CSharp C# Make a non-referenced copy of a string List

CSharp C# Make a non-referenced copy of a string List

Note: this will not work on class objects just primitives like string and int

Key section:

//Make a "copy" - not a reference - of the original list:       List<string> Copy_List = new List<string>(new List<string>(Original_List));

Output from example:

Show Original_List before changes: One Two Three Four Show Copy_List before changes: One Two Three Four Show Original_List after change to original list:  Note: 2nd ordinal value, "Two" will be gone from this list. One Three Four Show Copy_List after change to original list:  Note: 2nd ordinal value, "Two" will NOT be gone from this "copy" of the "original" list. One Two Three Four

Code:

void Main() { //First set up Original list of values: List<string> Original_List = new List<string>(); Original_List.Add("One"); Original_List.Add("Two"); Original_List.Add("Three"); Original_List.Add("Four"); //Make a "copy" - not a reference - of the original list:       List<string> Copy_List = new List<string>(new List<string>(Original_List)); //Show the values before the change: Console.WriteLine("Show Original_List before changes:"); Show_Values(Original_List); Console.WriteLine("Show Copy_List before changes:"); Show_Values(Copy_List); //Remove the 2nd string, ordinal 1, "Two", from the original but not the copy: Original_List.RemoveAt(1); //Show the values after the change: Console.WriteLine("Show Original_List after change to original list:"); Console.WriteLine("  Note: 2nd ordinal value, \"Two\" will be gone from this list."); Show_Values(Original_List); Console.WriteLine("Show Copy_List after change to original list:"); Console.WriteLine("  Note: 2nd ordinal value, \"Two\" will NOT be gone from this \"copy\" of the \"original\" list."); Show_Values(Copy_List); } public void Show_Values(List<string> ListNow) { foreach(string StringNow in ListNow) {       Console.WriteLine(StringNow); } }
