List<comma-separated strings> => List<string> in C#?

List<comma-separated strings> => List<string> in C#?

You can convert a List<string> where each element is a comma-separated string to a List<string> where each element is a separate string using LINQ's SelectMany() method and the string.Split() method.

Here's an example:

List<string> commaSeparatedList = new List<string> { "apple,banana,orange", "grape,kiwi", "pear" }; List<string> separateList = commaSeparatedList .SelectMany(s => s.Split(',')) .ToList();

The SelectMany() method flattens the resulting sequence of arrays into a single sequence of strings, and the ToList() method converts the sequence to a List<string>.

The resulting separateList will contain the following elements:

apple banana orange grape kiwi pear
