One thing commonly seen in C and C++ code is use of the NOT operator to check whether a struct or class pointer is set to NULL. For instance:
class value = NULL;
if( !value )
printf( “value is null” );
In C# code this results in an error because the compiler has no idea what “NOT” means on a class. To be able to use this syntax in C# you have to override the ! operator, which is something I’ve never had occasion to do, AND that there are no easy-to-find code examples of. Luckily it’s just like overloading any operator in C#:
public static bool operator !( ClassType ct )
if( ct == null )
It works and it saves me the trouble of changing around 700 lines of code. We’re now down to 20,392 errors.
