Hello. Recently I was trying to find out how do I compile my .CS file (C# File with C# Code) into an EXE or DLL file for my program without installing any software. I asked some of my friends in case they know, they told me to use csc (.NET Framework Feature). It is located in C:\Windows\Microsoft.NET\Framework*system dotnet framework version*\csc.exe -- Visual C# Command Line Compiler. They did not provide command-line syntax, so here's why I ask this question.

I tried to run CSC.EXE from its own path in CMD, but I got nothing that useful... (I was using no arguments)

Can anyone provide the usage of csc.exe, for operations like compiling a C# file into a library or executable?

Note: There are no system instabilities or anything whatsoever. I need this information, it is related to my program.

I did actually refer to learn.microsoft.com to see CSC.exe syntax, but, didn't get what I need.

C#
C#
An object-oriented and type-safe programming language that has its roots in the C family of languages and includes support for component-oriented programming.

    @AbdulqadirAliyev-3681, Welcome to Microsoft Q&A, you could try the following steps to use csc.exe to convert .cs file to an exe file.

    First, please create the following .cs file in the path C:\Test\Project.

    using System;  
      
    public class HelloWorld {  
        public static void Main()   
        {  
            Console.WriteLine("Hello world!");  
            Console.ReadKey();  
      
        }  
    }  
    

    Second, please open your command prompt in your computer.

    Third, please use the following cmd to convert your .cs file to exe file.

    csc.exe -out:C:\Test\Project\Program.exe C:\Test\Project\Program.cs  
    

    Finally, you could see the output in the console window and the exe is shown in the folder.

    Hope this could help you.

    Best Regards,
    Jack

    For example, create a source file (hello.cs) like this:

    using System;  
      
    namespace MyNamespace  
    {  
      class MyProgram  
      {  
         static void Main( string[] args )  
         {  
           Console.WriteLine("Hello!");  
         }  
      }  
    }  
    

    Then execute this command:

    ā€ƒC:\Windows\Microsoft.NET\.....\csc.exe hello.cs

    (Specify the correct path). It will create the hello.exe file.
