Answer 1

If you are using .NET 3.5+, you can use linq.

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();

Answer 2

You can use Linq if you are using .NET 3.5 or later:

  test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray(); 

If you cannot use Linq, you can do it like this:

 var temp = new List<string>(); foreach (var s in test) { if (!string.IsNullOrEmpty(s)) temp.Add(s); } test = temp.ToArray(); 

Answer 3

I am writing the code below to remove an empty value in an array string.

 string[] test={"1","","2","","3"}; test= test.Except(new List<string> { string.Empty }).ToArray(); 

Answer 4

I prefer to use two parameters: spaces and an empty field:

 test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray(); test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();
