tall. You need to look carefully at the car and at potential wheels in order to determine if they can be fitted and if so what you need to do to fit them.

A much better solution is to write your own code instead of trying to hand in somebody else's and risking plagiarism allegations...

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

BitConverter.ToString with customizable length?

10-Dec-18 20:21

If you mean "tell me where to start to bolt these two together" then I already did:

If you mean "how do I start to do it for myself?" then that's just the same as any other coding homework you have been given: read the question carefully, research the algorithms (which are not code) you need, write yourself a specification (so you know exactly what you are working towards), expand that to a design, and then code and test. I can't even see your homework question, so I can't be any more specific than that!

Re: BitConverter.ToString with customizable length?

10-Dec-18 2:46

Hi guys,

I am working in something new and I would like to write a binary file with fields of different length, being it 2, 4, 8 bytes mostly.

I already get the desired conversion for doubles with

double dTest_max = 15.020245207;
byte[] bytesDouble_max = BitConverter.GetBytes(dTest_max);
Console.WriteLine("Hexa Double MAX (byte[]) = 0x" + BitConverter.ToString(bytesDouble_max).Replace("-", ""));

//output = 0x95D626E80B2E113E

Using the same with the integer "312" gives me: output = 0x38010000

If I cast the int to long I do get my desired: output = 0x380100000000

But as the desired length of the parameter in the binary telegram is fixed by header (dynamic) I would like to avoid having to evaluate the respective length of the actual parameter to choose if I have to cast it or not.

Is there any hidden function / method in .Net that could do that?
I mean something like:

Console.WriteLine("0x"+int.ToString("X")); //gives 0x138
Console.WriteLine("0x"+int.ToString("X12")); //gives 0x138000000000

But for the BitConverter?

I have already had a look to: BitConverter Class (System) | Microsoft Docs[^] and its overloads, but the "start" and "length" are only to be used if the data input is an array, and haven't seen anything to determine the length of the output

If not... I am already thinking to use workarounds like filling bytes[] with different fixed lengths and then replacing only the bytes given by the conversion.

Using int.ToString("X12") and the "reversing" it would do the job too, but I am not sure if that would be reliable enough for my use case.

No, there isn't - ToString is a presentation function, so it adds a lot of formatting so you can present your data in "user friendly" formats depending on how they need to view the data.
But an integer only has one size: 32 bits. And a long is always 64 bits - so BitConverter will always reflect that.
However, this might be of use to you: ByteArrayBuilder - a StringBuilder for Bytes[^]

I will shorten my days by 8 hours; that'll get you your 30. Time is moving too slowly for me these days.

You do realize that any "open source" project you try to hand in will not look anything like the code you've been turning in? You're going to be immediately called out for not doing your own work and will fail the class on the spot or lose your job.
