注解

当尝试对 null 对象调用非静态方法时,将引发 TargetExceptionA TargetException is thrown when an attempt is made to invoke a non-static method on a null object. 这可能是因为调用方不具有访问成员,或者因为目标不会不中定义的成员,等等。This may occur because the caller does not have access to the member, or because the target does not define the member, and so on.

备注

此异常未包含在.NET for Windows Store 应用可移植类库,但它将引发的某些成员。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的异常,编写catch语句Exception相反。To catch the exception in that case, write a catch statement for Exception instead.
