Question

Yep… it’s one of those days.

public string TagsInput { get; set; }

//further down
var tagList = TagsInput.Split(Resources.GlobalResources.TagSeparator.ToCharArray()).ToList();
tagList.ForEach(tag => tag.Trim()); //trim each list item for spaces
tagList.ForEach(tag => tag.Replace(" ", "_")); //replace remaining inner word spacings with _

Both ForEach loops don’t work. tagList is just a List.

Thank you!

Answer 1

Trim() and Replace() don’t modify the string they’re called on. They create a new string that has had the action applied to it.

You want to use Select, not ForEach.

tagList = tagList.Select(t => t.Trim()).Select(t => t.Replace(" ", "_")).ToList();
