全面剖析C#正则表达式

Match方法是在输入字符串中搜索正则表达式的匹配项，并Regex 类的 Match 方法返回 Match 对象，Match 类表示正则表达式匹配操作的结果。下面的例子演示Match方法的使用，并利用Match对象的Group属性返回Group对象：

string text = @"public string testMatchObj string s string match ";

string pat = @"(\w+)\s+(string)";

// Compile the regular expression.

Regex r = new Regex(pat, RegexOptions.IgnoreCase);

// Match the regular expression pattern against a text string.

Match m = r.Match(text);

int matchCount = 0;

while (m.Success)

{

Response.Write("Match"+ (++matchCount) + "<br>");

for (int i = 1; i <= 2; i++)

{

Group g = m.Groups[i];

Response.Write("Group"+i+"='" + g + "'" + "<br>");

CaptureCollection cc = g.Captures;

for (int j = 0; j < cc.Count; j++)

{
