I want to have the user input length and width so that we can calculate the area of the rectangle. I have two classes which are Program and Rectangle. The problem is when I try to run this code there is an error:
Program has more than one entry point
How to fix this problem?
Here is my code:
using System;
using System.Collections.Generic;
namespace rec_oop_20211025_E3
{
class Program
{
static void Main(string[] args)
{
List<Rectangle> recs = new List<Rectangle>();
ConsoleColor errColor = ConsoleColor.DarkRed; // to make the error part red in color
ConsoleColor defColor = Console.BackgroundColor; // defColor is default color
start: // use start to run many times
Console.Write("Input sides (eg. 5,6): ");
string line = Console.ReadLine();
Rectangle rec = new Rectangle();
try
{
rec.SetSides(line, ",");
Console.WriteLine($"{rec.GetInfo()}");
recs.Add(rec);
}
catch(Exception ex)
{
Console.BackgroundColor = errColor;
Console.WriteLine($"Error > {ex.Message}");
Console.BackgroundColor = defColor;
}
Console.WriteLine("\nEsc to stop, any key for another rectangle...");
char key = Console.ReadKey(true).KeyChar; // with start we need this
if (key != (char)ConsoleKey.Escape)
goto start;
Console.WriteLine();
Console.BackgroundColor = ConsoleColor.DarkGreen;
double total = 0;
foreach(var r in recs)
{
total += r.GetArea();
Console.WriteLine(r.GetInfo());
}
Console.BackgroundColor = ConsoleColor.DarkBlue;
Console.WriteLine($"\nTotal = {total:n3}");
Console.BackgroundColor = defColor;
}
}
public class Rectangle
{
//static methods
public static void CheckSides(double width, double length)
{
if (width < 0 || length < 0)
throw new Exception($"Rectangle sides( {width}, {length}) are invalid.");
}
public static void TryParse(string data, string delimiter, out double width, out double length)
{
try
{
string[] arr = data.Split(delimiter);
width = double.Parse(arr[0]);
length = double.Parse(arr[1]);
}
catch (Exception)
{
throw new Exception($"Given data \"{data}\" are invalid.");
}
}
//intance fields
private double wd;
private double lng;
//instance methods
public void SetSides(string data, string delimiter)
{
double width, length;
Rectangle.TryParse(data, delimiter, out width, out length);
Rectangle.CheckSides(width, length);
wd = width;
lng = length;
}
public string GetInfo() => $"width={wd}, length={lng} > area={GetArea():n3}";
//public double GetArea() { return wd * lng; }
public double GetArea() => wd * lng;
}
}
}
This is what is this - error is very descriptive. Try search (Ctrl + shift + F) for Main( (just this text main and then 1 round bracket) - you should find another function hidden somewhere that define void Main - this could not be. Only 1 static void Main() could exist. Delete the other one and now you app could compile. Does not matter if you have other classes - the only thing is matter is that function named Main could be only one
P.S. If my answer is not enough - and you still have some question - please make a bare minimum clone of your code and make it Github repo - so we could look at the code
You can check the official documentation on this error:
To resolve this error, you can either delete all Main methods in your code, except one, or you can use the StartupObject compiler option to specify which Main method you want to use.
You can alternatively use the /main switch on the command line to indicate the type containing the appropriate entry point.

