| 1. | It manifests itself as a class - cast exception
它通过类强制转换异常来表明。 |
| 2. | On this tree causes a class - cast exception
将导致类强制转换异常。 |
| 3. | In the next article , i will discuss bug patterns related to class cast exceptions
在下一篇文章中，我将讨论与类强制转换异常有关的错误模式。 |
| 4. | Symptoms : a program that performs a recursive descent over a data structure throws a class - cast exception
症状：在数据结构上执行递归下行时抛出类强制转换异常。 |
| 5. | To avoid possible casting exceptions , you should use a conditional casting operation such as the as
为了避免可能出现的强制转换异常，应当使用条件强制转换运算，例如c #中的 |
| 6. | Instead , the error signaled at run time would be a null - pointer exception instead of a class - cast exception

| 9. | Examples include converting exception types , handling exceptions at common points such as in web application controllers , logging exceptions when they first occur , creating summary reports on errors , and isolating errors in auxiliary subsystems so that they can t affect core systems
示例包括转换异常类型、处理公共点（比如web应用程序控制器）上的异常、在异常第一次发生时进行记录、创建错误汇总报告，以及隔离辅助子系统中的错误使其不影响核心系统。 |
