How can I join an array of strings but first remove the elements of the array that are empty?

Question

I am using the following:

return string.Join(\"\\n\", parts);

Parts has 7 entries but two of them are the empty string \"\". How can I fi

Answer 1

An alternate way of doing this is by using StringSplitOptions.RemoveEmptyEntries:

e.g.

string yourString = "The|quick||brown|||fox|is|here";
char[] delimiter = new char[] { '|' };

string result = string.Join(",", yourString.Split(delimiter, StringSplitOptions.RemoveEmptyEntries));

This gives:

The,quick,brown,fox,is,here

@Stefan Steiger:

string yourString = "echo 'foo' | sed '/foo/d;'";

This gives:

echo 'foo' , sed '/foo/d;'

Which is as I would expect. See the dotnetfiddle of it.
