SerialPort.BytesToRead Property

Gets the number of bytes of data in the receive buffer.

Namespace: System.IO.Ports
Assembly: Microsoft.SPOT.Hardware (in microsoft.spot.hardware.dll)

Syntax

public int BytesToRead { get; }

Property Value

The number of bytes of data in the receive buffer.

Remarks

The receive buffer includes the serial driver's receive buffer as well as internal buffering in the SerialPort object itself.

Note

The BytesToRead property can return a value larger than the ReadBufferSize property because the ReadBufferSize property represents only the Windows-created buffer while the BytesToRead property represents the SerialPort buffer in addition to the Windows-created buffer.

Version Information

Available in the .NET Micro Framework versions 3.0, 4.0, 4.1, and 4.2.
