Reads the next character from the current stream and advances the current position of the stream in accordance with the Encoding used and the specific character being read from the stream.

Namespace:   System.IO
Assembly:  mscorlib (in mscorlib.dll)

abstract ReadChar : unit -> char
override ReadChar : unit -> char

Return Value

Type: System.Char

A character read from the current stream.

Exception Condition

The end of the stream is reached.


The stream is closed.


An I/O error occurs.


A surrogate character was read.

If the ReadChar method attempts to read a surrogate character in the stream an exception will be raised and the position in the stream will advance. The position is restored to the original location before ReadChar was called if the stream is seekable; however, if the stream is unseekable, the position will not be corrected. If surrogate characters can be expected in the stream, use the ReadChars method instead.

Because of data formatting conflicts, using this method with the following encodings is not recommended:

  • UTF-7

  • ISO-2022-JP
