Validating dates in dd-MMM-yyyy format

DateTime dt1;
DateTime dt2;
if (DateTime.TryParseExact(str1, "dd-MMM-yyyy", null, DateTimeStyles.None, out dt1) &&
    DateTime.TryParseExact(str2, "dd-MMM-yyyy", null, DateTimeStyles.None, out dt2)) {
	// do something with those datetimes
}

I am an engineer with a background in electronics, software and mathematics.
 
I develop technical software, both for embedded systems and for desktop equipment. This includes operating systems, communication software, local networks, image processing, machine control, automation, etc.
 
I have been using all kinds of microcontrollers and microprocessors (Intel 4004/8080/8051/80386/Pentium, Motorola 680x/680x0/ColdFire/PowerPC, Microchip PIC, Altera NIOS, and many more), lots of programming languages (all relevant assemblers, Fortran, Basic, C, Java, C#, and many more), and different operating systems (both proprietary and commercial).
 
For desktop applications and general development tools I have been using both UNIX systems and Mac/MacOS for many years, but I have switched to x86-based PCs with Windows, Visual Studio and the .NET Framework several years ago.
 
I specialize in:
- cross-platform development (making software that runs on diverse hardware/OS combinations)
- instruction set simulation
- improving software performance, i.e. making sure the software runs the job at hand in as short a time as possible on the given hardware. This entails algorithm selection, implementation design, accurate measurements, code optimisation, and sometimes implementing virtual machines, applying SIMD technology (such as MMX/SSE), and more.
