For a description of the pointer indirection operator (*), see <hyperlink>25.5.1</hyperlink>. For a description of the member access operator (.), see <hyperlink>14.5.4</hyperlink>. </paragraph> <paragraph> <example>[Example: In the example <code_example><![CDATA[ struct Point { public int x; public int y; public override string ToString() { return "(" + x + "," + y + ")"; } } using System; class Test { static void Main() { Point point; unsafe { Point* p = &point; p->x = 10; p->y = 20; Console.WriteLine(p->ToString()); } } } ]]></code_example>the -> operator is used to access fields and invoke a method of a struct through a pointer. Because the operation P->I is precisely equivalent to (*P).I, the Main method could equally well have been written: <code_example><![CDATA[ using System; class Test { static void Main() { Point point; unsafe { Point* p = &point; (*p).x = 10; (*p).y = 20; Console.WriteLine((*p).ToString()); } } } ]]></code_example>end example]</example> </paragraph> </clause>
