Summary of .NET properties:

.NET property	Description
BodyLength	Get the length of the body of the message in bytes when the body of the message is read-only.

BodyLength - Get Body Length

Interface:

Int64 BodyLength    
    {
      get;

ReadBoolean - Read Boolean Value

Interface:

Boolean ReadBoolean();

Read a boolean value from the bytes message stream.

Parameters:

None

Returns:

The boolean value that is read.

Exceptions:

XMSException
MessageNotReadableException
MessageEOFException

ReadSignedByte - Read Byte

Interface:

Int16   ReadSignedByte();

Read the next byte from the bytes message stream as a signed 8-bit integer.

Parameters:

None

Returns:

The byte that is read.

Exceptions:

XMSException
MessageNotReadableException
MessageEOFException

ReadBytes - Read Bytes

Interface:

Int32   ReadBytes(Byte[] array);                
Int32   ReadBytes(Byte[] array, Int32 length);

Read an array of bytes from the bytes message stream starting from the current position of the cursor.

Parameters:

array (output): The buffer to contain the array of bytes that is read. If the number of bytes remaining to be read from the stream before the call is greater than or equal to the length of the buffer, the buffer is filled. Otherwise, the buffer is partially filled with all the remaining bytes.
If you specify a null pointer on input, the method skips over the bytes without reading them. If the number of bytes remaining to be read from the stream before the call is greater than or equal to the length of the buffer, the number of bytes skipped is equal to the length of the buffer. Otherwise, all the remaining bytes are skipped. The cursor remains at the next position to read in the byte message stream.
length (input): The length of the buffer in bytes

Returns:

The number of bytes that are read into the buffer. If the buffer is partially filled, the value is less than the length of the buffer, indicating that there are no more bytes remaining to be read. If there are no bytes remaining to be read from the stream before the call, the value is XMSC_END_OF_STREAM.

If you specify a null pointer on input, the method returns no value.

Exceptions:

XMSException
MessageNotReadableException
