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. 出现这种情况的原因可能是调用方无权访问成员,或者目标没有定义成员等。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

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,请 catch 改为编写一条语句 ExceptionTo catch the exception in that case, write a catch statement for Exception instead.
