SortedSet<T> SortedSet<T> SortedSet<T> SortedSet<T> Constructors

Initializes a new instance of the SortedSet<T> class.

public:
 SortedSet();

public SortedSet ();

Public Sub New ()

Initializes a new instance of the SortedSet<T> class that uses a specified comparer.

public:
 SortedSet(System::Collections::Generic::IComparer<T> ^ comparer);

public SortedSet (System.Collections.Generic.IComparer<T> comparer);

new System.Collections.Generic.SortedSet<'T> : System.Collections.Generic.IComparer<'T> -> System.Collections.Generic.SortedSet<'T>

Public Sub New (comparer As IComparer(Of T))

Parameters

Exceptions

Examples

The following example defines a comparer (ByFileExtension) that is used to construct a sorted set that sorts file names by their extensions. This code example is part of a larger example provided for the SortedSet<T> class.

// Create a sorted set using the ByFileExtension comparer.
SortedSet<string> mediaFiles1 =
    new SortedSet<string>(new ByFileExtension());

' Create a sorted set using the ByFileExtension comparer.
Dim mediaFiles1 As SortedSet(Of String) = _
    New SortedSet(Of String)(New ByFileExtension)

// Defines a comparer to create a sorted set
// that is sorted by the file extensions.
public class ByFileExtension : IComparer<string>
{
    string xExt, yExt;

	CaseInsensitiveComparer caseiComp = new CaseInsensitiveComparer();

    public int Compare(string x, string y)
    {
        // Parse the extension from the file name. 
        xExt = x.Substring(x.LastIndexOf(".") + 1);
        yExt = y.Substring(y.LastIndexOf(".") + 1);

        // Compare the file extensions. 
        int vExt = caseiComp.Compare(xExt, yExt);
        if (vExt != 0)
        {
            return vExt;
        }
        else
        {
            // The extension is the same, 
            // so compare the filenames. 
            return caseiComp.Compare(x, y);
        }
    }
}

  ' Defines a comparer to create a sorted set
  ' that is sorted by the file extensions.
  Public Class ByFileExtension
      Implements IComparer(Of String)
      Dim xExt, yExt As String

      Dim caseiComp As CaseInsensitiveComparer = _
      					New CaseInsensitiveComparer
Public Function Compare(x As String, y As String) _
          As Integer Implements IComparer(Of String).Compare
 			' Parse the extension from the file name.
	xExt = x.Substring(x.LastIndexOf(".") + 1)
	yExt = y.Substring(y.LastIndexOf(".") + 1)

	' Compare the file extensions.
	Dim vExt As Integer = caseiComp.Compare(xExt, yExt)
	If vExt <> 0 Then
		Return vExt
	Else
		' The extension is the same, 
		' so compare the filenames. 
		Return caseiComp.Compare(x, y)
	End If
End Function        
      
  End Class

Remarks

If comparer does not implement IComparable<T>, you must specify an IComparer<T> object to be used.

Initializes a new instance of the SortedSet<T> class that contains elements copied from a specified enumerable collection.

public:
 SortedSet(System::Collections::Generic::IEnumerable<T> ^ collection);

public SortedSet (System.Collections.Generic.IEnumerable<T> collection);

new System.Collections.Generic.SortedSet<'T> : seq<'T> -> System.Collections.Generic.SortedSet<'T>

Public Sub New (collection As IEnumerable(Of T))

Parameters

Remarks

Duplicate elements in the enumerable collection are not copied into the new instance of the SortedSet<T> class, and no exceptions are thrown.

This constructor is an O(n log n) operation, where n is the number of elements in the collection parameter.

Initializes a new instance of the SortedSet<T> class that contains elements copied from a specified enumerable collection and that uses a specified comparer.

public:
 SortedSet(System::Collections::Generic::IEnumerable<T> ^ collection, System::Collections::Generic::IComparer<T> ^ comparer);

public SortedSet (System.Collections.Generic.IEnumerable<T> collection, System.Collections.Generic.IComparer<T> comparer);

new System.Collections.Generic.SortedSet<'T> : seq<'T> * System.Collections.Generic.IComparer<'T> -> System.Collections.Generic.SortedSet<'T>

Public Sub New (collection As IEnumerable(Of T), comparer As IComparer(Of T))

Parameters

Exceptions

Initializes a new instance of the SortedSet<T> class that contains serialized data.

protected:
 SortedSet(System::Runtime::Serialization::SerializationInfo ^ info, System::Runtime::Serialization::StreamingContext context);

protected SortedSet (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);

new System.Collections.Generic.SortedSet<'T> : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> System.Collections.Generic.SortedSet<'T>

Protected Sub New (info As SerializationInfo, context As StreamingContext)

Parameters

Remarks

This constructor is called during deserialization to reconstitute an object that is transmitted over a stream.
