how to run a cs file other than program.cs in consoleappln

Question

I created a console application with which it created program.cs file but I created different class within the same project with main method in it. How can run my new class? Every time I run my app, it keeps executing Program.cs in console application. Can you please direct me with right path?

Since you're having two entry points in your application, the Compiler is not able to figure out which one to execute. You may want to go through this post: http://www.csharphelp.com/2006/08/entry-point-in-c-program/ I hope it will give you an overview of your findings.

If you don't want to interfere too much with the way Visual Studio does things, just make the two highlighted additions to redirect to your main() method: using System; namespace structTesting { public class structTestClass { public struct BookStruct { public string title; public string category; public string author; public string no_of_pages; public int currentPage; public string ISBN; public string coverStyle; public BookStruct(string title, string category, string author, string no_of_pages, int currentPage, string ISBN, string coverStyle) { this.title = title; this.category = category; this.author = author; this.no_of_pages = no_of_pages; this.currentPage = currentPage; this.ISBN = ISBN; this.coverStyle = coverStyle; } public int prevPage(int currentPage) { return (currentPage - 1); } public int nextPage(int currentPage) { return (currentPage + 1); } } public static void main(String[] args) // now public { BookStruct bookStruct = new BookStruct("KidsAffection", "kids", "Geetha", "300", 20, "125-333-1234", "HardBook"); //Output Begins Console.WriteLine("title =>" + bookStruct.title); Console.WriteLine("category =>" + bookStruct.category); Console.WriteLine("author =>" + bookStruct.author); Console.WriteLine("no_of_pages =>" + bookStruct.no_of_pages); Console.WriteLine("currentPage =>" + bookStruct.currentPage); Console.WriteLine("ISBN =>" + bookStruct.ISBN); Console.WriteLine("coverStyle =>" + bookStruct.coverStyle); Console.WriteLine("previous Page=>"+bookStruct.prevPage(20)); Console.WriteLine("next Page=>"+bookStruct.nextPage(20)); } } } // program.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace structTesting { class Program { static void Main(string[] args) { structTestClass.main(args); // redirects to other main() method } } }

I was actually relying on the fact that you'd used a lower case main() in your class for my solution to work without further ado but glad you've sorted it out now :)

Hi Vulpes , Thank You very much. I resolved that issue as well by changing the project properties. Thank You All For your valuable help. Regards, Geetha

I resolved the issue using Sunny's suggestion. Thank you. The biggest problem is My bad I mentioned main as main instead of M ain. Vulpes , I tried your solution public static void Main(String[] args) { bookStruct bookStruct = new bookStruct("KidsAffection", "kids", "Geetha", "300", 20, "125-333-1234", "HardBook"); //Output Begins Console.WriteLine("title =>" + bookStruct.title); Console.WriteLine("category =>" + bookStruct.category); Console.WriteLine("author =>" + bookStruct.author); Console.WriteLine("no_of_pages =>" + bookStruct.no_of_pages); Console.WriteLine("currentPage =>" + bookStruct.currentPage); Console.WriteLine("ISBN =>" + bookStruct.ISBN); Console.WriteLine("coverStyle =>" + bookStruct.coverStyle); Console.WriteLine("previous Page=>" + bookStruct.prevPage(20)); Console.WriteLine("next Page=>" + bookStruct.nextPage(20)); } static void Main(string[] args) { Class1.Main(args); } but I am getting an error saying " Error 2 Program 'c:\geet\projects\ConsoleApplication1\ConsoleApplication1\obj\Debug\ConsoleApplication1.exe' has more than one entry point defined: 'ConsoleApplication1.Class1.Main(string[])'.

Hi, Please place your static void main method in the class which has to be run

using System; namespace structTesting { public class structTestClass { public struct BookStruct { public string title; public string category; public string author; public string no_of_pages; public int currentPage; public string ISBN; public string coverStyle; public BookStruct(string title, string category, string author, string no_of_pages, int currentPage, string ISBN, string coverStyle) { this.title = title; this.category = category; this.author = author; this.no_of_pages = no_of_pages; this.currentPage = currentPage; this.ISBN = ISBN; this.coverStyle = coverStyle; } public int prevPage(int currentPage) { return (currentPage - 1); } public int nextPage(int currentPage) { return (currentPage + 1); } } static void main(String[] args) { BookStruct bookStruct = new BookStruct("KidsAffection", "kids", "Geetha", "300", 20, "125-333-1234", "HardBook"); //Output Begins Console.WriteLine("title =>" + bookStruct.title); Console.WriteLine("category =>" + bookStruct.category); Console.WriteLine("author =>" + bookStruct.author); Console.WriteLine("no_of_pages =>" + bookStruct.no_of_pages); Console.WriteLine("currentPage =>" + bookStruct.currentPage); Console.WriteLine("ISBN =>" + bookStruct.ISBN); Console.WriteLine("coverStyle =>" + bookStruct.coverStyle); Console.WriteLine("previous Page=>"+bookStruct.prevPage(20)); Console.WriteLine("next Page=>"+bookStruct.nextPage(20)); } } }
