1 using System; 2 using System. collections. generic; 3 using System. linq; 4 using System. text; 5 6 namespace Test06 7 {8 class Program 9 {10 static void Main (string [] args) 11 {12 try13 {14 int a = 1; 15 ulong B = 5; 16 int c = a + B; 17 Console. writeLine (c); 18 Console. readLine (); 19} 20 catch (Exception ex) 21 {22 Console. writeLine (ex. message); 23 Console. readLine (); 24} 25} 26} 27}

Failed to execute as expected, but found "a generation error occurred. Whether to continue and run the previous generation successfully. "find out the problem.

After understanding it, I got a preliminary conclusion: the compilation code is not passed, let alone the execution,

Therefore, exception handling refers to an exception in program execution. After a corresponding exception occurs, an exception is displayed.

Thank you for your criticism!
