Asp.net string segmentation function usage

Let's look at a simple example.

But its array length is 25, rather than 3. The following method replaces "[111cn.net]" with a special character, for example, $.

For example, if I want to split it according to [111cn.net],

The code is as follows:	Copy code
String [] arrstr2 = str. Replace ("[111cn.net]", "$"). Split ('$ ');

Check other methods.

, The simplest and most commonly used method. Open vs.net to create a console project by separating a specified character. Enter the following program in the Main () method.

The code is as follows:	Copy code
String s = "abcdeabcdeabcde "; String [] sArray = s. Split ('C '); Foreach (string I in sArray) Console. WriteLine (I. ToString ()); Output the following results: AB Deab Deab De

2. Use multiple characters for segmentation

The code is as follows:	Copy code
String s = "abcdeabcdeabcde" String [] sArray1 = s. Split (new char [3] {'C', 'D', 'E '}); Foreach (string I in sArray1) Console. WriteLine (I. ToString ()); Output the following results: AB AB AB

3. Use regular expressions

Add reference

The code is as follows:	Copy code
Using System. Text. RegularExpressions; String content = "agcsmallmacsmallgggsmallytx "; String [] resultString = Regex. Split (content, "small", RegexOptions. IgnoreCase) Foreach (string I in resultString) Console. WriteLine (I. ToString ());

Output the following results:
Agc
Mac
Ggg
Ytx

There is also an uncommon method

The code is as follows:

The code is as follows:	Copy code
String str = "reterry [111cn.net] is the webmaster of [111cn.net "; String [] arrstr = str. split (new char [] {'[','s ', 'O','s', 'u', 'O', '8 ','. ', 'C', 'O', 'M','] '}); For (int I = 0; I <arrstr. Length; I ++) { Response. Write (arrstr [I]); }
