If an exception occurs within the try block, the program will immediately move to the catch block.<\/p>\n<p>The catch block is used to catch and handle exceptions thrown in the try block. You can write logic in the catch block to handle exceptions, such as logging or displaying error messages to the user.<\/p>\n<p>The finally block is a block of code that is executed after the try and catch blocks. The code in the finally block will execute regardless of whether an exception occurs. Typically, cleanup operations such as closing open files or releasing resources are performed in the finally block.<\/p>\n<p>Here is an example code:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-keyword\">try<\/span>\r\n{\r\n    <span class=\"hljs-comment\">\/\/ \u53ef\u80fd\u5f15\u53d1\u5f02\u5e38\u7684\u4ee3\u7801<\/span>\r\n}\r\n<span class=\"hljs-keyword\">catch<\/span> (Exception ex)\r\n{\r\n    <span class=\"hljs-comment\">\/\/ \u5904\u7406\u5f02\u5e38\u7684\u903b\u8f91<\/span>\r\n    Console.WriteLine(<span class=\"hljs-string\">\"\u53d1\u751f\u4e86\u5f02\u5e38\uff1a\"<\/span> + ex.Message);\r\n}\r\n<span class=\"hljs-keyword\">finally<\/span>\r\n{\r\n    <span class=\"hljs-comment\">\/\/ \u6e05\u7406\u64cd\u4f5c<\/span>\r\n    Console.WriteLine(<span class=\"hljs-string\">\"finally\u5757\u4e2d\u7684\u4ee3\u7801\"<\/span>);\r\n}\r\n<\/code><\/pre>\n<p>In the example above, if an exception is raised in the try block, the program will jump to the catch block and execute the logic within it. Then, regardless of whether an exception occurs, the code within the finally block will be executed.<\/p>\n<p>Please note that in the catch block, the parentheses after catch can specify the specific type of exception to catch.
