Should StreamReader be disposed?
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.
Does dispose close stream?
So, reading the code it is clear that that you can call Close() & Dispose() on streams as often as you like and in any order.
Should Streamwriters be disposed?
If you plan to leave it open, then it’s a good idea to pass the flag set to ‘true’, but then dispose the stream writer itself, so it doesn’t keep a reference to the stream and potentially could dispose other resources (though it doesn’t look like there are any resources besides the stream).
Do I need to dispose MemoryStream?
You needn’t call either Close or Dispose . MemoryStream doesn’t hold any unmanaged resources, so the only resource to be reclaimed is memory. The memory will be reclaimed during garbage collection with the rest of the MemoryStream object when your code no longer references the MemoryStream .
What is difference between dispose and Finalize in C#?
The main difference between dispose() and finalize() is that the method dispose() has to be explicitly invoked by the user whereas, the method finalize() is invoked by the garbage collector, just before the object is destroyed.
Could you explain the difference between destructor dispose and Finalize method?
Destructor implicitly calls the Finalize method, they are technically the same. Dispose is available with objects that implement the IDisposable interface. The destructor implicitly calls Finalize on the base class of the object.
What happens if you don’t close a stream C#?
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 MemoryStream need to be disposed?
Do you need to dispose FileStream?
In the specific case of a FileStream , you don’t need to dispose it to close the file, you only need to use the Close method. You should however dispose of the FileStream object anyway, as it has a finalizer.
What happens if I don’t dispose MemoryStream?
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 is MemoryStream flush?
Flush meaning clears all buffers for a stream and causes any buffered data to be written to the underlying device.
When to use finalize vs Dispose?
Method dispose( ) is used to free unmanaged resources whenever it is invoked. Method finalize( ) is used to free unmanaged resources before the object is destroyed. The method dispose( ) is to be implemented whenever there is a close( ) method. The method finalize( ) is to be implemented for unmanaged resources.
What is the difference between Finalize () and Dispose () methods?
When to use finalize vs Dispose C#?
What is difference between Finalize and Dispose in C#?
Finalize is the backstop method, called by the garbage collector when it reclaims an object. Dispose is the “deterministic cleanup” method, called by applications to release valuable native resources (window handles, database connections, etc.)
Why is it important to close the files that you have accessed in your Streamreader and StreamWriter?
Why is it important to close files and streams?
When you gracefully close those files, those resources are set free. In Java if you don’t close the streams and files, Garbage collection identifies the open files which have lost the reference and hence will close them.
Why do we need dispose in C#?
In the context of C#, dispose is an object method invoked to execute code required for memory cleanup and release and reset unmanaged resources, such as file handles and database connections.
What objects should be disposed C#?
Things We Should Dispose
- file handles.
- database connections.
- network connections.
- sockets.
- mutexes.
- bitmaps.
- windows.
