1. public class RootClass
2. {
3. string PassValue;
4. public RootClass()
5. {
7. }
8. public RootClass(string PassAValue)
9. {
10. PassValue = PassAValue;
11. }
13. public void ShowValue()
14. {
15. Console.WriteLine(PassValue);
16. }
17. }
19. public class NextClass
20. {
21. public void PassValue()
22. {
23. RootClass root = new RootClass("PassAnyValueHere");
24. root.ShowValue();
25. }
26. }
This is the simple example where we use constructor to pass a value from one class to another.

There are multiple way to pass value from one class to another.

you can use constructor, property, Static methods.

If you need some sample code then I can provide that to you too.

Are you looking like this:

public class Employee
{
public string Name { get; set; }
}
public class MyClass
{
public Employee EmpObj;
public void SetObject(Employee obj)
{
EmpObj = obj;
}
}
public class Program
{
static void Main(string[] args)
{
Employee someTestObj = new Employee();
someTestObj.Name = "Manas";
MyClass cls = new MyClass();
cls.SetObject(someTestObj);
}
}

What I understood from your question.

The below sample program (Find missing letter from array) having Two classes.

The Class1 return value to Class Program (var getValue) and use it wherever you want.

Required using statements are as follows :

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

class Program
{
static void Main(string[] args)
{
var getValue= Class1.FindMissingLetter(new[] { 'a', 'b', 'c', 'd', 'f' });
Console.WriteLine("The missing letter is : {0} ",getValue);
Console.ReadLine();
}
}
public class Class1
{
public static char FindMissingLetter(char[] array)
{
List<int> myLst = new List<int>();
foreach (char c in array)
{
int f = (int)c;
myLst.Add(f);
}
var a= Enumerable.Range(97,122).Except(myLst).First();
char c1 = (char)a;
return c1;
}
}
