BufferedStream.CanSeek Property

public:
 virtual property bool CanSeek { bool get(); };

public override bool CanSeek { get; }

member this.CanSeek : bool

Public Overrides ReadOnly Property CanSeek As Boolean

true if the stream supports seeking; false if the stream is closed or if the stream was constructed from an operating system handle such as a pipe or output to the console.

This code example is part of a larger example provided for the BufferedStream class.

// Check whether the underlying stream supports seeking.
Console::WriteLine( "NetworkStream {0} seeking.\n", bufStream->CanSeek ? (String^)"supports" : "does not support" );

// Check whether the underlying stream supports seeking.
Console.WriteLine("NetworkStream {0} seeking.\n",
    bufStream.CanSeek ? "supports" : "does not support");

// Check whether the underlying stream supports seeking.
printfn $"""NetworkStream {if bufStream.CanSeek then "supports" else "does not support"} seeking.\n"""

' Check whether the underlying stream supports seeking.
If bufStream.CanSeek Then
    Console.WriteLine("NetworkStream supports" & _
        "seeking." & vbCrLf)
Else
    Console.WriteLine("NetworkStream does not " & _
        "support seeking." & vbCrLf)
End If

If a class derived from Stream does not support seeking, calls to Length, SetLength, Position, and Seek throw a NotSupportedException.

If the stream is closed, this property returns false.
