Remove blank values from array using C#

How can I remove blank values from an array?

For example:

string[] test={"1","","2","","3"};

in this case, is there any method available to remove blank values from the array using C#?

At the end, I want to get an array in this format:

test={"1","2","3"};

which means 2 values removed from the array and eventually I get 3.

If you are using .NET 3.5+ you could use LINQ (Language INtegrated Query).

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

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

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

If you can't use Linq then 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();

I write below code to remove the blank value in the array string.

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

I prefer to use two options, white spaces and empty:

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

This might have been old, but you could try

string[] test = new[] { "1", "", "2", "", "3" };
test = string.Join(",", test).Split(new string[] { "," }, Stringsplitoptions.Removeemptyentries);

Join the array and split again with the empty items removed.
