创建方法

Create a Method

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;
    }

按钮点击事件调用此方法

Call this method on button click event

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

如何使用C＃压缩Javascript文件？

Hi, Check this answer, it may be helpful to you,
How to compress Javascript files using C#?

您必须使用AJAXMINIFY dll Microsoft Ajax Minifier [ ^ ]

使用以上DLL你有调用方法如

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

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

它将返回缩小的脚本

您可以将它用作

It will return the minified script
You can use it as

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();
    }
}

传递参数的语法

Syntax to pass parameter

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

传递命令行参数，例如

Pass command line argument like

jsmin jquery-1.4.4.js jquery.min.js