so we can give any number of parameters to a method, like this:
static int sumPrices(params int[] prices) {
int sum = 0;
for (int i = 0; i < prices.Length; i++) {
sum += prices[i];
}
return sum;
}
static void Main(string[] args)
{
int total = sumPrices(100, 50, 200, 350);
Console.WriteLine(total);
Console.ReadKey();
}
but ... what if we wanted to get the "100, 50, 200, 350" from the USER?
in above example it's the coder giving the sumPrices method its arguments/parameters.
i mean, it would be one solution to just pass the method an array.
static int sumPrices(int[] prices) {
int sum = 0;
for (int i = 0; i < prices.Length; i++) {
sum += prices[i];
}
return sum;
}
static void Main(string[] args)
{
//get up to 9999 inputs and sum them using a method
bool whileLoop = true;
int[] inputs = new int[9999];
int index = 0;
while (whileLoop == true)
{
Console.WriteLine("entering price #" + index + ", type 'stop' to sum prices");
string check = Console.ReadLine();
if (check == "stop") {
whileLoop = false;
break;
}
inputs[index] = int.Parse(check);
index++;
}
int[] prices = new int[index];
for (int i = 0; i < index; i++)
{
prices[i] = inputs[i];
}
Console.WriteLine("-----------------");
Console.WriteLine(sumPrices(prices));
Console.ReadKey();
}
BUT... longer code... and has limits.
our professor basically wanted the first code, however, i don't see how and where it's
supposed be used if we didn't know the user's inputs and if params arguments were coming from the coder (unless of course, coder using the same function multiple times for convenience)
i have tried to think of a solution and i'm not exactly sure how it could be done.
but it basically goes like this.
we could get inputs from the user separated by commas:
100,200,50
and the program would translate it into params arguments:
sumPrices("100,200,50");
but as you can see... it's a string. i wonder if there's a JSON.parse() thing like in js.
The code in the OP has some unnecessary code as well as some limitations such as 9999.
Let's examine the following code:
bool whileLoop = true;
while (whileLoop == true)
{
}
This could be re-written as:
while (true == true)
{
}
or
while (true)
{
}
Next, let's examine the following code:
if (check == "stop") {
whileLoop = false;
break;
}
You've set whileLoop = false; which is unnecessary because once break is executed, excution has moved to after the loop.
Since the input array has a hard-code size of 9999, you've limited yourself to 9999 values. You may consider using a List instead or resize the array.
Try the following:
using System;
using System.Collections.Generic;
using System.Linq;
namespace UserInputTest
{
internal class Program
{
static void Main(string[] args)
{
decimal price = 0;
List<decimal> _values = new List<decimal>();
if (args.Length == 0)
{
//prompts for user input
Console.WriteLine("The following program will sum the prices that are entered. To exit, type 'q'");
do
{
Console.Write("Please enter a price: ");
string userInput = Console.ReadLine();
if (userInput.ToLower() == "q")
break; //exit loop
else if (Decimal.TryParse(userInput, out price))
_values.Add(price); //if the user input can be converted to a decimal, add it to the list
else
Console.WriteLine($"Error: Invalid price ('{userInput}'). Please try again.");
} while (true);
}
else
{
//reads input from command-line arguments instead of prompting for user input
foreach (string arg in args)
{
if (Decimal.TryParse(arg, out price))
{
//if the user input can be converted to a decimal, add it to the list
_values.Add(price); //add
}
else
{
Console.WriteLine($"Error: Invalid price ('{arg}'). Exiting.");
Environment.Exit(-1);
}
}
}
Console.WriteLine($"\nThe sum is: {SumPrices(_values)}");
}
static decimal SumPrices(List<decimal> prices)
{
return prices.Sum(x => x);
}
static decimal SumPricesF(List<decimal> prices)
{
decimal sum = 0;
foreach (decimal price in prices)
sum += price;
return sum;
}
}
}

