Here I will illustrate several common spli methods 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 , 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 , Separated by 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 a syntax error,The separator parameter of split should beChar[] Or string []. It should not be a string. Correct example:
