StreamReader(System.IO.Stream stream) This constructor creates an object of the StreamReader based on the specified stream and using the default UTF-8 encoding. FileStream(System.IO.Stream stream, System.Text.Encoding encoding) The constructor created an object of the StreamReader class based on the specified Stream and character encoding.
The StreamReader class is a subclass of Codec and defines the following methods which every stream reader must define in order to be compatible to the Python codec registry. class StreamReader(stream(, errors)) Constructor for a StreamReader instance. All stream readers must provide this constructor interface. They are free to add additional keyword arguments, but only the ones defined here.
A stream reader is just that, a reader. You can copy the stream itself to a MemoryStream and use the handy .ToByteArray() which that class provides. If it already is a memory stream, well problem solved.StreamReader(Stream, Encoding) Initializes a new instance of the CrestronIO.StreamReader class for the specified stream, with the specified character encoding. StreamReader(String, Encoding, Boolean) Initializes a new instance of the CrestronIO.StreamReader class for the specified file name, with the specified character encoding and byte order mark detection option.Reads the stream from the current position to the end of the stream. Let's look at an example, where we write data to a file using StreamWriter and the read data from the file using StreamReader. To read from or write to a file, the File class provides 2 methods that return a StreamReader or a StreamWriter object respectively, in other words.
The basic issue is this: when using a StreamReader, and ReadLine, to process a text file,. I need to be able to REPOSITION the stream back to the starting record of the document, and extract until I reach the end of the document. Specifically, I need to note the byte-position of a particular record, so that I can BaseStream.Seek() back to it. I'm using a StreamReader because I am indeed.
StreamReader(Stream, Encoding, Boolean, Int32) Initializes a new instance of the CrestronIO.StreamReader class for the specified stream, with the specified character encoding, byte order mark detection option, and buffer size. Methods Name Description; Close: Closes the CrestronIO.TextReader and releases any system resources associated with the TextReader.
StreamReader.Peek method returns An integer representing the next character to be read, or -1 if there are no characters to be read or if the stream does not support seeking. Example. The following code example reads lines from a file until the end of the file is reached.
StreamReader: StreamReader is a helper class for reading characters from a Stream by converting bytes into characters using an encoded value. It can be used to read strings (characters) from different Streams like FileStream, MemoryStream, etc.
These interfaces are organised around the principle of an encoding with an associated stream (i.e. the reverse of arrangement in the io module), so the original PEP 100 design required that codec writers provide appropriate StreamReader and StreamWriter implementations in addition to the core codec encode() and decode() methods.
An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified charset. The charset that it uses may be specified by name or may be given explicitly, or the platform's default charset may be accepted. Each invocation of one of an InputStreamReader's read() methods may cause one or more bytes to be read from the.
The following code uses the StreamReader class to open, to read, and to close the text file. You can pass the path of a text file to the StreamReader constructor to open the file automatically. The ReadLine method reads each line of text, and increments the file pointer to the next line as it reads.
If you manipulate the position of the underlying stream after reading data into the buffer, the position of the underlying stream might not match the position of the internal buffer. To reset the internal buffer, call the DiscardBufferedData method; however, this method slows performance and should be called only when absolutely necessary.
StreamReader(Stream) Initializes a new instance of the StreamReader class for the specified stream. StreamReader(String) Initializes a new instance of the StreamReader class for the specified file name. StreamReader(Stream, Boolean) Initializes a new instance of the StreamReader class for the specified stream, with the specified byte order mark detection option.
The next set of characters, if any, in the current stream are read into the returned string. The character read is ended by line termination (carriage return and line feed) characters, or the stream end. The line termination characters are not themselves returned.

StreamReader(Stream, Encoding, Boolean, Int32, Boolean) Initializes a new instance of the StreamReader class for the specified stream based on the specified character encoding, byte order mark detection option, and buffer size, and optionally leaves the stream open. StreamReader(String).
