Ok So I have to create a Date Class that will allow me to return the current day with data members of month , day, and year

this is what I have for from my Main() class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DateApp2
{
    class DateApp
    {
        static void Main();
        {   
            DateApp date1 = 
                 new DateApp (10, 31, 2011, "10/31/11");
            Console.Write (date1);
        }
        
        public static void DisplayResults(DateApp someDate)
        {
              Console.Clear();
              Console.WriteLine("Current Date: " + someDate.CalculateDate().ToString("F1");
                                
                                
        }   
            
       
        } // end of Main
    } // end of DateApp Class
} //end of namespace

and this is what I have from my "Date Class(helper/worker)" :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DateApp2
{
    class Date
    {
        private int monthDate;
        private int dayDate;
        private int yearDate;
        private string currentDate;
    } // end of Date Class

    public int MonthDate
    {
        get 
        {
            return monthDate;
        }
         set  
        {
            monthDate = value ; 
        }
    }

    public int DayDate 
    {
        get
        {
            return dayDate;
        }
            set 
        {
                dayDate = value;
        }
    }

    public int YearDate
    {
        get
        {
            return yearDate;
        }
            set
        {
                yearDate = value;
        }
     }
    
    public string CurrentDate
    {
        get 
        {
            return currentDate;
        } 
            set 
        {
                currentDate = value;
        }
    }

     //default constructor
    public Date()
    {

    }

    public Date(int month, int day, int year , string current)

    {
        monthDate = month;
        dayDate = day;
        yearDate = year;
        currentDate = current;
    } 

    public Date (int month , int day , int year)
    {
        monthDate = month;
        dayDate = day;
        yearDate= year;
    }

    public Date (string today)
    {
         currentDate = today;
    }

    public CalculateDate()
    {
       return int monthDate, int dayDate, int yearDate
    }

    public override string ToString()
    {
        return string.Format ("{0,20}", "Date App") +
                              "\n\nMonth: " + monthDate +
                              "\n\nDay: " + dayDate +
                              "\n\nYear: " + yearDate +
                              "\n\nCurrent Date: " + CalculateDate().ToString("F1");
    }
   
} // end namespace

For Error6:

DateApp date1 = new DateApp (10, 31, 2011, "10/31/11");

You have used this to create object for class DateApp,and passed four arguments, but you don't have a constructor for the class DateApp.

For Error 7 and 8:

Console.Write (date1);

You can't print an object, rather you can print string,int.

And there are many syntax errors, try to find it

UPDATE************* Ok I figured out view issues I reduced the errors down to 10. But now Im really royally stuck :(

here is the helper/worker class "Date":

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DateApp2
{
    class Date
    {
        private int monthDate;
        private int dayDate;
        private int yearDate;
        private string currentDate;
     // end of Date Class

    public int MonthDate
    {
        get 
        {
            return monthDate;
        }
         set  
        {
            monthDate = value ; 
        }
    }

    public int DayDate 
    {
        get
        {
            return dayDate;
        }
            set 
        {
                dayDate = value;
        }
    }

    public int YearDate
    {
        get
        {
            return yearDate;
        }
            set
        {
                yearDate = value;
        }
     }
    
    public string CurrentDate
    {
        get 
        {
            return currentDate;
        } 
            set 
        {
                currentDate = value;
        }
    }

     //default constructor
    public Date()
    {

    }

    public Date(int month, int day, int year , string current)

    {
        monthDate = month;
        dayDate = day;
        yearDate = year;
        currentDate = current;
    } 

    public Date (int month , int day , int year)
    {
        monthDate = month;
        dayDate = day;
        yearDate= year;
    }

    public Date (string today)
    {
         currentDate = today;
    }

    public string CalculateDate()
    {
        return currentDate;
    }

    public override string ToString()
    {
        return string.Format ("{0,20}", "Date App") +
                              "\n\nMonth: " + monthDate +
                              "\n\nDay: " + dayDate +
                              "\n\nYear: " + yearDate +
                              "\n\nCurrent Date: " + currentDate.ToString("F1");
    } //end of ToString method
   
    } // end of class "Date"
} //end of namespace

and here is the Main() class DateApp:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DateApp2
{
    class DateApp
    {
        static void Main();
        {   
            DateApp date1 = 
                 new DateApp (10, 31, 2011, "10/31/11");
            Console.Write (date1);
        } //end of main
        
        public static void DisplayResults(DateApp someDate)
        {
              Console.Clear();
              Console.WriteLine("Current Date: " + someDate.CalculateDate().ToString("F1");
                                
                                
        }   //end of DisplayResults
            
       
        } // end of class DateApp
 } // end of Namespace

The main.

namespace DateApp2

    class Program

        static void Main(string[] args)
        {
            ClsDate objDate = new ClsDate(10, 31, 2011, "10/31/11");
            objDate.showDate();

            //Console.WriteLine(objDate.ToString());
            Console.Read();

    }//Fin cls.
