Overloads
| Read() |
Reads the next character from the input stream and advances the character position by one character. |
| Read(Char[], Int32, Int32) |
Reads a maximum of count characters from the current stream and writes the data to buffer, beginning at index. |
Read()
Reads the next character from the input stream and advances the character position by one character.
public:
override int Read();public override int Read ();override this.Read : unit -> intPublic Overrides Function Read () As IntegerReturns
The next character from the input stream, or -1 if no more characters are available. The default implementation returns -1.
Exceptions
An I/O error occurs.
The TextReader is closed.
Applies to
Read(Char[], Int32, Int32)
Reads a maximum of count characters from the current stream and writes the data to buffer, beginning at index.
public:
override int Read(cli::array <char> ^ buffer, int index, int count);public override int Read (char[] buffer, int index, int count);override this.Read : char[] * int * int -> intPublic Overrides Function Read (buffer As Char(), index As Integer, count As Integer) As IntegerParameters
- buffer
- Char[]
When this method returns, contains the specified character array with the values between index and (index + count - 1) replaced by the characters read from the current source.
- index
- Int32
The place in buffer at which to begin writing.
- count
- Int32
The maximum number of characters to read. If the end of the stream is reached before count of characters is read into buffer, the current method returns.
Returns
The number of characters that have been read. The number will be less than or equal to count, depending on whether the data is available within the stream. This method returns zero if called when no more characters are left to read.
Exceptions
An I/O error occurs.
index or count is negative.
The buffer length minus index is less than count.
buffer is null.
The TextReader is closed.
