查询词典 catch-22

Catch block returns it the address where control should be transferred in the function after try-catch block.

catch块返回它的地址，控制应当在转让后的功能try - catch块。

In summer , sometimes we catch butterflies with a net.

备注： catch 的本句中的意思，是"捕捉"的意思

If no matching catch is found, then the program calls the library terminate function.

如果找不到匹配的 catch，程序就调用库函数 terminate。

Certainly, the programmer could wrap every line of code that uses a dictionary indexer with a try-catch block, or at least some outer method, but even then, the exception does not tell you the key that caused the exception.

当然，程序员可以总结每行代码，使用的尝试字典索引- catch块，或至少一些外部方法，但即使如此，该异常并没有告诉你的关键导致异常。

If the specifier is not a reference, then the catch object is a copy of the exception object. If the catch object in an object of the base type and the exception object has derived type, then the exception object is sliced down ( Section 15.3.1, p. 577) to its base-class subobject.

如果异常说明符不是引用，则 catch 对象是异常对象的副本，如果 catch 对象是基类类型对象而异常对象是派生类型的，就将异常对象分割（第 15.3.1 节）为它的基类子对象。

Because the exception_thrown event is dispatched from within the catch block, we can rethrow and catch the exception in a custom reaction

因为 exception_thrown 事件是从 catch 块中被分派的，所以我们可以在一个定制的反应中重新抛出和捕获异常

A rethrow is valid only from inside a catch clause, or in a function called directly or indirectly from a catch. Its effect is to rethrow the exception object that it received.

只有捕获子句或者从 catch 直接或间接调用的函数中的重新抛出才有效，其效果是将接到的异常对象重新抛出。

When a catch parameter is a base type, then we cannot know the actual type thrown by a rethrow expression. That type depends on the dynamic type of the exception object, not the static type of the catch parameter.

当 catch 形参是基类类型的时候，我们不知道由重新抛出表达式抛出的实际类型，该类型取决于异常对象的动态类型，而不是 catch 形参的静态类型。

As soon as a catch clause that can handle the exception is found, that catch is entered, and execution continues within this handler.

只要找到能够处理异常的 catch 子句，就进入该 catch 子句，并在该处理代码中继续执行。
