Method Read

Read()

Reads a single character from this reader and returns it with the two higher-order bytes set to 0. If possible, BufferedCharFilter returns a character from the buffer. If there are no characters available in the buffer, it fills the buffer and then returns a character. It returns -1 if there are no more characters in the source reader.

Declaration
public override int Read()
Returns
Type Description
System.Int32

The character read or -1 if the end of the source reader has been reached.
Overrides
System.IO.TextReader.Read()
Exceptions
Type Condition
System.IO.IOException

If this reader is disposed or some other I/O error occurs.

Read(Char[], Int32, Int32)

Reads at most length characters from this reader and stores them at offset in the character array buffer. Returns the number of characters actually read or -1 if the end of the source reader has been reached. If all the buffered characters have been used, a mark has not been set and the requested number of characters is larger than this readers buffer size, BufferedReader bypasses the buffer and simply places the results directly into buffer.

Declaration
public override int Read(char[] buffer, int offset, int length)
Parameters
Type Name Description
System.Char[] buffer

the character array to store the characters read.
System.Int32 offset

the initial position in buffer to store the bytes read from this reader.
System.Int32 length

the maximum number of characters to read, must be non-negative.
Returns
Type Description
System.Int32

number of characters read or -1 if the end of the source reader has been reached.
Overrides
System.IO.TextReader.Read(System.Char[], System.Int32, System.Int32)
Exceptions
Type Condition
System.ArgumentOutOfRangeException

if offset < 0 or length < 0, or if offset + length is greater than the size of buffer.
System.IO.IOException

if this reader is disposed or some other I/O error occurs.
