Public ReadOnly Property Item ( _
    groupname As String _

public Group this[
    string groupname
] { get; }

Parameters

• groupname
  Type: System. . :: . .String
  The name of a capturing group.

Property Value

Type: System.Text.RegularExpressions. . :: . .Group
The member of the collection specified by groupname.

Remarks

groupName can be either the name of a capturing group that is defined by the (?<name>) element in a regular expression, or the string representation of the number of a capturing group that is defined by a grouping construct. For more information about groups in regular expressions, see Grouping Constructs.

If groupname is not the name of a capturing group in the collection, or if groupname is the name of a capturing group that has not been matched in the input string, the method returns a Group object whose Group..::..Success property is false and whose Group.Value property is String..::..Empty.

.NET Framework Security

• Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see dd66cd4c-b087-415f-9c3e-94e3a1835f74.
