示例1: Main
//引入命名空间
using System;
using System.Runtime.CompilerServices;
public class Example
{
public static void Main()
{
var mc1 = new ManagedClass();
var mc2 = new ManagedClass();
var mc3 = new ManagedClass();
var cwt = new ConditionalWeakTable<ManagedClass, ClassData>();
cwt.Add(mc1, new ClassData());
cwt.Add(mc2, new ClassData());
cwt.Add(mc3, new ClassData());
var wr2 = new WeakReference(mc2);
mc2 = null;
GC.Collect();
ClassData data = null;
if (wr2.Target == null)
Console.WriteLine("No strong reference to mc2 exists.");
else if (cwt.TryGetValue(wr2.Target, out data))
Console.WriteLine("Data created at {0}", data.CreationTime);
else
Console.WriteLine("mc2 not found in the table.");
}
}
public class ManagedClass
{
}
public class ClassData
{
public DateTime CreationTime;
public object Data;
public ClassData()
{
CreationTime = DateTime.Now;
this.Data = new object();
}
}输出：
No strong reference to mc2 exists.
