如何使用C#将字符串拆分一次

Question

示例:a - b - c必须拆分为a和b - c,而不是3个子串

Answer 1

指定所需的最大项目数:

string[] splitted = text.Split(new string[]{" - "}, 2, StringSplitOptions.None);

Answer 2

string s = "a - b - c";
string[] parts = s.Split(new char[] { '-' }, 2);
// note, you'll still need to trim off any whitespace

Answer 3

"a-b-c".Split( new char[] { '-' }, 2 );
