SocketAsyncEventArgs.SetBuffer Method (Byte[], Int32, Int32)

Sets the data buffer to use with an asynchronous socket method.

Namespace:  System.Net.Sockets
Assembly:  System.Net (in System.Net.dll)
public void SetBuffer(
	byte[] buffer,
	int offset,
	int count
)

Parameters

buffer
Type: System.Byte[]
The data buffer to use with an asynchronous socket method.
offset
Type: System.Int32
The offset, in bytes, in the data buffer where the operation starts.
count
Type: System.Int32
The maximum amount of data, in bytes, to send or receive in the buffer.
ExceptionCondition
ArgumentException

There are ambiguous buffers specified. This exception occurs if the Buffer property is also not null and the BufferList property is also not null.

ArgumentOutOfRangeException

An argument was out of range. This exception occurs if the offset parameter is less than zero or greater than the length of the array in the Buffer property. This exception also occurs if the count parameter is less than zero or greater than the length of the array in the Buffer property minus the offset parameter.

The offset and count parameters can't be negative numbers. The combination of the offset and count parameters must be in bounds of the data array in the buffer parameter.

This method sets the Buffer property to the buffer parameter, the Count property to the count parameter, and the Offset property to the offset parameter.
