Use split in C #

1. Separated by strings:
Using system. Text. regularexpressions;
String STR = "aaajsbbbjsccc ";
String [] sarray = RegEx. Split (STR, "JS", regexoptions. ignorecase );
Foreach (string I in sarray) response. Write (I. tostring () + "<br> ");
Output result:
Aaa
Bbb
CCC
2. Separate multiple characters:
String STR = "aaajbbbscccjdddseee"; string [] sarray = Str. Split (New char [2] {'J','s '});
Foreach (string I in sarray) response. Write (I. tostring () + "<br> ");
Output result:
Aaa
Bbb
CCC
Ddd
Eee
3. Separate them with a single character:
String STR = "aaajbbbjccc ";
String [] sarray = Str. Split ('J ');
Foreach (string I in sarray) response. Write (I. tostring () + "<br> ");
Output result:
Aaa
Bbb
CCC

//////////////////////////////////////// /// // String [] arr = Str. split ("O ");

This is a statement with syntax errors. The split separator parameter should be char [] or string [], and should not be a string. Correct example:

String STR = "technology ";
Char [] separator = {'O '};
String [] arr = Str. split (separator ); //////////////////////////////////////// //// // string. the split method has six overload functions:

Program code 1) Public String [] Split (Params char [] separator) 2) Public String [] Split (char [] separator, int count)
3) Public String [] Split (char [] separator, stringsplitoptions options)
4) Public String [] Split (string [] separator, stringsplitoptions options)
5) Public String [] Split (char [] separator, int count, stringsplitoptions options)
6) Public String [] Split (string [] separator, int count, stringsplitoptions options) Below we use some instances to explain how to use (the following string words = "1, 2.3 ,, 4 ";):
1. Public String [] Split (Params char [] separator)Program code string [] split = words. split (New char [] {','}); // return value: {"1", "2.3", "", "4 "}
String [] split = words. split (New char [] {',', '. '}); // return: {"1", "2", "3", "", "4 "}
2. Public String [] Split (char [] separator, int count)Itpub personal space, N: H! C0m/s3u \ u0002p program code string [] split = words. split (New char [] {',', '. '}, 2); // return: {"1", "2.3, 4 "}
String [] split = words. split (New char [] {',', '. '}, 6); // return: {"1", "2", "3", "", "4 "}
3. Public String [] Split (char [] separator, stringsplitoptions options)Program code string [] split = words. split (New char [] {',', '. '}, stringsplitoptions. removeemptyentries); // return value: {"1", "2", "3", "4"} empty element not retained
String [] split = words. split (New char [] {',', '. '}, stringsplitoptions. none); // return: {"1", "2", "3", "", "4"} retain null Elements
4. Public String [] Split (string [] separator, stringsplitoptions options)Program code string [] split = words. split (New String [] {",", ". "}, stringsplitoptions. removeemptyentries); // return value: {"1", "2", "3", "4"} empty element not retained

5. Public String [] Split (char [] separator, int count, stringsplitoptions options)Program code string [] split = words. split (New char [] {',', '.

String [] split = words. split (New char [] {',', '. '}, 6, stringsplitoptions. none); // return: {"1", "2", "3", "", "4"} retain null Elements
6. Public String [] Split (string [] separator, int count, stringsplitoptions options)Program code string [] split = words. split (New String [] {",", ". "}, 2, stringsplitoptions. removeemptyentries); // return value: {"1", "2.3, 4"} empty elements are not retained.
String [] split = words. split (New String [] {",", ". "}, 6, stringsplitoptions. none); // return: {"1", "2", "3 ","", "4"} to retain null elements, note that the Public String [] Split (string [] separator) function is not overloaded, so we cannot be like VB. net. split (","), but can only use words. split (',')
