How would I go about calling a function from another class in a if statement. For example i have a menu and I want to be able to to display the user choice:
namespace _5049COMP_OO
{
class Interface
{
public string menuChoice;
//This creates the loadup menu.
public void menu()
{
DrawLine();
Console.Write(" Welcome to BOSS eAuctions! ");
DrawLine();
Console.WriteLine("1. Browse");
Console.WriteLine("2. Login");
Console.WriteLine("3. Register");
Console.WriteLine(" ");
Console.WriteLine(" ");
Console.WriteLine(" ");
Console.WriteLine("4. Quit ");
DrawLine();
Console.Write("Please select on of the options:");
menuChoice = Console.ReadLine();
DrawLine();
}
// Create the login menu
public void LoginMenu(string username, string password)
{
DrawLine();
Console.Write(" Login! ");
DrawLine();
Console.WriteLine("Username:");
Console.WriteLine("Password");
username = Console.ReadLine();
password = Console.ReadLine();
DrawLine();
DrawLine();
}
I want the statment in "Public void Choice()
namespace _5049COMP_OO
{
class Functions
{
public void Choice()
{
}
}
}
You need an instance of the class or it needs to be a static method.
At the top of your Interface file, add a using statement for the Functions namespace.
If you make Choice() a static method, you can do
Functions.Choice();
Otherwise you'll need
var f = new Functions();
f.Choice();

What am i doing wrong? I am trying to have my program read the data from a csv file but i keep getting this unhandled exception, is it because of how i wrote the txt file? the exception?
First I tried to have the data be displayed as a list in the console, but that did not happened either. I cant seem to be able to do that here or even get it right to read from my txt file.

Just started kearning c#, and I have been having some trouble when running the console application. For some reason, when I run the console application, it runs the sayHello method, but won't run the Arithmetic method.
Any help would be appreciated.
using System;
class Mainclass {
public static void sayHello(string username, string servername)
{
Console.WriteLine("Could you please enter your name : ");
username = Console.ReadLine();
Console.WriteLine("Hello " + username + "," + " my name is " + servername + ".");
Console.ReadLine();
}
public static float Arithmetic (float value)
{
return value * value;
}
static void Main()
{
Console.WriteLine("Hello, Welcome to the football scout app.");
sayHello((Console.ReadLine()), "Mr. Scout");
Arithmetic(200);
}
It certainly does run the method, you just have not implemented any output.
static void Main()
{
Console.WriteLine("Hello, Welcome to the football scout app.");
sayHello((Console.ReadLine()), "Mr. Scout");
Console.WriteLine("200 squared equals " + Arithmetic(200).ToString());
}
I have a problem with my class where it displays a comma before it displays the string and I cant find a way to take the comma out in the front and keep it in all the other places

}
else
{
return "error no money fool";
}
}
}
}
here is the main code if you need it

