MemberAccessExceptionFieldAccessExceptionMethodAccessExceptionMissingMethodException、、、和MissingFieldException的基类(.NET Native.NET Native仅限)。 MissingMemberExceptionMemberAccessException is the base class for FieldAccessException, MethodAccessException, MissingMemberException, MissingMethodException, and MissingFieldException, and (.NET Native.NET Native only). 如果找不到类成员或不允许访问成员, 则会引发这些异常。These exceptions are thrown when a class member is not found or access to the member is not permitted.

MemberAccessException由以下方法引发:MemberAccessException is thrown by the following methods:

InvokeSystem.Reflection类的、 GetValue DynamicInvoke类的和Delegate类的。 FieldInfoInvoke of the System.Reflection classes, GetValue of the FieldInfo class, and DynamicInvoke of the Delegate class.

使用.NET Native.NET Native工具链编译的应用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. 是派生自MemberAccessException的仅限内部的异常类型。is an internal-only exception type derived from MemberAccessException. 此异常表示在运行时不存在成功执行应用所需的元数据。The exception indicates that metadata needed for the successful execution of an app is not present at runtime. 不应使用try / 块来处理异常catchYou should not use a try/catch block to handle the exception. 相反, 你应该确定丢失的元数据, 并修改应用程序以确保其在运行时存在。Instead, you should determine what metadata is missing and modify your app's to ensure that it is present at runtime.

MemberAccessException使用具有值0x8013151A 的 HRESULT COR_E_MEMBERACCESS。MemberAccessException uses the HRESULT COR_E_MEMBERACCESS, that has the value 0x8013151A.
