How to compile C# application through Command Prompt

Question

I have one folder. In that I have three cs files.

Demo.cs

using System;

namespace Demo
{
    public class Test
    {
        public static Entity entity = new Entity();

        public static void Main(string[] args)
        {
            var objectHandler = Activator.CreateInstance(null,
                                                         args);
            var obj = objectHandler.Unwrap();
            entity.GetAnnotation(obj.GetType());
        }
    }
}

Entity.cs

using System;

namespace Demo
{
    public class Entity
    {
        public void GetAnnotation(Type classname)
        {
            Attribute[] dataAnnotationlist = Attribute.GetCustomAttributes(propInfo);
            foreach (var dataannotationAttribute in dataAnnotationlist)
            {
                //some operation to get annotation property from Employee.cs class
            }
        }
    }
}

Employee.cs

using System.ComponentModel.DataAnnotations;

namespace Demo
{
    public class Employee
    {
        [Display(Name = "name")]
        public string name { get; set; }
    }
}

I have created XML file format from class file (Employee.cs) using reflection. But error occurred when try to run through Command Prompt. It runs in visual studio.

I want to run Test.cs, Entity.cs using command prompt with passing "Employee.cs" as a string parameter to Main method. Now, I have passed hard coded as,

System.Runtime.Remoting.ObjectHandle objectHandler = Activator.CreateInstance(null, "Demo.Employee");

Its working fine but how to pass it through command.

Error Occurred is:

Entity.cs(8,29): error CS0234: The type or namespace name 'DataAnnotations' does not exist in the namespace 'System.ComponentModel' (are you missing an assembly reference?) Entity.cs(9,19): error CS0234: The type or namespace name 'Objects' does not exist in the namespace 'System.Data' (are you missing an assembly reference?) Employee.cs(6,33): error CS0234: The type or namespace name 'DataAnnotations' does not exist in the namespace 'System.ComponentModel' (are you missing an assembly reference?)

and it also shows error for "DataAnnotations" and "Objects".

how can i solve this problem?

One option to simply build .csproj with MSBUILD .

More entertaining is to configure all dependencies yourself via command line arguments of csc. For your immediate error you need to add references with /r: command similar to following

 csc /out:Test.exe /r:System.ComponentModel.DataAnnotations.dll *.cs

For more details on command line arguments of csc check help csc /? or on MSDN CSC command line options and Building with CSC .
