using System.Text.RegularExpressions;//引用命名空间
1、普通分割字符串方式
string str = "a,b,c"; string[] arr = str.Split(','); foreach (string s in arr) { Console.WriteLine(s); }
->输出结果:
a
b
c
2、利用字符串进行分割字符串方式
string str = "a字体b字体c字体d字体e"; string strTemp = "字体"; string[] arr = Regex.Split(str, strTemp, RegexOptions.IgnoreCase); foreach (string s in arr) { Console.WriteLine(s); }
->输出结果:
a
b
c
d
e
3、多个字符分割字符串方式
string str = "a,b,c@d$e"; char[] charTemp = {',', '@', '$'}; string[] arr = str.Split(charTemp); foreach (string s in arr) { Console.WriteLine(s); }
或
string str = "a,b,c@d$e"; string[] arr = str.Split(new char[] { ',', '@', '$' }); foreach (string s in arr) { Console.WriteLine(s); }
->输出结果:
a
b
c
d
e
4、分割字符串且去除空字符数组方式
string str = "a,,,b,c,d,e"; string[] arr = str.Split(','); foreach (string s in arr) { Console.WriteLine(s); }
->输出结果:
a
b
c
d
e
string str = "a,,,b,c,d,e"; string[] arr = str.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries); foreach (string s in arr) { Console.WriteLine(s); }
->输出结果:
a
b
c
d
e
5、分割字符串且不区用作分割字符串的字符的大小写方式
string str = "bacAdae"; string[] arr = Regex.Split(str, "a", RegexOptions.IgnoreCase); foreach (string s in arr) { Console.WriteLine(s); }
->输出结果:
b
c
d
e
