[Android.Runtime.Register("read", "()I", "GetReadHandler")]
public virtual int Read();[<Android.Runtime.Register("read", "()I", "GetReadHandler")>]
abstract member Read : unit -> int
override this.Read : unit -> intReturns
the next byte of data, or -1 if the end of the
file has been reached.
- Attributes
Exceptions
if this file is closed or another I/O error occurs.
Remarks
Reads a byte of data from this file. The byte is returned as an integer in the range 0 to 255 (0x00-0x0ff). This method blocks if no input is yet available.
Although RandomAccessFile is not a subclass of InputStream, this method behaves in exactly the same way as the InputStream#read() method of InputStream.

Reads up to b.length bytes of data from this file
into an array of bytes.
[Android.Runtime.Register("read", "([B)I", "GetRead_arrayBHandler")]
public virtual int Read(byte[]? b);[<Android.Runtime.Register("read", "([B)I", "GetRead_arrayBHandler")>]
abstract member Read : byte[] -> int
override this.Read : byte[] -> intParameters
- b
- Byte[]
the buffer into which the data is read.
Returns
the total number of bytes read into the buffer, or
-1 if there is no more data because the end of
this file has been reached.
- Attributes
Exceptions
if this file is closed or another I/O error occurs.
Remarks
Reads up to b.length bytes of data from this file into an array of bytes. This method blocks until at least one byte of input is available.
Although RandomAccessFile is not a subclass of InputStream, this method behaves in exactly the same way as the InputStream#read(byte[]) method of InputStream.

Reads up to len bytes of data from this file into an
array of bytes.

public virtual int Read(byte[]? b, int off, int len);[<Android.Runtime.Register("read", "([BII)I", "GetRead_arrayBIIHandler")>]
abstract member Read : byte[] * int * int -> int
override this.Read : byte[] * int * int -> intParameters
- b
- Byte[]
the buffer into which the data is read.
- off
- Int32
the start offset in array b
at which the data is written.
- len
- Int32
the maximum number of bytes read.
Returns
the total number of bytes read into the buffer, or
-1 if there is no more data because the end of
the file has been reached.
- Attributes
Exceptions
