Parameters

buffer

When this method returns, this parameter contains the specified character array with the values between index and (index + count -1) replaced by the characters read from the current source.

index

The position in buffer at which to begin writing.

count

The maximum number of characters to read.

Returns

The number of characters that have been read. The number will be less than or equal to count, depending on whether all input characters have been read.

Exceptions

Type	Reason
ArgumentNullException	buffer is null.
ArgumentException	(index + count - 1) > buffer.Length.
ArgumentOutOfRangeException	index < 0 - or- count < 0.
System.IO.IOException	An I/O error occurred.

Remarks

The position of the underlying text reader is advanced by the number of characters that were read into buffer.

The method blocks until either count characters are read, or all characters have been read. This is a blocking version of TextReader.Read.
