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 position in buffer at which to begin writing.
- count
Type: System. . :: . .Int32
The maximum number of characters to read. If the end of the reader is reached before the specified number of characters is read into the buffer, the method returns.
Return Value
Type: System. . :: . .Int32
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 reader. This method returns 0 (zero) if it is called when no more characters are left to read.
