Pointer in Unsafe

Declaring a pointer

int* p1, p2, p3; // Ok
int *p1, *p2, *p3; // Invalid in C#

Example	Description (This table is from msdn2 )
`int* p`	p is a pointer to an integer
`int** p`	p is a pointer to pointer to an integer
`int*[] p`	p is a single-dimensional array of pointers to integers
`char* p`	p is a pointer to a char
`void* p`	p is a pointer to an unknown type

Operator/Statement	Use
*	to perform pointer indirection.
->	to access a member of a struct through a pointer.
[]	to index a pointer.
`&`	to obtain the address of a variable.
++ and --	to increment and decrement pointers.
+ and -	to perform pointer arithmetic.
==, !=, <, >, <=, and >=	to compare pointers.
stackalloc	to allocate memory on the stack.
fixed statement	to temporarily fix a variable in order that its address may be found.

Example

using System;
using System.Collections.Generic;
//csc unsafe/ unsafe_pointer.cs
namespace Test_This
{
class MainClass
{
public static void Main(string[] args)
{
Console.WriteLine("Hello World!");
//Process pp = new Process();
Process.method_1();
}
}
class Process
{
unsafe public static void method_1()
{
int count = 99;
int* p; // create an int pointer
p = &count; // put address of count into p
Console.WriteLine("Initial value of count is " + *p);
*p = 10; // assign 10 to count via p
Console.WriteLine("New value of count is " + *p);
}
}
