Split string in c#, empty space also considered as string how to discard empty string

I have a text box where I enter the input as 

"Two; [email protected];"

string[] result = txt_to.Text.Split(';');

so what happens here is the result takes three strings. 1. two 2. [email protected] 3. "" (empty space) since there is a ; after the email it considers that as a string how can I discard the 3rd string that it takes. It happens when I enter the email and a semicolon and press the space bar it throws a error. If it is just space after the semicolon the split should discard it how to do that

string s=txt_to.Text;
s = s.Replace(" ", "");
string[] result = s.Split(';');

It looks to me like it would make sense to discard empty strings from the result anyway, not only at the end. If this is the case, you could use

char[] separators = new char[]{';'};
string[] result = txt_to.Text.Split(separators , StringSplitOptions.RemoveEmptyEntries);

I'm gathering you want to split the string into a number of strings, but exclude any "empty" strings (those consisting only of whitespace)? This ought to help you out...

string[] result = txt_to.Text.Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);

Call the same method, adding StringSplitOptions.RemoveEmptyEntries

Pass StringSplitOptions parameter

var result = yourString.Split(new string[] {";"}, StringSplitOptions.RemoveEmptyEntries);
