What are pointers in C#?

A pointer is a variable whose value is the address of another variable, which is the direct address of a memory location.

The syntax for a pointer is -

type *var-name;

Here's how to declare a pointer type -

double *z; /* pointer to a double */

C# allows the use of pointer variables in functions or blocks of code marked by the unsafe modifier. Unsafe code or unmanaged code is a block of code that uses pointer variables.

The following is our module showing how to declare and use pointer variables. We have used the unsafe modifier here -

static unsafe void Main(string[] args) {
   int val = 50;
   int* x = &val;

   Console.WriteLine("Data: {0} ", val);
   Console.WriteLine("Address: {0}", (int)x);
   Console.ReadKey();
}
