本篇文章比较单，我们会主要详l的介绍CLR Profilerq个工具?/span>

 

基础：详解介绍Profiler的?/span>

       大家可以从这里从微Y?/span>站点下蝲CLR Profiler。一旦下载CLR Profiler之后Q我们就可以解压Q然后运行Bin文g夹中?#8220;CLRProfiler.exe”?/span>

首先我们来介l一下CLR Profiler的功能?/span>

 

       CLR Profiler实是一个不错的工具Q通过使用它，我们可以了解一?NET应用E序到底是如何用内存的Q基本上面它的功能可以分Zc?如图所C：

 

20120409210650.png

 

1. 对一?NET应用中的内存是如何分配的l出一个完整的描述。所以，我们可以看到每一U类型，Ҏ所占用的内存情c?/span>

2. 它告诉我们一个方法被调用了多次?/span>

 

       q里需要注意的是Q不要再生环境或上面的服务器站点中q行CLR ProfilerQ因为它会严重的影响E序的媄响。例如，如果我们的应用程序中包含两个ҎQfun1和fun2Q此时当我们q行CLR Profiler的时候，它会一些逻辑注入到应用程序中Q通过下面的一个图可以很清楚的看个问题：

说了q么多，我们q是来看看，如何使用CLR Profiler?/span>

 

       首先Q在使用CLR Profiler之前Q我们要清楚Q要使用q个工具来干嘛？基本上，有两点理由：查看内存的分配与使用的情况；查看Ҏ被调用次数?/span>

启动了CRLProfiler.exe之后Q选择要检查的E序Q如下图Q?/span>

此时Q应用程序就开始运行，我们可以在Profiler中看C些信息，例如应用E序占用的内容，每一代对象占用的大小{，如下Q?/span>

       其实上面的那个应用程序非常的单，只是作ؓ一个demo演示而言。上面的E序的功能就是在一个按钮的事g中调用了两个ҎQ?strong style="padding-right: 0px; padding-left: 0px; font-weight: bold; padding-bottom: 0px; margin: 0px; padding-top: 0px">UseSimpleStrings?strong style="padding-right: 0px; padding-left: 0px; font-weight: bold; padding-bottom: 0px; margin: 0px; padding-top: 0px">UseStringBuilders。这个两个方法都是在拼接字符Ԍq也是常常被用来做例子的一个场景）Q我们分别让它们拼接1000个字W串Q如下：

其中UseSimpleStrings如下Q?/span>

 

20120409211053.png

 

UseStringBuilders如下Q?/span>

       现在Q我们可以尝试着使用Profilerȝ看每个方法用多的内存。我们在E序中点L钮，好让ProfilerL集信息。然后，我们在点击Profiler?#8220;histogram”按钮Q此时我们就可以看到E序中的每一U类型的内存占用情况Q如下：

如果我们想看每一个方法在q行q程中占用的内容Q可以点?#8220;Allocation Graph”Q如下：

 

20120409211413.png

 

通过q个操作Q我们可以看C面的图：

 

20120409211458.png

 

       乍一看，可能感觉界面非常的؜乱，特别是在应用E序很大的时候。ؓ了更加看到我们想看的ҎQ我们可以通过在界面的中点d键，点击“Find Routine”Q然后选择输入qo的条Ӟ如下Q?/span>

 

20120409211523.png

 

q样可以快速的定位Q如下：

 

20120409211559.png

 

然后在方法上面双击，p一步的展开Q查看细节，如下Q?/span>

 

20120409211642.png

 

       在上图中Q我们只是看C“UseSimpleStrings”Ҏ的用内存的情况Q因个界面显C的信息比较的粗p，只是把一些内存用比较多的方法列出来了，我们可以通过点击“0(everything)”查看所以的ҎQ此时看到如下：

通过上面的图Q我们一目了然的直到内存的用情?/span>
