LoaderOptimizationAttribute 类

定义

用于为可执行应用程序的主方法设置默认的加载程序优化策略。Used to set the default loader optimization policy for the main method of an executable application.

public ref class LoaderOptimizationAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Method)]
public sealed class LoaderOptimizationAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Method)]
[System.Runtime.InteropServices.ComVisible(true)]
public sealed class LoaderOptimizationAttribute : Attribute
type LoaderOptimizationAttribute = class
    inherit Attribute
Public NotInheritable Class LoaderOptimizationAttribute
Inherits Attribute
继承
LoaderOptimizationAttribute
属性

注解

只能对可执行应用程序的 main 方法设置 LoaderOptimizationAttribute,并在所有其他方法中忽略。The LoaderOptimizationAttribute can only be set on the main method for an executable application and is ignored on all other methods.

使用 LoaderOptimization 枚举值指定 LoaderOptimizationAttribute 特性,该枚举值向加载器通知要为其优化的应用程序的类型: SingleDomainMultiDomainMultiDomainHostThe LoaderOptimizationAttribute attribute is specified with a LoaderOptimization enumeration value, which tells the loader what type of application to optimize for: SingleDomain, MultiDomain, or MultiDomainHost.

此属性只是对加载程序的提示,不影响程序的行为。This attribute is only a hint to the loader and does not affect program behavior.

备注

如果为 AppDomain设置了自定义代码访问安全策略,则通过使用 SetAppDomainPolicy 属性,并使用 MultiDomain 标志创建 AppDomain,该效果与指定 MultiDomainHost 标志相同;也就是说,只共享 GAC 中的程序集。If custom code access security policy is set for the AppDomain, by using the SetAppDomainPolicy property, and the AppDomain is created using the MultiDomain flag, the effect is the same as specifying the MultiDomainHost flag; that is, only assemblies in the GAC are shared. 发生这种情况时,加载程序不会引发异常,并且应用程序不会遇到与 MultiDomain 标志关联的性能提升。When this occurs, the loader does not throw an exception and the application does not experience the performance gains associated with the MultiDomain flag.
