static void Main(string[] args)
{
if (args == null || (args != null && args.Length < 2))
{
Console.WriteLine("Usage: jsmin <file1[,file2,filen]> <outfile>");
return;
}

var argc = args.Length;

if (File.Exists(args[argc - 1]))
{
if (File.GetAttributes(args[argc - 1]) == FileAttributes.ReadOnly)
File.SetAttributes(args[argc - 1], FileAttributes.Normal);
}

using (var sw = new StreamWriter(args[argc - 1]))
{
for (var i = 0; i < argc - 1; ++i)
{
string source = String.Empty;
try
{
source = File.ReadAllText(args[i]);
}
catch (IOException)
{
Console.WriteLine("File \"{0}\" was not found.", args[i]);
continue;
}

sw.WriteLine((new Minifier()).MinifyJavaScript(source));
/* css */
//sw.WriteLine((new Minifier()).MinifyStyleSheet(source, new CssSettings { ColorNames = CssColor.Hex }));
}
sw.Flush();
}
}

THIS IS what they have given , i tried to run this in cosole app , but not sure how args will receive the arguments , it shows 0 length

You have to use AJAXMINIFY dll Microsoft Ajax Minifier[^]
Using above DLL you have call method like

(new Minifier()).MinifyJavaScript(source);

It will return the minified script
You can use it as

C#

static void Main(string[] args)
{
    if (args == null || (args != null && args.Length < 2))
    {
        Console.WriteLine("Usage: jsmin <file1[,file2,fileN]> <outfile>");
        return;
    }
    var argc = args.Length;
    if (File.Exists(args[argc - 1]))
    {
        if (File.GetAttributes(args[argc - 1]) == FileAttributes.ReadOnly)
            File.SetAttributes(args[argc - 1], FileAttributes.Normal);
    }

    using (var sw = new StreamWriter(args[argc - 1]))
    {
        for (var i = 0; i < argc - 1; ++i)
        {
            string source = String.Empty;
            try
            {
                source = File.ReadAllText(args[i]);
            }
            catch (IOException)
            {
                Console.WriteLine("File \"{0}\" was not found.", args[i]);
                continue;
            }
            sw.WriteLine((new Minifier()).MinifyJavaScript(source));      
        }
        sw.Flush();
    }
}

Syntax to pass parameter

jsmin <file1[,file2,fileN]> <outfile>

Pass command line argument like

C#

jsmin jquery-1.4.4.js jquery.min.js

this is the code i have tried in console application by adding dll , but then when application strats at main , in in first line args lengths 0 , then it simply prints the first line on console and returns ,, thats it

you have to call this console application exe from Commandline .
Like if your application is ConsoleApplication1 then
in command prompt write
[Full Path to your exe] jsmin [input File Path with FileName] [Output File Path with FileName]

NO , THATS OK , MY QUESTION IS CAN I GENERATE ALL THIS THING IN CODE ONLY ,, DONT WANT TO USE COMMAND .. I WANT TO HANDLE FROM DODE ONLY

Then you have to change the implementation. Replace main method with a customized method which will take inputFilePath, OutputFilePath. Make a Windows form with two textboxes for inputFilePath and outputFilePath and one button . Call the customized method on button click. passtextboxes value in that method.

OK , THIS IS WHAT I HAVE TRIED , CAN YOU PLEASE HELP ME ...

{
Console.WriteLine("Usage: jsmin ~/Sourse/CustomerLocation.js jquery.min.js");

}

var argc = args.Length;

if (File.Exists(args[argc - 1]))
{
if (File.GetAttributes(args[argc - 1]) == FileAttributes.ReadOnly)
File.SetAttributes(args[argc - 1], FileAttributes.Normal);
}

using (var sw = new StreamWriter(args[argc - 1]))
{
for (var i = 0; i < argc - 1; ++i)
{
string source = String.Empty;
try
{
source = File.ReadAllText(args[i]);
}
catch (IOException)
{
Console.WriteLine("File \"{0}\" was not found.", args[i]);
continue;
}

sw.WriteLine((new Minifier()).MinifyJavaScript(source));

Create a Method

C#

static string MiniFyJS(string inputFilePath, string outFilePath)
    {
        string _result = string.Empty;
        if (!string.IsNullOrEmpty(inputFilePath) && !string.IsNullOrEmpty(outFilePath))
        {
            using (var sw = new StreamWriter(outFilePath, false))
            {
                string source = String.Empty;
                try
                {
                    source = File.ReadAllText(inputFilePath);
                }
                catch (IOException)
                {
                    _result = inputFilePath + "File was not found.";
                }
                sw.WriteLine((new Minifier()).MinifyJavaScript(source));
                sw.Flush();
                _result = "Success";
            }
        }
        else
        {
            _result = "Usage: jsmin <file1[,file2,fileN]> <outfile>";
        }
        return _result;
    }

Call this method on button click event

C#

string inputFile = @"D:\JSFiles\calander.js";
       string outFile = @"D:\MinifiedJSFiles\calander.min.js";
       string result = MiniFyJS(inputFile, outFile);