The trick is input from the user always starts out as strings. You must parse those strings into integers. We can do it in very little code like this:
static int sumPrices(IEnumerable<int> prices)
{
return prices.Sum();
}
static void Main(string[] args)
{
int total = sumPrices(args.Select(int.Parse));
Console.WriteLine(total);
Console.ReadKey();
}
See it here (with adjustments for the sandbox environment):
https://dotnetfiddle.net/Pv6B6e
Note this assumes a perfect typist. There is no error checking if a provided value will not parse.
But I doubt using linq operations are expected in an early school project, so we can expand this a little bit to only use techniques that are more familiar:
static int sumPrices(int[] prices)
{
int total = 0;
foreach(int price in prices)
{
total += price;
}
return total;
}
static void Main(string[] args)
{
int[] prices = new int[args.Length];
for(int i = 0; i<args.Length; i++)
{
prices[i] = int.Parse(args[i]);
}
int total = sumPrices(prices);
Console.WriteLine(total);
Console.ReadKey();
}
If you're also not allowed to use int.Parse() (which is nuts, but sometimes homework has odd constraints) you would keep everything else the same, but replace int.Parse() with your own ParseInt() method:
static int ParseInt(string input)
{
int exponent = 0;
int result = 0;
for(int i = input.Length -1; i>=0; i--)
{
result += ((int)(input[i]-'0') * (int)Math.Pow(10, exponent));
exponent++;
}
return result;
}
Again: there's no error checking here for things like out-of-bounds or non-numeric inputs, and this particular implementation only works for positive integers.
My program is supposed to take the two middle values of a word, in this case "es". I used a second variable to get "s" as the program would already collect "e" however, when I run this program the values returned are integers instead of letters.
using System;
using System.Linq;
class Program
{
public static void Main(string[] args)
{
string word = "Test";
int wordLength = word.Count();
if (wordLength % 2 == 0)
{
int middle = word[wordLength / 2];
int nextAlong = middle + 1;
Console.WriteLine("Even number");
Console.WriteLine("{0},{1}", middle, nextAlong);
}
else
{
Console.WriteLine("Odd number");
Console.WriteLine(word[wordLength / 2]);
}
}
}
The console output is
Even number
115,116
Indexing into a string does return a char but because you’ve defined the middle and nextAlong variables as being of type int, they’re getting implicitly converted from char to int.
Try the following instead.
public static void Main( )
{
string word = "Test";
int wordLength = word.Length;
if (wordLength % 2 == 0)
{
var middleIndex = wordLength / 2 - 1;
char middle = word[middleIndex];
char nextAlong = word[middleIndex + 1];
Console.WriteLine("Even number");
Console.WriteLine($"{middle},{nextAlong}");
}
else
{
Console.WriteLine("Odd number");
Console.WriteLine(word[wordLength / 2]);
}
}
Now if you run this it does not output each Console.WriteLine in one line, why?
I know console.writeline goes to next line when done but the problem is it jumps to next line while printing when it print the exception var it is not in the same line as the rest of the writeline
The error occurs inside the Display() function at the number 6 variable (exception) it is not in the same line as the rest of the writeline, why?
And also there are no line breaks where the error ocurs.
Ans can be any number you like.

Because you set exception = "\ncomplete"; at different places. The \n at the beginning is a new line character.
Remove the \n
exception = "complete";
Same problem with other texts like "\nSolution Found!".
Using string interpolation makes string formatting more readable:
Replace
Console.WriteLine("Pref:{0} Next:{1} Step:{2} Formul:{3} x:{4} Ans:{5} Status:{6}",
pref, next, stepval, formul, x, ans, exception);
by
Console.WriteLine(
$"Pref:{pref} Next:{next} Step:{stepval} Formul:{formul} x:{x} Ans:{ans} Status:{exception}");
WriteLine writes in a New Line. You should try
Console.Write()
If you want to print right after your previous print.
The value to your variable exception is the reason why the console is printing on a different basically if you put a special character \n means new line hence all the methods you are calling have this special character.
Solution remove special characters and use the Console.WriteLine or Console.Write methods
As per the code provided you have not called the method i made some changes to the code

How to convert a column number (eg. 127) into an excel column (eg. AA)
Ok so I am writing a method which accepts a 2d array as a parameter. I want to put this 2d array onto an Excel worksheet but I need to work out the final cell location. I can get the height easily enough like so:
var height = data.GetLength(1); //`data` is the name of my 2d array
This gives me my Y axis but it's not so easy to get my X axis. Obviously I can get the number like so:
var width = data.GetLength(0);
This gives me a number, which I want to convert to a letter. So, for example, 0 is A, 1 is B and so on until we get to 26 which goes back to A again. I am sure that there is a simple way to do this but I have a total mental block.
What would you do?
Thanks
Here's a version that also handles two-letter columns (after column Z):
static string GetColumnName(int index)
{
const string letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
var value = "";
if (index >= letters.Length)
value += letters[index / letters.Length - 1];
value += letters[index % letters.Length];
return value;
}
Just cast it to a char and do "ToString()".
using System;
using System.Collections.Generic;
public class MyClass
{
public static void RunSnippet()

int myNumber = 65;
string myLetter = ((char) myNumber).ToString();
WL(myLetter);

