C# Класс CitiesSkylinesDetour.RedirectionHelper

Redirects all calls from method 'from' to method 'to'.

Primitive patching. Inserts a jump to 'target' at 'site'. Works even if both methods' callers have already been compiled.

Redirects all calls from method 'from' to method 'to'. This version works only if the 'from' method has already been compiled (use GetFunctionPointer to force this) but no function calling 'from' have already been compiled. In fact, this function forces compilation for 'to' and 'from'. 'to' and 'from' are assumed to be normal methods. After compilation, this method looks up the MonoJitInfo structs for both methods from domain->jit_info_hash and patches sets the pointer to native code to the code obtained from compiling 'to'.

Redirects calls on MSIL level. Note that this does not work over assembly boundaries, severly limiting the uses of this approach. The main problem is that IL uses tokens to identify methods. These tokens are bound to methods in the assembly metadata. In order to add calls to completely new methods (i.e. from external assemblies), one must thus edit the metadata. This method does not do this and only works for normal methods.
