FAQ for C++ to C# Converter
Q: Are the original C++ files altered in any way?
Your existing code is left completely intact. The new C# files are written to the new location that you specify.
Q: What is the conversion accuracy?
Our accuracy is the highest in the industry, but there will be significant adjustments required for all but the most trivial conversions. C++ code is much more complex than C# code, so there are no direct equivalents for many aspects of C++. Read the rest of the FAQ to get an idea of a few things that are not converted. C++ to C# Converter is intended to reduce the amount of work you'll have to do to convert code to C#, but it is just the first step. Code that is heavily dependent on pointer manipulation is better left in C++.
Q: What type of code can be converted?
C, C++, Managed C++ (VC++ 2003), and C++/CLI (VC++ 2005 and above). Conversion accuracy will be highest for C++/CLI code.
Q: What about MFC and ATL resources?
C++ to C# Converter does not convert MFC or ATL resources.
Q: What about STL Containers?
C++ to C# Converter converts most references to std::vector, std::list, std::queue, and std::stack. A few methods of these containers that have no equivalent are not converted.
Q: What are the most common adjustments necessary after conversion?
Most C/C++ library function calls are not converted. However, we do convert a subset of the C-based string, keyboard I/O, math, and utility function calls, and some of the C++ keyboard I/O methods, STL-based string class methods, and STL containers (vector, list, queue, and stack).
Some pointer and address manipulation may remain in the converted code.
Multiple inheritance is not converted since it is not available in C#.
C++ templates are converted to, but are only roughly equivalent to, C# generics. These will likely require further attention.
Bit-by-bit copying of objects via the assignment operator is not the default in C#. We attempt to detect these cases and convert the assignment to a call to either the copy constructor (if used in a variable initialization) or the converted assignment operator overload (which is converted to a 'CopyFrom' method) and also provide a 'Warning' comment.
C# does not allow embedded assembly instructions. These are marked with a comment.
Types cannot be declared within methods in C#. These are marked with a comment.
There is no equivalent to friend functions or friend classes in C#. These are marked with a comment.
Unions and bit fields have no elegant equivalent in C#. Unions are converted to structs and marked with a comment. Simple unions are converted using the StructLayout and FieldOffset attributes.
Many operators that can be overloaded in C++ cannot be overloaded in C#. These are marked with a comment.
