How to save data with a collision?

I want to know what I need to add to my script so when a collision happens with an object named cylinder happens then data in this case the name of the object (test1, TEST2,etc.) is saved.

I currently have
void OnCollisionEnter(Collision collision)
{
Debug.Log("I hit : " + collision.gameObject.name);
int rand = Random.Range(0, 10);

if (rand == 0)
{
SpawnObject(test1);
}
else if (rand == 1)
{
SpawnObject(TEST2);
}
else if (rand ==2)
{
SpawnObject(TEST3);
}
else if (rand == 3)
{
SpawnObject(TEST4);
}
else if (rand == 4)
{
SpawnObject(TEST5);
}
else if (rand == 5)
{
SpawnObject(TEST6);
}
else if (rand == 6)
{
SpawnObject(TEST7);
}
else if (rand == 7)
{
SpawnObject(TEST8);
}
else if (rand == 8)
{
SpawnObject(TEST9);
}
else if (rand == 9)
{
SpawnObject(TEST10);
}

}
void OnCollisionStay(Collision collision)
{
}
void OnCollisionExit(Collision collision)
{
}
}

Please use script tags. Also don't bump after 7 minutes.

 

Thanks for the help
