【转载】推荐5款超实用的.NET性能分析工具 5 Good and useful .NET Profilers

虽然.NET框架号称永远不会发生内存泄漏，原因是引入了内存回收机制。但在实际应用中，往往我们分配了对象但没有释放指向该对象的引用，导致对象永远无法释放。最常见的情况就是给对象添加了事件处理函数，但当不再使用该对象时却没有将该函数从对象的事件handler中减掉。另外如果分配了非托管内存，而没有手工释放，GC同样无能为力。所以当.NET应用发生内存泄漏后如何跟踪应用的内存使用情况，定位到程序设计中的缺陷显得非常重要。下面想大家推荐5款非常实用的性能分析、内存优化工具。觉得让你收获满满！

1.JetBrains dotTrace

JetBrains dotTrace是一款性能和内存分析工具，它可以帮助你优化应用程序性能指标，支持.NET 1.0版本到4.5，快速分析程序瓶颈，找出影响效率的代码。官方网站上面有10天试用版，大家可以点击下载使用。
