How to access array elements using a pointer in C#?
In C#, an array name and a pointer to a data type same as the array data, are not the same variable type. For example, int *p and int[] p, are not the same type. You can increment the pointer variable p because it is not fixed in memory but an array address is fixed in memory, and you can't increment that.
Here is an example −
Example
using System;
namespace UnsafeCodeApplication {
class TestPointer {
public unsafe static void Main() {
int[] list = {5, 25};
fixed(int *ptr = list)
/* let us have array address in pointer */
for ( int i = 0; i < 2; i++) {
Console.WriteLine("Address of list[{0}]={1}",i,(int)(ptr + i));
Console.WriteLine("Value of list[{0}]={1}", i, *(ptr + i));
}
Console.ReadKey();
}
}
}Output
Here is the output −
Address of list[0] = 31627168 Value of list[0] = 5 Address of list[1] = 31627172 Value of list[1] = 25
