Yes, we can create pointers. These are known as unsafe code.

We can apply these as :

unsafe
{
int* pi;
int intx = 1;
pi = &x;
System.Console.WriteLine("Value of intx is: " + *pi);
}

Yes it is in unsafe mode. You must set compiler option that you will work in unsafe mode. Then every method that will use pointers in it, it's signature must be declared with unsafe.
eg. public unsafe void MyPointerIterator(){

// Inside comes the pointer declaration
// eg. int i = 0;
// int* counter = &i;

}

Yes, pointers can be used in .net, but there is a limitation on its usage.
1. Pointers can be used in a code block/snippet which is marked as 'unsafe' - unsafe can be either modifier or a method
2. Pointers can be used for only value types and arrays, because GC can not have hold over pointers.

Usage -

public unsafe void DemoPointer()
{
int x = 10;
int *iPtr = &x;
Console.WriteLine((int)iPtr);
Console.WriteLine(*iPtr);
}
