C#:字符串拆分返回字符串列表和分隔符列表？

Question

在C#中是否有任何内置方式将文本拆分为单词和分隔符数组？我想要的是:

text = "word1 + word2 - word3";
string[] words = text.Split(new char[] { '+', '-'});
//Need list '+', '-' here?

有任何想法吗？显然我可以手工处理文本...... :)

使用Regex.split()捕获括号http://msdn.microsoft.com/en-us/library/byy2946e.aspx

string input = @"07/14/2007";   
string pattern = @"(-)|(/)";

foreach (string result in Regex.Split(input, pattern)) 
{
   Console.WriteLine("'{0}'", result);
}
// In .NET 1.0 and 1.1, the method returns an array of
// 3 elements, as follows:
//    '07'
//    '14'
//    '2007'
//
// In .NET 2.0, the method returns an array of
// 5 elements, as follows:
//    '07'
//    '/'
//    '14'
//    '/'
//    '2007'
