<para>The collection is immutable (read-only) and has no public constructor. The <see cref="M:System.Text.RegularExpressions.Regex.Matches(System.String,System.String)" /> method returns a <see cref="T:System.Text.RegularExpressions.MatchCollection" /> object.</para>
<para>The collection contains zero or more <see cref="T:System.Text.RegularExpressions.Match" /> objects. If the match is successful, the collection is populated with one <see cref="T:System.Text.RegularExpressions.Match" /> object for each match found in the input string. If the match is unsuccessful, the collection contains no <see cref="T:System.Text.RegularExpressions.Match" /> objects, and its <see cref="P:System.Text.RegularExpressions.MatchCollection.Count" /> property equals zero.</para>
<para>When applying a regular expression pattern to a particular input string, the regular expression engine uses either of two techniques to build the <see cref="T:System.Text.RegularExpressions.MatchCollection" /> object:</para>
<list type="bullet">
<item>
<para>Direct evaluation. </para>
<para>The <see cref="T:System.Text.RegularExpressions.MatchCollection" /> object is populated all at once, with all matches resulting from a particular call to the <see cref="M:System.Text.RegularExpressions.Regex.Matches(System.String)" /> method. This technique is used when the collection's <see cref="P:System.Text.RegularExpressions.MatchCollection.Count" /> property is accessed. It typically is the more expensive method of populating the collection and entails a greater performance hit.</para>
</item>
<item>
<para>Lazy evaluation. </para>
<para>The <see cref="T:System.Text.RegularExpressions.MatchCollection" /> object is populated as needed on a match-by-match basis. It is equivalent to the regular expression engine calling the <see cref="M:System.Text.RegularExpressions.Regex.Match(System.String)" /> method repeatedly and adding each match to the collection. This technique is used when the collection is accessed through its <see cref="M:System.Text.RegularExpressions.MatchCollection.GetEnumerator" /> method, or when it is accessed using the foreach statement (in C#) or the For Each...Next statement (in Visual Basic).</para>
</item>
</list>
<para>To iterate through the members of the collection, you should use the collection iteration construct provided by your language (such as foreach in C# and For Each…Next in Visual Basic) instead of retrieving the enumerator that is returned by the <see cref="M:System.Text.RegularExpressions.MatchCollection.GetEnumerator" /> method. </para>

<para>Accessing individual members of the <see cref="T:System.Text.RegularExpressions.MatchCollection" /> object by retrieving the value of the collection's <see cref="P:System.Text.RegularExpressions.MatchCollection.Count" /> property causes the regular expression engine to populate the collection using direct evaluation. ln contrast, calling the <see cref="M:System.Text.RegularExpressions.MatchCollection.GetEnumerator" /> method (or using the foreach statement in C# and the For Each...Next statement in Visual Basic) causes the regular expression engine to populate the collection on an as needed basis using lazy evaluation. Direct evaluation can be a much more expensive method of building the collection than lazy evaluation.</para>

<para>Instead of calling the <see cref="M:System.Text.RegularExpressions.MatchCollection.GetEnumerator" /> method to retrieve an enumerator that lets you iterate through the <see cref="T:System.Text.RegularExpressions.Match" /> objects in the collection, you should use the group iteration construct (such as foreach in C# and For Each…Next in Visual Basic) provided by your programming language.</para>
<para>Iterating the members of the <see cref="T:System.Text.RegularExpressions.MatchCollection" /> object using the <see cref="M:System.Text.RegularExpressions.MatchCollection.GetEnumerator" /> method (or the foreach statement in C# and the For Each...Next statement in Visual Basic) causes the regular expression engine to populate the collection on an as needed basis using lazy evaluation. This is analogous to repeatedly calling the <see cref="M:System.Text.RegularExpressions.Regex.Match(System.String)" /> method, and then adding the resulting match to the <see cref="T:System.Text.RegularExpressions.MatchCollection" /> object. In contrast, the regular expression engine uses direct evaluation to populate the collection all at once when the <see cref="P:System.Text.RegularExpressions.MatchCollection.Count" /> property is accessed. This can be a much more expensive method of building the collection than lazy evaluation. </para>
<para>Because the <see cref="T:System.Text.RegularExpressions.MatchCollection" /> object is generally populated by using lazy evaluation, trying to navigate to the next member of the collection may throw a <see cref="T:System.Text.RegularExpressions.RegexMatchTimeoutException" /> exception.
