Writes a block of bytes to the file stream.
Assembly: mscorlib (in mscorlib.dll)
array is null.
offset and count describe an invalid range in array.
offset or count is negative.
An I/O error occurred.
- or -
Another thread may have caused an unexpected change in the position of the operating system's file handle.
The stream is closed.
The current stream instance does not support writing.
This method overrides Write.
The offset parameter gives the offset of the byte in array (the buffer index) at which to begin copying, and the count parameter gives the number of bytes that will be written to the stream. If the write operation is successful, the current position of the stream is advanced by the number of bytes written. If an exception occurs, the current position of the stream is unchanged.
Do not interrupt a thread that is performing a write operation. Although the application may appear to run successfully after the thread is unblocked, the interruption can decrease your application's performance and reliability.
