Parameters
- buffer
- Type: array<System..::.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
- Type: System..::.Int32
The place in buffer at which to begin writing.
- count
- Type: System..::.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.
Return Value
Type:
System..::.Int32The 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.
This method returns after either count characters are read or the end of the file is reached. ReadBlock is a blocking version of this method.
