<p>What is the difference between a <a href="http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.group.aspx" rel="nofollow noreferrer">Group</a> and a <a href="http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.match.aspx" rel="nofollow noreferrer">Match</a> in .NET's RegEx?</p>

A
Match
is an object that indicates a particular regular expression matched (a portion of) the target text. A
Group
indicates a portion of a match, if the original regular expression contained group markers (basically a pattern in parentheses). For example, with the following code:
```
```
string text = "One car red car blue car";
string pat = @"(\w+)\s+(car)";
Match m = r.Match(text);
```
```
```
m
```
would be match object that contains two groups - group 1, from
```
(\w+)
```
, and that captured "One", and group 2 (from
```
(car)
```
) that matched, well, "car".
