已经经历了一些框架类使用反射镜，发现了一些方法和属性有下列属性
Been going through some framework classes using reflector and noticed a number of the methods and properties have the following attribute
[TargetedPatchingOptOut("Performance critical to inline across NGen image boundaries")]
我是pretty的肯定，我也看到了上述评论别的地方，从来也没有遵循它。
I'm pretty sure I have also seen the above comment somewhere else and never followed it up.
可能有人请告诉我这是什么意思在C＃和其他方面？
Could someone please tell me what this means in the C# and any other context?
推荐答案
它告诉NGEN，这是OK内联它的应用方法，即使在不同的装配。
It tells NGen that it is OK to inline the method it's applied to even in a different assembly.
例如：
String.Equals 的 [TargetedPatchingOptOut]
您编写一个程序，调用 String.Equals
您对这个项目的最高性能运行 NGEN
NGEN将内联 String.Equals 通话，与实际code的方法替换方法调用指令。
方法调用（略）贵，所以这是一个性能提升对于经常调用的方法。
String.Equals has [TargetedPatchingOptOut]
You write a program that calls String.Equals
You run NGen on this program for maximum performance
NGen will inline the String.Equals call, replacing the method call instruction with the actual code in the method.
Method calls are (slightly) expensive, so this is a performance boost for frequently-called methods.
不过，如果微软发现在 String.Equals 安全漏洞，他们不能只更新 mscorlib.dll中，因为这会不会影响你刚才NGen'd大会。 （因为它有没有引用原机code String.Equals ）。
我认为，如果这是实际发生的，此安全更新将清零NGEN店。
However, if Microsoft finds a security hole in String.Equals, they cannot just update mscorlib.dll, because that won't affect the assembly that you just NGen'd. (Since it has raw machine code without referencing String.Equals).
I assume that if that were to actually happen, the security update would clear the NGen store.
请注意，此属性仅在.NET框架组件是有用的。你不需要在你自己的。你可以找到这里的更多信息： http://stackoverflow.com/a/14982340/631802
Note that this attribute is only useful in the .NET Framework assemblies. You don't need it in your own. You can find more information about that here: http://stackoverflow.com/a/14982340/631802
