Double constructor when reversing Unity game

Question

When reversing Unity dll, the decompiler (i.e. dnSpy) sometimes would create a class with 2 constructors, which are mostly identical apart from some specific field set / not set.

Here is an example:

public TurretShootOrder(IGalaxyTarget target, string sectionName, GalaxyWeaponDefinition galaxyWeaponDefinition, float startShootTime, Vector3 startRandomDispersion, float startImpactTime, float endShootTime, Vector3 endRandomDispersion, float endImpactTime, int shootCount, float missProportion, int flags = 0, int salvoId = 0, int salvoTotalShootCount = 0, int inSalvoFirstShootIndex = 0)
{


    this.target = target;
    this.sectionName = sectionName;

AND:

public TurretShootOrder(IGalaxyTarget target, IGalaxyModuleSection targetSection, GalaxyWeaponDefinition galaxyWeaponDefinition, float startShootTime, Vector3 startRandomDispersion, float startImpactTime, float endShootTime, Vector3 endRandomDispersion, float endImpactTime, int shootCount, float missProportion, int flags = 0, int salvoId = 0, int salvoTotalShootCount = 0, int inSalvoFirstShootIndex = 0)
{
    this.target = target;
    this.sectionName = string.Empty;

As you can see the second implementation doesn't set the sectionName on initialization. Otherwise these constructors are identical.

So, how do I combine these 2 constructors together?

Answer 1

Based on the discussion in comments and further investigation, when the class is instantiated like this:

 TurretShootOrder turretShootOrder2 = new TurretShootOrder(firstFakeTarget, null, ....

then it is neccessary to decide, which type the second parameter has in this case. Is it String or IGalaxyModuleSection?

In the above example according to C# rules it can't be a String. As then it won't be equal to null, but to "" (Empty.String). Which points to the type of that second parameter, which in this case is IGalaxyModuleSection.

Thus, there is a missing variable introduction in the code where the class got instantiated. So, the (simplified) solution could look like this:

 IGalaxyModuleSection targetSection = null;
     TurretShootOrder turretShootOrder2 = new TurretShootOrder(firstFakeTarget, targetSection, .
