You will need a row comparer. We’ll keep in mind that all rows have same length: public class RowComparer : IComparer<IEnumerable<int>> { public int Compare(IEnumerable<int> x, IEnumerable<int> y) { // TODO: throw ArgumentNullException return x.Zip(y, (xItem, yItem) => xItem.CompareTo(yItem)) .Where(c => c != 0).FirstOrDefault(); } } And use it for sorting: inputRows.Select(r => r.OrderBy(x => … Read more

Other than what people already said about the try…catch…finally block, I believe what you’re looking for is try { file = new FileStream(“example.txt”, FileMode.Open); file.open(); } catch (Exception ex) { MessageBox.Show(ex.Message); } But you need to add reference to System.Windows.Forms in your project and add the using statement to your class using System.Windows.Forms; Or, if … Read more
This happens because of the string you have before, what you write is equivalent to : “the sum of the numbers you entered is :” + 5 + 10; which is the sum of a string with 2 integers, what happens when you add a number to a string is that ToString() is implicitely called … Read more
One option would be to iteratively multiply by 10 until you get a number greater than 1: public double RemoveLeadingZeros(double num) { if (num == 0) return 0; while(Math.Abs(num) < 1) { num *= 10}; return num; } a more direct, but less intuitive, way using logarithms: public double RemoveLeadingZeros(double num) { if (num == … Read more
You can use forward declaration of your class second and use a pointer. Only the implementation must know the declaration of your class Second. namespace A { class Second; // Forward declaration class First { public: First(); ~First(); private: Second* s; // Pointer on a forward class }; class Second { private: First f; }; … Read more
Well I was able to figure this out after a couple of days at it. This issue here is that Regex is that it will match a string as a whole, so if I wanted the exclude a character from a match I could do so by using Regex to drop either the first or … Read more

You can test for input success with an if: if (cin >> ch) … To ask the user to enter input again, you’ll need a loop, and you also need to call cin.clear() to restore the stream’s state: cout << “\n Enter your choice(1,2,3,9)”: cin >> ch; while (!cin) { cout << “Invalid input. Please … Read more

This appears to already be multi-threaded. Try adding logging code to the start and end of each FileGenerationForXXX method so you can see the four methods starting together and stopping separately. private void FileGenerationForITD() { eventlog1.WriteEntry(“FileGenerationForITD started.”); … eventlog1.WriteEntry(“FileGenerationForITD finished.”); } Additionally, you can knock out all of the if statements. The thread objects are … Read more
