Unity3d calling VC and CSharp DLLs

1.c# encapsulated DLLs

Now create a class in VS, just write a simple static class and static method can be, as follows:

namespace pnsd{    publicstaticclass  pn    {        public   Staticstring getName (string  name)        {            return  name;        }    }}

Then compile it into a DLL file named Pnsd.dll.

2. Using custom C # encapsulated DLL components in Unity  

Create a Plugins folder in unity, and all externally referenced DLL components must be placed under this file to be used

 using   Unityengine;  using   System.Collections;  using  pnsd; //  Not the name of the DLL file, but the name of the namespace  public  class   Test:monobehaviour { void   Start () { string  name = Pn.getname ( "PNSD  ); //  class name. Method Name  Debug.Log (name); //  output result   

3. First build a DLL project with VC

4. Then create a testunity.h file inside. The contents are as follows

extern " C " int // defining the Out -of-the-way interface

Save, OK, at the establishment of a testunity.cpp, the code is as follows:

#include "testunity.h" int testunity () {   return 0;//This is a function that can write any function you want to implement}

Then compile, build. The Testunity.dll file is generated.

Then put this file in your Unity project's assert plugins (if you don't have this file, you'll have to create it)

Then create a new C # script file Dlltest inside unity. The code is as follows

usingUnityengine;usingSystem.Collections;usingSystem.Runtime.InteropServices; Public classDlltest:monobehaviour
{[DllImport ("testunity")]    Private Static extern inttestunity (); //Use this for initialization    intI=testunity (); voidStart () {print (i); }    //Update is called once per frame    voidUpdate () {}}

Then drag the file into the camera inside unity and it's OK.

Then run, you can achieve the effect of ha.

If it is a C # encapsulated DLL, it is referenced by using, and if it is a C + + DLL, dllimport[". dll" to add a reference to the DLL
