示例1: Main
//引入命名空间
using System;
using System.Runtime.CompilerServices;
public struct Age {
public int years;
public int months;
}
public class FreeClass
{
public static Age FreeAge;
public static unsafe IntPtr AddressOfFreeAge()
{
fixed (Age* pointer = &FreeAge)
{ return (IntPtr) pointer; }
}
}
public class FixedClass
{
[FixedAddressValueType]
public static Age FixedAge;
public static unsafe IntPtr AddressOfFixedAge()
{
fixed (Age* pointer = &FixedAge)
{ return (IntPtr) pointer; }
}
}
public class Example
{
public static void Main()
{
AllocateMemory();
// Get addresses of static Age fields.
IntPtr freePtr1 = FreeClass.AddressOfFreeAge();
AllocateMemory();
IntPtr fixedPtr1 = FixedClass.AddressOfFixedAge();
AllocateMemory();
// Garbage collection.
GC.Collect();
GC.WaitForPendingFinalizers();
// Get addresses of static Age fields after garbage collection.
IntPtr freePtr2 = FreeClass.AddressOfFreeAge();
IntPtr fixedPtr2 = FixedClass.AddressOfFixedAge();
// Display addresses before and after garbage collection
Console.WriteLine("Normal static: {0} -> {1}", freePtr1, freePtr2);
Console.WriteLine("Pinned static: {0} -> {1}", fixedPtr1, fixedPtr2);
}
// Allocate memory for 100,000 objects.
static public void AllocateMemory()
{
for (int ctr = 0; ctr <= 100000; ctr++)
{
object o = new object();
}
}
}输出：
Normal static: 19932420 -> 19863704 Pinned static: 19985508 -> 19985508
