Accessing a Member via Pointer (C# Programming Guide) 

To access a member of a pointer type, use the member access expression that takes the form:

expression -> identifier

Parameters

• expression
  A primary expression that evaluates to a pointer type, other than void*.

• ->
  The member access operator.

• identifier
  An accessible member of the type to which expression points.

Remarks

The member access operator -> is used to access fields or invoke methods of a struct through a pointer to the struct.

Example

In this example, a struct, CoOrds that contains the two coordinates x and y is declared and instantiated. By using the member access operator -> and a pointer to the instance home, x and y are assigned values.

// compile with: /unsafe

struct CoOrds
{
    public int x;
    public int y;
}

class AccessMembers
{
    static void Main() 
    {
        CoOrds home;

        unsafe 
        {
            CoOrds* p = &home;
            p->x = 25;
            p->y = 12;

            System.Console.WriteLine("The coordinates are: x={0}, y={1}", p->x, p->y );
        }
    }
}

Output

The coordinates are: x=25, y=12
