Use System. stringsplitoptions to remove null items in the string to be split

Something very simple. I learned it today and wrote it down.

When we use a character to split a string into a string array, if there is an item in the string to be split, that is, "", it will also appear in the result array. If you do not want to include null items in the result array, you can use a new enumerated stringsplitoptions in. NET 2.0. DetailsCodeAs follows:

String S =   " 0, 1, 2, " ;
String [] Res = S. Split ( New   Char [] {','} , Stringsplitoptions. removeemptyentries );
Foreach ( String Str In Res)
{
Console. writeline (STR );
}
Console. writeline ( " Total: {0} " , Res. Length );
Console. Readline ();

The result is:
0
1
2
Total: 3

If you change stringsplitoptions. None or you do not have this parameter (the default value is none), the result is:
0
1
2

Total: 4
