Do I need to close stream C#?
You do not have to specifically call the Close method. Instead, ensure that every Stream object is properly disposed. You can declare Stream objects within a using block (or Using block in Visual Basic) to ensure that the stream and all of its resources are disposed, or you can explicitly call the Dispose method.
How do I stop StreamReader?
Close with a break statement to exit out. Closing the reader causes the subsequent peek to error as it’s closed.
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.
What is stream reader in C#?
C# StreamReader is used to read characters to a stream in a specified encoding. StreamReader. Read method reads the next character or next set of characters from the input stream. StreamReader is inherited from TextReader that provides methods to read a character, block, line, or all content.
Does using call close C#?
using calls the Dispose method of IDisposable , which is what Close does, as well. @djacobson: Whether Close calls Dispose or vice-versa is an implementation detail. In the case of StreamWriter then it is indeed Close that calls Dispose , but in SqlDataReader , for example, the Dispose method calls Close .
Should I 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.
What is StreamReader and StreamWriter in C#?
The StreamReader and StreamWriter classes are used for reading from and writing data to text files. These classes inherit from the abstract base class Stream, which supports reading and writing bytes into a file stream.
What is a StreamReader?
A StreamReader is a TextReader which means it is a Stream wrapper. A TextReader will convert (or encode) Text data (string or char) to byte[] and write them down to the underlying Stream .

How do I dispose of a streamreader type?
Use StreamReader for reading lines of information from a standard text file. This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a try / catch block.
What is the syntax of streamreader class in C#?
The syntax of the StreamReader class in C# is as follows: Data is read from the files using Streams in C#. The stream is the extra layer between the application and the file. Data from the file can be read smoothly by making use of the stream.
What is the difference between stream and streamreader in Java?
StreamReader is designed for character input in a particular encoding, whereas the Stream class is designed for byte input and output. Use StreamReader for reading lines of information from a standard text file. This type implements the IDisposable interface.
