I got a problem with a simple List in C#(not displaying the actually list)

List<int> MyList = new List<int>();
MyList.Add(1);
MyList.Add(2);
MyList.Add(3);
MyList.Add(4);
foreach(int item in MyList){
    System.Console.WriteLine(MyList);
}

This is what my code shows :

System.Collections.Generic.List`1[System.Int32]
System.Collections.Generic.List`1[System.Int32]
System.Collections.Generic.List`1[System.Int32]
System.Collections.Generic.List`1[System.Int32]

When you ToString an object (which is what Console.WriteLine does), and it hasn't overridden ToString() it writes the name of the class. However, you can just use item which looks like a simple mistake

var myList = new List<int> { 1, 2, 3, 4 };

foreach (var item in myList)
   System.Console.WriteLine(item);

// or, you can get fancy with string.Join

Console.WriteLine(string.Join(", ", myList));
