Debugging C# Code in Visual Studio | Mosh

Geeez!!! Learned more from the constant ads

Recorded 8 years ago, still actual 😅

Hi, this is a awesome tutorial! My first impression is that the syntax of C# looks similar that of JavaScript and PHP.

Awesome video

Best debugging video I've ever seen!
Thank you, Mosh 😇

Sir you easily identified problems in program. but some peoples only made for subscribers and views . but sir you really learn from heart.

Your visual studio looks different than mine. Do you have any visual mods/settings you’d recommend? Thanks!

When we are excuting the statement var min= list[0] then the value of min should be 1 but why it's showing 0? Anyone who got this

hello can i get help how i can debug a file that was made after the main file
when i debug a file it only runs the first file of cpp and then it completes it
it doesn't run the second file that i have coded.
if i wanted my second file to be debug i made a new project and make a new main file and the past my code there to debug.
or it compels me write all the codes in one file and debug it.(too much code under one file is really messy)
is there easy and simpler way to debug a particular file i want?

using System;
using System.Collections.Generic;

namespace CSharpFundamental
{
class Program
{
static void Main(string[] args)
{
var numbers = new List<int> { 8, 9, 10, 11, 12, 13 };
var smallests = GetSmallests(numbers, 3);

foreach(var number in smallests)
Console.WriteLine(number);
Console.ReadLine();
}

public static List<int>GetSmallests(List<int> list, int count)
{
var smallests = new List<int>();

while(smallests.Count < count)
{
var minim = GetSmallest(list);
smallests.Add(minim);
list.Remove(minim);
}
return smallests;
}
public static int GetSmallest(List<int> list)
{
//Assume the first number is the smallest
var min = list[0];

for (var i = 1; i < list.Count; i++)
{
if (list[i] < min)
min = list[i];
}
return min;
}
}
}

excellent explanation, as ALWAYS from Mosh! Thanks.

Clear cut explanation

Thank You

Very helpful! Thank you :)

Thank you for this video! You always do such a great job explaining everything! So far, I have only watched your videos for this and data structures\Big O notation. I will be back for more.

Thank you, bro.

I wish this video has sub language. It's hard for me to understand all :v. I maybe have to watch this many times.

A much better solution would be to post decriment the count variable in the while loop. Then you don't need all the convoluted if's and it will run without errors. If you enter return 17 lowest numbers and there are only 3 in the list.... the code returns 3! My solution causes not crashes even if you enter a neg number for the return number. It just returns an empty list//// no crashes no problems. I do not like ode that creates crashes!

Very good explanation sir. Thank you.

Hi, is there reason for not include auto caption or subtitle?

Can I get an F for respect for all those unlucky people who didn't know that there are C# tutorials from Mosh even after his "Learn C# Basics in 1 Hour" video?

Instead of checking for count<0 and throwing an exception, would't it be more expressive to just have count be a uint?
And why disallow count == 0? That seems to me like a perfectly legit situation.

Awesome Debugging and Defensive programming tutorial. Would like to request that you create a tutorial for error handling, thank you!

Thank you Mosh for explaining in such a clear language, step by step all the small details.

man nice work i watched 8 videos and none of them explained the terms like step in and step out but after watching your video I got thanks to you and your hard work

Could you explain how to have a Application.Tests.Console launched Application.ConsoleUI AND still get debugging abilities in the non-test?

How do I get help with School assignments? I am a registered subscriber on your C# tutorial website.

I know that this algorithm is purely illustrative, but does C# not have packages like collections.Counter from python?
I was messing around with things like this when I started coding, then found out in that collections and itertools had all those functions built already.

I always get happy when I search for C# guides and tips and Mosh shows up in the results. Big up!

Good stuff! Thanks :)

Some of the most in-depth, easy-to-digest information on the subject I've seen. Thanks!

thx, you are talanted teacher

A concise and informative video. Thank you so much!

Hello. I tried to solve the problem before going to the next video, what do you think of my solution? The 2nd & 3rd lines tell the user about the issue and ask for a new count-er from 1 to the size of the list. Then I check if the input can be parsed to integer if yes continue normally but if not then ask again. This way even if the input is a letter, symbol, a space or return key press, it will not be an issue.
while(count < 1 || count > list.Count){
Console.WriteLine("\n Az elvono ertek vagy kissebb mint 1 vagy nagyobb mint ahany szam van.");
Console.WriteLine(" Irjon be egy elvono erteket 1-tol " + list.Count + "-ig:");
var uj_szam = Console.ReadLine();
bool uj_ = Int32.TryParse(uj_szam, out int count_);
if(uj_ == false){ continue; }
count = Int32.Parse(uj_szam);
Console.Write("\n Ujra szamolunk. \n"); }

Thanks too much

deploy=eset

you are simply brilliant. I would like subscribe one of your trainning course but its in dollar currency. I am from UK. How would I subscribe it out of USA.

Much appreciated was putting print statements all over the place before.

Your lesson don't follow any rhythm, jumping from scenario to scenario just confusing beginners.

Your tutorial are awesome !! I have completed c# console basics now what should i do next .

what about debugging in c

can u make videos on ethnic haking

Watch window option is missing in my visual studio.
Which version of visual studio are you using?

I know i might be bugging you right now, but the theme is really important to me, because it helps my vision, i have been putting on lenses for i don't know over 2 decades now, and just recently i started having migraines when i look at too bright a source of light, and most of the themes i use in visual studio even the dark one the white font-color is still too bright, so i just wanted to know more about the settings of the editor, if there is anything else you added after installing resharper.

Hi
I am having a error message in the code: Cannot convert from 'System.Collection.Generic.List<int> to 'int'
Cannot implicity convert 'int' to 'System.Collections.Generic.List<int> . What does it mean?

Hello Mosh! Thanks for the quick video. I have a few questions.

1) So with the Call Stack, as you move back up the stack it shows you what line it last executed in that method before entering the new method? If so that seems like that would be good so that you don't have to read the whole method or wonder where it began to crash. If it is a long method then you can spend a lot of time trying to figure out where and what caused it.

2) How you know when you should throw an exception verses just alerting the user that his number is invalid? There is a rule of thumb or an article I should read?

3) How do I know which exception to throw? Do i just create the error and then throw the same exception? Should i learn or memorize a list of exceptions?

Thanks!

Great Job Mosh , Waiting for The Entity Framework course.
I'm curious when u will upload it? :)
