Why does Console.Readline() have a limit on the length of text it allows? [duplicate]

Answer 1

A quick look at implementation with .NET Reflector gives this:

public static Stream OpenStandardInput()
{
    return OpenStandardInput(0x100);
}

public static Stream OpenStandardInput(int bufferSize)
{
  ...
}

256 is the default value of OpenStandardInput, so I guess it's by design. Note this is only for .NET as the Windows API does not have this limit.
