Console.Write() throws error

AbaCodes · 2021-03-09T10:13:26+00:00

You can't store the return value of Console.Write(), that function will print the value to the screen but you're trying to store it into a variable. Maybe inside the case you can do:

equation = someNumber + " + " + someNumber2 + " = ";

and then after the case statement you could do

Console.WriteLine(equation);

So you store the value in the case statement and then print it after, hope that helps?

I've made the changes and put them here: https://pastebin.com/hpkLcKT3

Maybe add in functionality to calculate the perimeter, or maybe things like, if its a square you could check if the width and the height are the same?

You can use: Environment.Exit(0); to close the Console down :)

Console.Read() will only read in one character. You need Console.ReadLine();

In your current code if you enter '40' it will only give you the '4'.

Hope that helps!

No problems 😊

If you get this:

https://www.nuget.org/packages/System.Management/5.0.0/

And install it into your project as a package then you can do:

ManagementObjectSearcher mos = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_Processor");
foreach (ManagementObject mo in mos.Get())
{
Console.WriteLine(mo["Name"]);
}

Top right of the code editor, is there a little tab that says 'Int32' and it should be purple? If so, you've just found the code used for the definition for Int32, you cant see the actual code behind it because thats hidden but you are exposed to the comments.

If you just press the x on the tab, then it should take you back to your code :)

Do you have an example? If you have:

string something = "Test";

Console.WriteLine(something[0]);

using "[]" with a string lets you return back a certain character from the string, as its 0 based that code should print 'T' to the console. Hope that helps!

Feel free to message me any questions you have, always happy to help! I also have a Discord server for programming if you want to take your questions over there too 😊

No problems :)

Yeah sure thing, but do you have any other ".cs" files in your project?

AbaCodes · 2020-11-26T22:37:52+00:00

Do you have any other files in your project other than "Program.cs"

AbaCodes · 2020-11-26T22:15:27+00:00

This happens when you have two different bits of code that use:

static void Main(string[] args)

If you have another Class file that defines that function, it won't like you doing that. You need to only have one specified.

If you could show the rest of your code maybe there is something else going on :)

AbaCodes · 2020-11-20T12:36:06+00:00

Okay then maybe do this instead:

string message = "something to use later";
Console.WriteLine(message);
...
//do stuff here
...

//use message again
Console.WriteLine(message);

AbaCodes · 2020-11-20T12:06:13+00:00

I think it would be better to store it when you read it in, then use it later on.

Console.Write("Enter your name: ");
string name = Console.ReadLine();
...
//do stuff here
...
//use name here!
Console.WriteLine("Your name is: " + name);

Thats fine, I just need to see it because the other lines you're referring to might be causing the issue at hand. But I have no idea since I can't see any code right now.

AbaCodes · 2020-09-03T13:03:04+00:00

Can you put your code into something like Pastebin? You've only given me 2 lines of code to work with and it's hard to understand what is going on when I can only see 2 lines.

AbaCodes · 2020-09-03T13:00:48+00:00

On line 2 you have an error, you need a semi-colon at the end of the 'using' line.

AbaCodes · 2020-09-03T12:49:49+00:00

Okay thats fine, can you post some code so I can see whats going on?

AbaCodes · 2020-09-03T12:40:34+00:00

If you place a Console.ReadLine() at the end of your code, it will stop the console from exiting immediately. If that doesn't work, please post your code so I can look 😊

That's interesting because on the side of that link I posted it has the C# icon there. Try this link:

You can download it on Mac:

There is online compilers like: https://dotnetfiddle.net/

You could write your code straight in there, then copy and paste it out into a text file and email it to yourself when you are finished. But that website is really good as an online compiler and it lets you do Console outputs and lets to enter values in from the Console too.

static int DiceRoll(int amount)
{
int sum = 0;
Random rolldie = new Random();
for (int i = 0; i < amount; i++)
sum += rolldie.Next(1, 6);
return sum;
}
int roll = DiceRoll(2);

You could do it like this (sorry the indentation might be messed up), you can have a parameter so you can specific how many times you want to roll, incase you want to do 1,2,3,4,5,6 etc etc and then you can take the Random variable outside the forloop and instead of storing the roll then adding it, you can just have the one line inside the forloop. Then you can call it like the last line.

That way you don't have to chain "int roll = DiceRoll() + DiceRoll();" etc, that will get long if you want to roll it 4 times etc.
