BufferedStream.CanSeek Property

Gets a value indicating whether the current stream supports seeking.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Overrides ReadOnly Property CanSeek As Boolean

Property Value

Type: System.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.

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.

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

' 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
