If you are using .NET 3.5+ you could use linq.
如果您使用 .NET 3.5+，则可以使用 linq。
test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();

You can use Linq in case you are using .NET 3.5 or later:
如果您使用的是 .NET 3.5 或更高版本，则可以使用 Linq：
test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
If you can't use Linq then you can do it like this:
如果你不能使用 Linq，那么你可以这样做：
var temp = new List<string>();
foreach (var s in test)
{
if (!string.IsNullOrEmpty(s))
temp.Add(s);
}
test = temp.ToArray();

I prefer to use two options, white spaces and empty:
我更喜欢使用两个选项，空格和空：
test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();

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