// 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
Remarks
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
