注解

TypeAccessException 方法会尝试将对象转换为不能从方法访问的类型时引发。TypeAccessException is thrown when a method attempts to cast an object to a type that is not accessible from the method. 例如,匿名托管动态方法不能访问安全关键类型,因为该方法为透明For example, an anonymously hosted dynamic method cannot access a security-critical type because the method is transparent. 如果方法包含OpCodes.Castclass强制转换为安全关键类型,或作为一个其类型参数,具有安全关键类型的泛型类型的对象的指令TypeAccessException由 JIT 编译器引发。If the method contains a OpCodes.Castclass instruction that casts an object to a security-critical type, or to a generic type that has a security-critical type as one of its type parameters, TypeAccessException is thrown by the JIT compiler.

同样,TypeAccessException使用从另一个程序集的内部类型的动态方法时引发。Similarly, TypeAccessException is thrown for a dynamic method that uses an internal type from another assembly. 一种方法可能没有访问它的包含类型、 其返回类型或其参数类型之一。A method might not have access to its containing type, its return type, or one of its parameter types.

通过使用编译的应用.NET Native.NET Native工具链可能会在运行时引发异常。Apps compiled by using the .NET Native.NET Native tool chain may throw a exception at runtime. 仅限内部的异常类型派生自TypeAccessExceptionis an internal-only exception type derived from TypeAccessException. 该异常指示应用程序成功执行所需的元数据不在运行时存在。The exception indicates that metadata needed for the successful execution of an app is not present at runtime. 不应使用try / catch块来处理异常。You should not use a try/catch block to handle the exception. 相反,应确定缺少哪些元数据,并修改应用的以确保在运行时存在。Instead, you should determine what metadata is missing and modify your app's to ensure that it is present at runtime.
