Need help with a C# Programm

[RockiLocky]

Hello guys,

 

so to start some background. Right now I am going to a kinda High school and need help with a program for beginners (that's what I think it is , expect the part were I get fucked) we are doing right now. What we need to do is to create a calculator with different actions to do. Now the actions are not really the problem till yet, the main problem is that he wants us to do a kind of Registry. For example if we type in the number x = 128 and we use the Registry Signed 8Bit that we get a overflow and it is -128 if I am correct what happens. 

 

 

So the question is how to do that

 

Well to begin with I tried it in a Console application just reading in a value, then doing this:

 

Int64 x = Convert.ToInt64(ReadLine());

 

well then I tried to change it for example to Signed 8bit, so I did this:

 

var y = Convert.ToIntSByte(x);                                  //I wrote var because this variable would be in an if() or switch(), so I can change it to the correct Type I want

 

 

Well that didn't work, so now I am here I hope you guys can help me. Code and stuff is down there if you got questions ask them, I know comments are in german but if you need it translated ask them as said

Btw I was looking to implement it in the class so I have less coding on the MainWindow!!

 

Hope you guys can help me out,

 

Regards Rocky

Yes I just realized Unsigned 65Bit I changed it don't worry

 

SL and SR stand for Sift Right and Shift left

I believe you're looking for

var y = (SByte) x;

I believe you're looking for

var y = (SByte) x;

 

Is there no other way because I will need to get something so I can still use my Base system

the example is what is also in my code;

 

mZ1 = Convert.ToInt32(value, 2);

You should put some thought into improving your design. You are doing this in WPF, you should really be implementing it in accordance with the MVVM design pattern.

Honestly what you have right now is nasty.

I'm not sure what you're looking for. Convert.ToSByte, and all other Convert methods will throw an OverflowException. They are all internally using a cast like how I showed you. For example, here's how Convert.ToSByte is implemented.

[CLSCompliant(false)]public static sbyte ToSByte(long value) {    if (value < SByte.MinValue || value > SByte.MaxValue) throw new OverflowException(Environment.GetResourceString("Overflow_SByte"));     Contract.EndContractBlock();    return (sbyte)value; } 

As you can see, the method does (sbyte)value, which is what I showed you, but it also does the overflow check which you don't want.

Thats bad to hear, but we need to do it in WPF

Ok I understand you now. The thing was before that I used the Convert.ToXXY() Function to easily work with Hex and Bin, because I don't only have Dez so yeah, but will do that manually. Thx for the help

I think you may have missed the point a little bit. MVVM is a design pattern that complements WPF. It's about the separation of the View (UI), Model (data model or computational model) and the VIewModel (the layer of business logic or whatever orchestrates things). No layer 'knows' anything about any other layer and they interact via various abstraction methodologies.
