How to convert string to list in C#

If you want to break the string into individual characters and store them in a list, you can use the ToList() method.

How to convert a string to a list of chars in C#?

List<char> charList = str.ToList();
// Output the list of characters
foreach (var c in charList)
    Console.WriteLine(c);

If you want to split the string into a list of substrings based on a delimiter, you can use the Split() method.

For example, Convert a string into a list of substrings in C#

// to string list c#
string str = "apple,banana,orange";
List<string> list = new List<string>(str.Split(','));

// Output the list of substrings
foreach (var item in list)
    Console.WriteLine(item);

Output:

apple
banana
orange

If you want to convert the example below to a List<string> delimited by commas, in one line

var names = "Brian,Joe,Chris";

You can write

List<string> result = names.Split(new char[] { ',' }).ToList();

or

List<string> result = names.Split(',').ToList();