Edit: After getting five downvotes but no comments saying anything about why, I've tried to reformulate the question. I can only assume the votes are because people see a lot of text and maybe think there isn't even a question in here.
I've written code that (mis)behaves rather strangely. It seems the code doesn't run the same way on other's computers, so please don't get mad at me if you can't reproduce the problem.
I had a look, just for fun, at the frequencies with which different bytes occur in GUIDs. I had noticed that the string representations of guids always contained "4". Rather than read about it on Wikipedia I tried to think about what it might be, as it can be fun to do a little "original research" and do your own thinking once in a while. (And then read the wiki afterwards!)
The strange issue on my machine happens when I try to use the "burst" feature. Provided it is reproducible in your environment, you can re-create it by running the app and hitting B. This is supposed to result in a burst of 100 steps (i.e. make 100 new guids, updating the displayed frequencies only at the end of the burst, because writing to the console is so ridiculously slow). But it actually results in just a single step!
I set a breakpoint in ProcessKey() where the burst variable is assigned. When I step out of the method, I notice in Debug Output that a thread exits. This is not a coincidence; it happens reliably every time. Then my watches show me the burst variable that was just assigned to 1000 in the previous step... has value 0.
Why does this happen? Did I do something wrong? I notice there is no attribute anywhere specifying STA, but I've never really had a clue what these things are anyway and I haven't removed anything from the console application template I used (with VS-2011 developer preview, though unlike Redmond I live in 2012 now)...
Finally: The app moves the cursor back and overwrites the text again and again. This doesn't work well if you can't make the console window high enough to show all the output at once, so you may want to fiddle with the console font (or change the width of the console, the app should change accordingly though I haven't tested). The pattern becomes completely regular (on my machine at least!) with a 4-column output (if your console is 80 chars wide you'll get 4 columns).

Ehem. I tried running the code at my HTPC, a different computer from the one I coded this on, and now I cannot reproduce the problem. That is, I do observe the burst leading to just a step, but that is due to a logical error in my code (when the report interval is reached it sets burst to -1). It's hard to believe I did not set my breakpoint, stepped through, and saw the variable get destroyed, because I know how weird that would be and tried several times to be sure I saw what I thought I saw. But it's also hard to believe I had stumbled upon such a weird and deep bug in the framework/clr, especially considering that my code had a bug that causes the thing that got me attaching the debugger in the first place..
In any case, I'll mark it as closed. And post the revised code here if anyone wants to play with it. I've fixed the bug and made the output a bit more compact so it works better on less generous screens than the 22" full-HD_one I did this on. It now uses 8 columns regardless of the console width, on the probably safe assumption that most people use standard 80-char width, into which 8 columns now fit.
If anyone would care run this and post their findings (just press P to quickly get stable frequencies, the step/burst thing is for silly stuff like seeing what the distribution looks like after fewer generations). On my HTPC, I get this result:
0x00 - 0x3f 0.34%
0x40 - 0x4f 0.73%
0x50 - 0x7f 0.34%
0x80 - 0xbf 0.44%
0xc0 - 0xff 0.34%
This means: Bytes 0x00 to 0x3f each made up 0.34% of all the bytes in all the guids generated (509,194 in this particular case, but I get this result every time with more than 100,000 guids or so). There are 3 very distinct groups, and maybe if I now go and read about Guids on wikipedia I will understand why that is. But it wouldn't be as much fun to do this if my "discovery" was something I knew before I began. :)
