Hello all: I'm new to coding and this forum, using c# visual studio 2012. I am trying to get this code to read the user input and read it on a separate line. I get an un-handled exception, not sure why. Thank You
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;


namespace Lesson_5_Project
{
    class EmpApp
    {
        static void Main()
        {
            
            char last;


            DisplayInstructions();
            last = GetName("Last:");


            DisplayName(last);            




            // Object: myEmployee
            Employee myEmployee = new Employee();


            // Instantiate the object
            myEmployee.GetPaySchedule();


            Console.ReadLine();
        }
        public static void DisplayInstructions()
        {
            Console.WriteLine("This program will calculate the employee's take-home pay.");
            /*Console.Write("Enter Last name: {0}", last);
            Console.ReadKey();*/
        }
        public static char GetName(string name1)
        {
            string inValue;
            char Name;


            Console.Write("Enter {0}", name1);
            inValue = Console.ReadLine();
            Name = char.Parse(inValue);/*An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll
                                           Additional information: String must be exactly one character long.*/


            return Name;
        }
        public static void DisplayName(char last)
        {
            Console.WriteLine("Last Name: {0}", last);


        }


    }
}

As message says char.Parse will accept only a single character string, and you are passing it a longer string. Should 'name' really be type char (one character)?

Thank You, I have updated the code to string, but now I can't get it to read the "employee name", I know I'm missing something somewhere, but not sure what. Here is my new code. Any help is very much appreciated.
namespace Lesson_5_Project
{
    class Employee
    {
        
        private string lname/*employeeName*/;
        private char inValue;
        private double payRate;
           
        public Employee()
                     
        {
        }
        /*public void GetEmployeeName()
        {
            EmployeeName();
            Console.WriteLine("Employee Name: {0}", lname);
                
            }
        }
            public void EmployeeName
        {
            
            get
            {
                return employeeName;
            }
            set
            {
                employeeName = inValue;
            }
}
            //employeeName = lname;

I have formatted your code for you. Please do it for us in future. Also, please post only relevant code. We shouldn't have to wade through a load of irrelevant stuff to locate the issue when you can omit all the irrelevant stuff and point us directly to the issue.
