Net file streamreader

The path parameter is not required to be a file stored on disk; it can be any part of a system that supports access using streams. The detectEncodingFromByteOrderMarks parameter detects the encoding by looking at the first four bytes of the stream. See the Encoding. GetPreamble method for more information. The character encoding is set by the encoding parameter, and the buffer size is set to bytes.

The StreamReader object attempts to detect the encoding by looking at the first four bytes of the stream. Otherwise, the user-provided encoding is used. Otherwise, the UTF8Encoding is used. An object that specifies the configuration options for the underlying FileStream.

This constructor initializes the encoding as specified by the encoding parameter, and the internal buffer size to bytes. This constructor initializes the encoding as specified by the encoding parameter, the BaseStream property using the stream parameter, and the internal buffer size to bytes. The buffer size, in number of bit characters, is set by the bufferSize parameter.

If bufferSize is less than the minimum allowable size characters , the minimum allowable size is used. This constructor allows you to change the encoding the first time you read from the StreamReader object. When reading from a Stream , it is more efficient to use a buffer that is the same size as the internal buffer of the stream.

Unless you set the leaveOpen parameter to true , the StreamReader object calls Dispose on the provided Stream object when StreamReader.
