Way too much code. Using arrays of characters, your switch constructs can be reduced to just a few lines of code, like so:
switch (c)
           case 'a': sb.Append("4"); break;
           case 'e': sb.Append("3"); break;
           case 'i': sb.Append("1"); break;
           case 'o': sb.Append("0"); break;
           case 'A': sb.Append("4"); break;
           case 'E': sb.Append("3"); break;
           case 'I': sb.Append("1"); break;
           case 'O': sb.Append("0"); break;
           default: sb.Append(c); break;
string rep="43104310";
int index= "aeioAEIO".IndexOf(c);
if (index<0) sb.Append(c);
else sb.Append(rep[index]);
where rep is used to further improve readability.

About the Author

Luc Pattyn
Software Developer (Senior) Perceler
Belgium Belgium
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.
