c＃使用字符串而不是char作为分隔符来拆分字符串

Question

I have string string text = "1.2788923 is a decimal number. 1243818 is an integer. "; Is there a way to split it on the commas only ? This means to split on ". " but not on '.' . When I try string[] sentences = text.Split(". "); I get method has invalid arguments error..

Answer 1

Use String.Split Method (String[], StringSplitOptions) to split it like:

string[] sentences = text.Split(new string[] { ". " },StringSplitOptions.None);

You will end up with two items in your string:

1.2788923 is a decimal number
1243818 is an integer

Answer 2

你可以使用Regex.Split ：

string[] parts = Regex.Split(text, @"\. ");

Answer 3

The string(s) that you splitting on are expected to be in a separate array.

String[] s = new String[] { ". " };
String[] r = "1. 23425".Split(s, StringSplitOptions.None);

Answer 4

Use Regular Expressions

public static void textSplitter(String text)
   {

  string pattern = "\. ";           

String[] sentences = Regex.Split(text, pattern);

}
