Summary of several methods to split strings using split in C #

Method 1:

Copy codeThe Code is as follows: 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

Method 2:

We can see that the result is separated by a specified character. Use another constructor to separate multiple characters:

Copy codeThe Code is as follows: string s = abcdeabcdeabcde
String [] sArray1 = s. Split (new char [3] {c, d, e });
Foreach (string I in sArray1)
Console. WriteLine (I. ToString ());

You can output the following results:
AB
AB
AB

Method 3:

In addition to the above two methods, the third method is to use a regular expression. Create a console project. Then add using System. Text. RegularExpressions;

Copy codeThe Code is as follows: 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

Method 4:

Copy codeThe Code is as follows: string str1 = My *** is ********************** teacher;
String [] str2;
Str1 = str1.Replace (*****,*);
Str2 = str1.Split (*);
Foreach (string I in str2)
Console. WriteLine (I. ToString ());

Method 5:

Copy codeThe Code is as follows: string str1 = I'm;
The result I want to display is: I am a teacher.
If I use the fourth method above, the following error will occur: I am a teacher. There is a space in the middle of the output, so the output result is not the expected result, which returns to the regular expression, then you can use the fifth method below:
String str1 = I'm a ********************** teacher;
String [] str2 = System. Text. RegularExpressions. Regex. Split (str1, @ [*] + );
Foreach (string I in str2)
Console. WriteLine (I. ToString ());

Here, we use [*] + to skillfully accomplish our goal.
