c# - Best practice for Inline if statement in for loop -

I want to copy the list item to string code. If the listbox item has empty string, then ignore

why I can do this:

  foreach (string item in lstModelUsers.Items) {if (string.IsNullOrEmpty ( Items)) continue; other options. Default.model Removal User Add (item); }  

But this is not:

  foreach (string item is in lstModelUsers.Items) string.IsNullOrEmpty (item)? Continue: Options. Default.model Removal User Add (item);  

Although both appear to be the same, inline if statement generates a syntax error.
What is the best practice?

You can not use it to be the only expressions Accepts your code failing to compile because it can only be used as a statement , not an expression.

The best way to do this is to reject if expression is not required for you issue :

  Foreach (string item in lstModelUsers.Items) {if String.IsNullOrEmptE (item)) {Options.Default ModelRemoveUsers.Add (item); }}  

You can also use where :

  var itemsToAdd = lstModelUsers.Items .Cast & lt; String & gt; () Where (item => String.IsNullOrEmpty (item)); Foreign items (item items in string items) {Options. Default.modelUmUser Add (item); }  

If you are lucky, you may also find that there is an AddRange method in ModelRemoveUsers Not required at all:

Add for var items = lstModelUsers.Items .Cast & lt; String & gt; (). Where (item => String.IsNullOrEmpty (item)); Options.Default.ModelRemoveUsers.AddRange (itemsToAdd);