Console.Write("Enter your choice: ");
Console.ResetColor();
}
} while (input < 1 || input > 4);
Console.ResetColor();
return input;
}
}
}
here is my other class if you need that too but you probably don't
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Carnival
{
class GameBooth
{
//properties
public double Cost { get; set; }
public string FirstPrize { get; set; }
public string ConsolationPrize { get; set; }
public int w { get; set; }
public int l { get; set; }
//constructors
public GameBooth(double c, string fp, string cp)
{
Cost = c;
FirstPrize = fp;
ConsolationPrize = cp;
}
//methods
public string Start()
{
Random r = new Random();
w = 1;
l = 1;
for (int i = 1; i < 3; i++)
{
int randomChoice = r.Next(0, 400);
if ( randomChoice == 1)
{
w++;
}
}
if (w == 3)
{
return FirstPrize;
}
else
{
return ConsolationPrize;
}
}
}
}
Update the line to:
PrizesWon = string.IsNullOrEmpty(PrizesWon) ? newPrize : newPrize + "," + PrizesWon;
This uses the conditional operator to return a different result depending on whether or not PrizesWon already has something in it.
In your code you had put (,) before newPrize. For solving this, you have to just put it after PrizesWon variable and it will look like this :
**PrizesWon = newPrize + PrizesWon + ",";**
I hope your problem will be solved by this.
i am new at c# and i have a problem in this small program
i want to return the entered information in method ClientsDetails to use them in method Print().
Any help plz ?
public static void Main(string[] args)
{
ClientsDetails();
Print(???,???,???);
Console.ReadLine();
}
public static void ClientsDetails()
{
Console.Write("Client's first name: ");
string firstName = Console.ReadLine();
Console.Write("Client's last name: ");
string lastName = Console.ReadLine();
Console.Write("Client's birthdate: ");
string birthday = Console.ReadLine();
}
public static void Print(string first, string last, string birthday)
{
Console.WriteLine("Client : {0} {1} was born on: {2}", first, last, Birthday);
}
}
You could use a struct:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
struct Person{
public static FirstName;
public static LastName;
public static Birthday;
}
class Program
{
static void Main(string[] args)
{
Person person = ClientsDetails();
Print(person.FirstName, person.LastName, person.Birthday);
Console.ReadKey();
}
public static Person ClientsDetails()
{
Person returnValue = new Person();
Console.Write("Client's first name: ");
returnValue.FirstName = Console.ReadLine();
Console.Write("Client's last name: ");
returnValue.LastName = Console.ReadLine();
Console.Write("Client's birthdate: ");
returnValue.Birthday = Console.ReadLine();
return returnValue;
}
public static void Print(string first, string last, string birthday)
{
Console.WriteLine(String.Format("Client : {0} {1} was born on: {2}", first, last, birthday));
}
}
}
Or an array:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string person = ClientsDetails();
Print(person[0], person[1], person[2]);
Console.ReadKey();
}
public static string[] ClientsDetails()
{
string[] returnValue = new string[3];
Console.Write("Client's first name: ");
returnValue[0] = Console.ReadLine();
Console.Write("Client's last name: ");
returnValue[1] = Console.ReadLine();
Console.Write("Client's birthdate: ");
returnValue[3] = Console.ReadLine();
return returnValue;
}
public static void Print(string first, string last, string birthday)
{
Console.WriteLine(String.Format("Client : {0} {1} was born on: {2}", first, last, birthday));
}
}
}
Or references (pass by reference):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string firstName, lastName, birthday;
ClientsDetails(ref firstName, ref lastName, ref birthday);
Print(firstName, lastName, birthday);
Console.ReadKey();
}
public static void ClientsDetails(ref string firstName, ref string lastName, ref string birthday)
{
Console.Write("Client's first name: ");
firstName = Console.ReadLine();
Console.Write("Client's last name: ");
lastName = Console.ReadLine();
Console.Write("Client's birthdate: ");
birthday = Console.ReadLine();
}
public static void Print(string first, string last, string birthday)
{
Console.WriteLine(String.Format("Client : {0} {1} was born on: {2}", first, last, birthday));
}
}
}
I just corrected your program as your requirement.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
class Program
{
private static String FirstName;
private static String LastName;
private static String Birthday;
static void Main(string[] args)
{
ClientsDetails();
Print(FirstName, LastName, Birthday);
Console.ReadKey();
}
public static void ClientsDetails()
{
Console.Write("Client's first name: ");
FirstName = Console.ReadLine();
Console.Write("Client's last name: ");
LastName = Console.ReadLine();
Console.Write("Client's birthdate: ");
Birthday = Console.ReadLine();
}
public static void Print(string first, string last, string birthday)
{
Console.WriteLine(String.Format("Client : {0} {1} was born on: {2}", first, last, Birthday));
}
}
}
There is a heap of way that you can pass the required arguments to your method, so for example simply you can do it like this:
String f = "first string";
String l = "last string";
String b = "birthday string";
Print(f,l,b);
BTW, in your case it seems that you want the user's inputs to be passed to the Print method, so a simple way is to just call the Print method inside your ClientsDetails method like this:
Print(firstName, lastName, birthday);
For a comprehensive resource about this, you can refer to the docs, as always. At the moment you can just neglect the Async Methods part.
Cant't figure out what I am doing wrong,want to display user name in console through a method in the same class,missing a minor syntax please have a look and guide me.
public class Program
{
string name;
public void GetName()
{
Console.WriteLine("Enter ur name");
name = Console.ReadLine();
Console.WriteLine("Name is",name);
Console.ReadLine();
}
static void Main()
{
Program p = new Program();
p.GetName();
Console.ReadLine();
}
}
You need to specify the format string try:
public class Program
{
string name;
public void GetName()
{
Console.WriteLine("Enter ur name");
name = Console.ReadLine();
Console.WriteLine("Name is {0}",name);
Console.ReadLine();
}
static void Main()
{
Program p = new Program();
p.GetName();
Console.ReadLine();
}
}
You can also do it like this
Console.Writeline("name is:" + name);
Console.WriteLine("Name is : " + name);
