Split usage in C # ~

1. Delimited by string:

using System.Text.RegularExpressions; string str="aaajsbbbjsccc"; string [] Sarray=regex.split (str,"js", regexoptions.ignorecase); foreach (stringin"<br>");

Output Result:
Aaa
Bbb
Ccc

2, separated by 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 the characters with a single character:

string str="aaajbbbjccc"; string [] sarray=str. Split ('J'); foreach (stringin"<br>");

Output Result:
Aaa
Bbb
Ccc

////////////////////////////////////////////////string[] arr = str. Split ("O");

This is a syntax error statement, Split's separator parameter should be char[] or string[] and should not be a string. The correct example:

String str = "Technology";
Char[] Separator = {' O '};
string[] arr = str. Split (separator); The////////////////////////////////////////////////////String.Split method has 6 overloaded functions: Program code

1) Public string[] Split (params Char[] separator)2) Public string[] Split (Char[] Separator,intcount)3) Public string[] Split (Char[] separator, stringsplitoptions options)4) Public string[] Split (string[] separator, stringsplitoptions options)5) Public string[] Split (Char[] Separator,intcount, stringsplitoptions options)6) Public string[] Split (string[] Separator,intCount, stringsplitoptions options)

Below we have some examples to illustrate 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',' }); // return: {"1", "2.3", "" "," 4 "} string [] split = words. Split (new','. ' }); //

2. Public string[] Split (char[] separator, int count)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: {"1", "2", "3", "4"} do not preserve empty elements  string  [] split = words. Split (new  char[] { "   ", "  .   "}, Stringsplitoptions.none); //  return: {"1", "2", "3", "", "4"} Leave empty element  

4. Public string[] Split (string[] separator, stringsplitoptions options)Program code

string[] split = words. Split (New string[] {",","."}, Stringsplitoptions.removeemptyentries);//return: {"1", "2", "3", "4"} do not preserve empty elementsstring[] split = words. Split (New string[] {",","."}, Stringsplitoptions.none);//returned: {"1", "2", "3", "", "4"} Reserved Empty element

5. Public string[] Split (char[] separator, int count, stringsplitoptions options)Program code

string[] split = words. Split (NewChar[] {',','.'},2, stringsplitoptions.removeemptyentries);//returned: {"1", "2.3,,4"} does not preserve empty elementsstring[] split = words. Split (NewChar[] {',','.'},6, Stringsplitoptions.none);//returned: {"1", "2", "3", "", "4"} Reserved Empty element

6. Public string[] Split (string[] separator, int count, stringsplitoptions options)Program code

string[] split = words. Split (New string[] {",","."},2, stringsplitoptions.removeemptyentries);//returned: {"1", "2.3,,4"} does not preserve empty elementsstring[] split = words. Split (New string[] {",","."},6, Stringsplitoptions.none);//returned: {"1", "2", "3", "", "4"} Reserved Empty element

Note that there is no overloaded function public string[] Split (string[] separator), so we cannot use Words.split (",") like vb.net, and only use words. Split (', ')
