How do I start a program with arguments when debugging

Question

I want to debug a program in Visual Studio 2008  The problem is that it exits if it doesn t get arguments  This is from the main method   if  args    null    args Length    2    args 0  ToUpper   Trim       RM          Console WriteLine  RM must be executed by the RSM         Console WriteLine  Press any key to exit program           Console Read        Environment Exit -1       I don t want to comment it out and and then back in when compiling  How can I start the program with arguments when debugging  It is set as the StartUp Project

I would suggest using the directives like the following:

        static void Main(string[] args)
        {
#if DEBUG
            args = new[] { "A" };
#endif

            Console.WriteLine(args[0]);
        }

Good luck!

My suggestion would be to use Unit Tests   In your application do the following switches in Program cs    if DEBUG     public class Program  else     class Program  endif   and the same for static Main string   args    Or alternatively use Friend Assemblies by adding    assembly  InternalsVisibleTo  TestAssembly      to your AssemblyInfo cs   Then create a unit test project and a test that looks a bit like so    TestClass  public class TestApplication        TestMethod      public void TestMyArgument                 using  var sw   new StringWriter                          Console SetOut sw      this makes any Console Writes etc go to sw              Program Main new      argument                   var result   sw ToString                 Assert AreEqual  expected   result                       This way you can  in an automated way  test multiple inputs of arguments without having to edit your code or change a menu setting every time you want to check something different

Go to Project- gt  lt Projectname gt  Properties  Then click on the Debug tab  and fill in your arguments in the textbox called Command line arguments

for  NET Core console apps you can do this 2 ways - from the launchsettings json or the properties menu  Launchsettings json  or right click the project  gt  properties  gt  debug tab on left see  quot Application Arguments  quot   this is  quot   quot   space  delimited  no need for any commas  just start typing  each space  quot   quot  will represent a new input parameter   whatever changes you make here will be reflected in the launchsettings json file

I came to this page because I have sensitive information in my command line parameters  and didn t want them stored in the code repository   I was using System Environment variables to hold the values  which could be set on each build or development machine as needed for each purpose   Environment Variable Expansion works great in Shell Batch processes  but not Visual Studio     Visual Studio  Start Options     However  Visual Studio wouldn t return the variable value  but the name of the variable   Example of Issue     My final solution after trying several here on S O  was to write a quick lookup for the Environment variable in my Argument Processor   I added a check for   in the incoming variable value  and if it s found  lookup the Environment Variable and replace the value   This works in Visual Studio  and in my Build Environment   foreach  string thisParameter in args                                if  thisParameter Contains                                             string parameter   thisParameter Substring 0  thisParameter IndexOf                            string value   thisParameter Substring thisParameter IndexOf        1                        if  value Contains                                 Workaround for VS not expanding variables in debug                         value   Environment GetEnvironmentVariable value Replace                                    This allows me to use the same syntax in my sample batch files  and in debugging with Visual Studio   No account information or URLs saved in GIT                          Example Use in Batch
