Count | Returns the number of groups in the collection. |
![]() |
IsReadOnly | Gets a value that indicates whether the collection is read-only. |
![]() |
IsSynchronized | Gets a value that indicates whether access to the GroupCollection is synchronized (thread-safe). |
![]() |
Item[ ( [ ( Int32] ) ] ) | Enables access to a member of the collection by integer index. |
![]() |
Item[ ( [ ( String] ) ] ) | Enables access to a member of the collection by string index. |

|---|---|---|
![]() |
CopyTo | Copies all the elements of the collection to the given array beginning at the given index. |
![]() |
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() |
GetEnumerator | Provides an enumerator that iterates through the collection. |
![]() |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() |
GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |

Remarks
The collection is immutable (read-only) and has no public constructor. A GroupCollection object is returned by the Match..::..Groups property.
The collection contains one or more System.Text.RegularExpressions..::..Group objects. If the match is successful, the first element in the collection contains the Group object that corresponds to the entire match. Each subsequent element represents a captured group, if the regular expression includes capturing groups. If the match is unsuccessful, the collection contains a single System.Text.RegularExpressions..::..Group object whose Success property is false and whose Value property equals String..::..Empty.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
