备注

Windows 应用商店应用可移植类库中未包含此异常, 但它由某些成员引发。This exception is not included in the .NET for Windows Store apps or the Portable Class Library, but it is thrown by some members that are. 若要在这种情况下捕获异常, catch请改MemberAccessException为编写一条语句。To catch the exception in that case, write a catch statement for MemberAccessException instead.

此异常在以下情况下引发:This exception is thrown in situations such as the following:

  • 不能通过使用反射从部分受信任的代码访问的私有、受保护的或内部方法。A private, protected, or internal method that would not be accessible from normal compiled code is accessed from partially trusted code by using reflection.

  • 安全关键方法可从透明代码访问。A security-critical method is accessed from transparent code.

  • 类库中某方法的访问级别已更改, 并且未重新编译引用该库的一个或多个程序集。The access level of a method in a class library has changed, and one or more assemblies that reference the library have not been recompiled.

备注

从开始, 公共语言运行时在部分信任情况下运行应用程序代码时将其视为透明。 .NET Framework 4.NET Framework 4Beginning with the .NET Framework 4.NET Framework 4, the common language runtime treats application code as transparent when it is run with partial trust. 请参阅反射的安全注意事项See Security Considerations for Reflection.

MethodAccessException使用具有值0x80131510 的 HRESULT COR_E_METHODACCESS。MethodAccessException uses the HRESULT COR_E_METHODACCESS, that has the value 0x80131510.
