A deadlock condition can result if the parent process calls p. WaitForExit before p. ReadToEnd and the child process writes enough text to fill the redirected stream.

The parent process would wait indefinitely for the child process to exit. The child process would wait indefinitely for the parent to read from the full StandardOutput stream. There is a similar issue when you read all text from both the standard output and standard error streams. The following C code, for example, performs a read operation on both streams. The code example avoids the deadlock condition by performing asynchronous read operations on the StandardOutput stream.

A deadlock condition results if the parent process calls p. ReadToEnd followed by p. ReadToEnd and the child process writes enough text to fill its error stream. The parent process would wait indefinitely for the child process to close its StandardOutput stream.

Process.WaitForExit and .Exited event aren’t working?.

The child process would wait indefinitely for the parent to read from the full StandardError stream. You can use asynchronous read operations to avoid these dependencies and their deadlock potential. Alternately, you can avoid the deadlock condition by creating two threads and reading the output of each stream on a separate thread.

You cannot mix asynchronous and synchronous read operations on a redirected stream. Once the redirected stream of a Process is opened in either asynchronous or synchronous mode, all further read operations on that stream must be in the same mode. However, you can read two different streams in different modes. The following example spawns a new user-defined executable and reads its standard output.

The output is then displayed in the console. Windows 8.
