如何使用Visual Studio Code调试C＃代码

Question

I am a newbie to VS Code environment. I am developing a Web API in VS Code which would later be consumed from client application. Following code block does not seem to be executing so I want to check whether it is at all hitting!

 //GET: pwapi/plants/10076/features [HttpGet("{id}, {sectionArray}")] public async Task<string> Get(int id, string sectionArray){ var url="https://www.domain.com/search?apikey=<apikey>&sections="+sectionArray+"&plantid="+id; using(var client = new HttpClient()){ client.BaseAddress=new Uri(url); client.DefaultRequestHeaders.Accept.Clear(); var response=await client.GetAsync(url); //will throw an exception if not successful response.EnsureSuccessStatusCode(); string content = await response.Content.ReadAsStringAsync(); //return await Task.Run(() => JsonObject.Parse(content)); return content; } } 

URL for the above method is http://localhost:5000/pwapi/plants/10076/features

I have the overloaded method which is working fine:

 [HttpGet("{id}")] public async Task<string> Get(int id){ var url="https://www.domain.com/list?apikey=<apikey>"; using(var client = new HttpClient()){ client.BaseAddress=new Uri(url); client.DefaultRequestHeaders.Accept.Clear(); var response=await client.GetAsync(url); //will throw an exception if not successful response.EnsureSuccessStatusCode(); string content = await response.Content.ReadAsStringAsync(); //return await Task.Run(() => JsonObject.Parse(content)); return content; } } 

URL for the above method is http://localhost:5000/pwapi/plants/10076

Three questions: 1. How I can debug the code? 2. If debug is not possible (so far I have seen that debug is possible for client scripts only, I may be wrong), what is the alternative way to know where I am doing wrong? 3. If there is no alternative, please tell me why the method is not hitting.

Answer 1

If you notice your route prefix for Get overload you have a comma instead of a slash, which makes the route invalid therefore your endpoint never gets hit. Please change the route prefix to this:

[HttpGet("{id}/{sectionArray}")]

As for debugging the endpoint you just need to put a break point by either pressing F9 on the line or by clicking on the left of the line of code that you want to debug.
