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

Overloads

SortedSet<T>()

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

SortedSet<T>(IComparer<T>)

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

SortedSet<T>(IEnumerable<T>)

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

SortedSet<T>(IEnumerable<T>, IComparer<T>)

SortedSet<T>(SerializationInfo, StreamingContext)
Obsolete.

Remarks

This constructor is an O(1) operation.

SortedSet<T>()

Source:
SortedSet.cs

public:
 SortedSet();
public SortedSet ();
Public Sub New ()

Applies to

SortedSet<T>(IComparer<T>)

Source:
SortedSet.cs
Source:
SortedSet.cs
Source:
SortedSet.cs

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

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

Parameters

comparer
IComparer<T>

The default comparer to use for comparing objects.

Exceptions

comparer is null.

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.
var mediaFiles1 = new SortedSet<string>(new ByFileExtension());
' Create a sorted set using the ByFileExtension comparer.
Dim mediaFiles1 As 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

Applies to

SortedSet<T>(IEnumerable<T>)

Source:
SortedSet.cs
Source:
SortedSet.cs
Source:
SortedSet.cs

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

collection
IEnumerable<T>

The enumerable collection to be copied.

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.

Applies to

SortedSet<T>(IEnumerable<T>, IComparer<T>)

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

Caution

This API supports obsolete formatter-based serialization. It should not be called or extended by application code.

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);
[System.Obsolete("This API supports obsolete formatter-based serialization. It should not be called or extended by application code.", DiagnosticId="SYSLIB0051", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
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>
[<System.Obsolete("This API supports obsolete formatter-based serialization. It should not be called or extended by application code.", DiagnosticId="SYSLIB0051", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
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

info
SerializationInfo

The object that contains the information that is required to serialize the SortedSet<T> object.

context
StreamingContext

The structure that contains the source and destination of the serialized stream associated with the SortedSet<T> object.

Attributes

Remarks

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