3.3 MatchCollection 类表示非重叠匹配的序列
该集合为只读的,并且没有公共构造函数。MatchCollection 的实例是由 Regex.Matches 属性返回的。使用 Regex 类的 Matches 方法,通过在输入字符串中找到的所有匹配填充 MatchCollection。下面代码示例演示了如何将集合复制到一个字符串数组(保留每一匹配)和一个整数数组(指示每一匹配的位置)中。
MatchCollection mc;
String[] results = new String[20];
int[] matchposition = new int[20];
Regex r = new Regex("abc"; //定义一个Regex对象实例
mc = r.Matches("123abc4abcd";
for (int i = 0; i < mc.Count; i++) //在输入字符串中找到所有匹配
{
results[i] = mc[i].Value; //将匹配的字符串添在字符串数组中
matchposition[i] = mc[i].Index; //记录匹配字符的位置
}
