C#: splitting a string and not returning empty string

Question

I have a string:

a = "1;2;3;" 

And I would like to split it this way:

foreach (string b in a.split(';')) 

How can I make sure that I return only 1, 2, 3 and not an 'empty string'?

If I split 1;2;3 then I will get what I want. But if I split 1;2;3; then I get an extra 'empty string'. I have taken suggestions and done this:

string[] batchstring = batch_idTextBox.Text.Split(';', StringSplitOptions.RemoveEmptyEntries); 

However, I am getting these errors:

Error 1 The best overloaded method match for 'string.Split(params char[])' has some invalid arguments C:\Documents and Settings\agordon\My Documents\Visual Studio 2008\Projects\lomdb\EnterData\DataEntry\DAL.cs 18 36 EnterData

Error 2 Argument '2': cannot convert from 'System.StringSplitOptions' to 'char' C:\Documents and Settings\agordon\My Documents\Visual Studio 2008\Projects\lomdb\EnterData\DataEntry\DAL.cs 18 68 EnterData

Answer 1

String.Split takes an array when including any StringSplitOptions:

string[] batchstring = batch_idTextBox.Text.Split(new [] { ';' }, StringSplitOptions.RemoveEmptyEntries); 

If you don't need options, the syntax becomes easier:

string[] batchstring = batch_idTextBox.Text.Split(';');
