C#同级catch块和finally块中全都抛出异常，上一级优先捕获finally块中的异常。

测试代码：

1 using System; 2  3 namespace test 4 { 5     class Program 6     { 7         static void Main(string[] args) 8         { 9             try10             {11                 try12                 {13                     throw new Exception();14                 }15                 catch (Exception)16                 {17                     throw new Exception("catch块儿");18                 }19                 finally20                 {21                     throw new Exception("finally块儿");22                 }23             }24             catch (Exception e)25             {26                 Console.WriteLine(e.Message);27             }28             Console.Read();29         }30     }31 }
