使用“动态”时，RuntimeBinder中的泄漏关键字与__ComObject [英] Leak in RuntimeBinder when using "dynamic" keyword with __ComObject

问题描述

在C＃中使用__ComObject实例使用dynamic关键字时，有没有人知道是否有防止RuntimeBinder中的内存泄漏的方法？

我得到以下代码：

  var t = Type.GetTypeFromCLSID（new Guid（BB06C0E4-D293-4f75-8A90-CB05B6477EEE））; 
 while（true）
 {
 dynamic o = System.Activator.CreateInstance（t）; 
 Marshal.ReleaseComObject（o）; 
} 
  

这会泄漏LocalVariableSymbol类实例（以及Microsoft.CSharp.RuntimeBinder中的其他类实例）。语义命名空间）。

用对象替换动态，即：

  object o = System.Activator.CreateInstance（t）; 
  

修复漏洞，但我宁愿继续使用动态（实际代码复杂得多，使用动态）。

我知道RuntimeBinder单例缓存数据，这会导致泄漏，但是你知道是否有任何方法来清除缓存等非常感谢！

解决方案

我的案例中的解决方案是替换：

  dynamic o = System.Activator.CreateInstance（t）; 
  

with：

 code> object o = System.Activator.CreateInstance（t）; 
 dynamic d = o; 
  

应用了解决方法，内存泄漏不再发生。

Does anybody know if there is a way of preventing a memory leak in RuntimeBinder when using "dynamic" keyword with __ComObject instances in C#?

I got the following code:

var t = Type.GetTypeFromCLSID(new Guid("BB06C0E4-D293-4f75-8A90-CB05B6477EEE"));
while (true)
{
    dynamic o = System.Activator.CreateInstance(t);
    Marshal.ReleaseComObject(o);
}

This leaks LocalVariableSymbol class instances (and other from the Microsoft.CSharp.RuntimeBinder.Semantics namespace).

Replacing "dynamic" with "object" i.e.:

    object o = System.Activator.CreateInstance(t);

fixes the leak but I'd prefer to keep using dynamic (the actual code is much more complex and makes use of "dynamic").

I know the RuntimeBinder singleton caches the data and this causes the leak but do you know if there's any way to cleanup the cache etc.?

Many thanks!

解决方案

The solution in my case was to replace:

dynamic o = System.Activator.CreateInstance(t);

with:

object o = System.Activator.CreateInstance(t);
dynamic d = o;

The memory leak no longer occurs having the workaround applied.
