CLR via C# 讀書筆記 6-3 跨域訪問的效能問題

以下代碼示範了跨域訪問的效能問題

大約不跨域比跨域快100多倍....

 

代碼

 AppDomain newDomain = AppDomain.CreateDomain("remote application domain", null, null);
            MarshalByRefType local = new MarshalByRefType();
            MarshalByRefType remote = (MarshalByRefType)newDomain.CreateInstanceAndUnwrap(Assembly.GetEntryAssembly().FullName, "TestConsole.MarshalByRefType");
            Stopwatch sw = null;
int length = 10000000;
int temp;

            sw = Stopwatch.StartNew();
for (int i = 0; i < length; i++)
            {
//local.SetValue(i);
                temp=local.GetValue();
            }
            Console.WriteLine(sw.ElapsedMilliseconds);

            sw = Stopwatch.StartNew();
for (int i = 0; i < length; i++)
            {
//remote.SetValue(i);
                temp = remote.GetValue();
            }
            Console.WriteLine(sw.ElapsedMilliseconds);
return;
