What is a StreamReader?

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 .

What is StreamReader and StreamWriter in C#?

StreamReader and StreamWriter are found in the System.IO namespace. Both classes are useful when you want to read or write character-based data. This method is used to write data to a text stream without a newline. WriteLine() This method is used to write data to a text stream with a newline.

What does the following constructor do public StreamReader?

Remarks. This constructor initializes the encoding as specified by the encoding parameter, the BaseStream property using the stream parameter, and the internal buffer size to 1024 bytes. The StreamReader object calls Dispose() on the provided Stream object when StreamReader. Dispose is called.

How can I tell if StreamReader is open?

How to check if a StreamReader is still open?

  1. The StreamReader opens automatically in the Fichier class;
  2. The StreamReader opens when we use the overrided method ReadLine , and not before (we need to modify the file before reading it with a StreamReader ).

Is StreamReader thread safe?

The StreamWriter documentation has this to say: “Any public static (Shared in Visual Basic) members of this type are thread safe. StreamWriter extends the TextWriter class, which itself has a static method for generating a thread safe wrapper.

What is a StreamReader 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.

What is StreamReader C#?

What is the use of StreamReader?

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.

Is C# FileStream thread safe?

FileStream is not thread safe.

Is StringWriter thread safe C#?

The methods in this class can be called after the stream has been closed without generating an IOException. According to the JDK 7 documentation for StringWriter, it is backed by a StringBuffer, which is thread-safe. Since strings in C# are immutable, the StringBuilder class is used to build a string efficiently.

What kind of encoding is used in streamreader?

The StreamReader object attempts to detect the encoding by looking at the first four bytes of the stream. It automatically recognizes UTF-8, little-endian Unicode, big-endian Unicode, little-endian UTF-32, and big-endian UTF-32 text if the file starts with the appropriate byte order marks. Otherwise, the user-provided encoding is used.

How does streamreader convert byte stream to character stream?

Doing so, converts the byte stream to a character stream and allows us to read characters from it. This constructor creates an object of the StreamReader based on the specified stream and using the default UTF-8 encoding. The constructor created an object of the StreamReader class based on the specified Stream and character encoding.

What’s the difference between streamreader and stream class?

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. Important. This type implements the IDisposable interface.

What is the size of the streamreader constructor?

The following code example demonstrates this StreamReader constructor. This constructor initializes the encoding as specified by the encoding parameter, and the internal buffer size to 1024 bytes. The StreamReader object attempts to detect the encoding by looking at the first four bytes of the stream.
