- buffer Byte
- The buffer to read the data into.
- offset Int32
- The byte offset in buffer at which to begin writing data read from the stream.
- count Int32
- The maximum number of bytes to read.
- callback AsyncCallback
- An optional asynchronous callback, to be called when the read is complete.
- state Object
- A user-provided object that distinguishes this particular asynchronous read request from other requests.
IAsyncResultAn
IAsyncResult that represents the asynchronous read, which could still be pending.
| IOException | Attempted an asynchronous read past the end of the stream, or a disk error occurs. |
| ArgumentException | One or more of the arguments is invalid. |
| ObjectDisposedException | Methods were called after the stream was closed. |
| NotSupportedException | The current Stream implementation does not support the read operation. |
