Do you need to dispose StreamReader?
Yes, StreamReader , StreamWriter , BinaryReader and BinaryWriter all close/dispose their underlying streams when you call Dispose on them. They don’t dispose of the stream if the reader/writer is just garbage collected though – you should always dispose of the reader/writer, preferrably with a using statement.
Does Dispose call close?
To do it right, you just need to know that Dispose() calls Close() (a pretty intimate piece of implementation trivia). Further, in the Dispose(bool) cases, you need to ignore Dispose() and just write a Dispose(bool) implementation that makes sure to chain the base class method.
Should stream be disposed?
Stream. Close: This method calls Dispose, specifying true to release all resources. Personally, I would stick with the first option, since it contains less “noise”.
Does Streamwriter dispose stream?
It does not dispose the stream. It simply closes it.
Does StreamWriter need to be closed?
You must call Close to ensure that all data is correctly written out to the underlying stream. Following a call to Close, any operations on the StreamWriter might raise exceptions. If there is insufficient space on the disk, calling Close will raise an exception.
How do you close streams?
Streams have a BaseStream. close() method and implement AutoCloseable , but nearly all stream instances do not actually need to be closed after use. Generally, only streams whose source is an IO channel (such as those returned by Files.
How do I close a stream?
Should I dispose MemoryStream?
MemoryStream does not have any unmanaged resources to dispose, so you don’t technically have to dispose of it. The effect of not disposing a MemoryStream is roughly the same thing as dropping a reference to a byte[] — the GC will clean both up the same way.
What happens if you dont close StreamWriter?
If you don’t close it, you can’t guarantee that it’ll write out the last piece of data written to it. This is because it uses a buffer and the buffer is flushed when you close the stream. Second, it will lock the file as open preventing another process from using it.
Does StreamWriter dispose stream?
Why do we close streams?
Normally, when a person (a stream) is done with their work, they get up and leave (the programmer closes the stream), which allows the computer (file descriptor/OS resources) to be used by someone else.
When should you close a stream?
Generally, only streams whose source is an IO channel (such as those returned by Files. lines(Path, Charset)) will require closing. Most streams are backed by collections, arrays, or generating functions, which require no special resource management.
