WebDev.WebServer 学习

     自从Vs2005起，Vs开发环境便自带了WebDev.WebServer，就是这个图标，它实际上是一个小型的Web服务器，专用于.net平台。大家经常调试程序它还是相当的方便，经过小小的配置就可以指向某个文件夹，使该文件夹成为网站目录已供访问。
    WebDev.WebServer确实很轻便，同时它本身是.net程序，才2个文件，作为测试和演示环境是非常的好用，在xp也能很好的运行，Xp的IIS5实在是不方便用。
    但是自带的WebDev.WebServer只能用于本机，那是因为MS对其进行了限制，因为作出它的目的，本身是为了Vs的开发更方便而已，但是很多测试也是基于网络的，至少你不希望别人测试一些网站，总得来用你的电脑吧。
    WebDev.WebServer一共是两个文件，一个是WebDev.WebServer.exe，另一个是WebDev.WebHost.dll，另外说一下WebDev.WebServer是安装开发环境才有的，不是安装.net framework里面的东东，所以你提取这两个文件都需要已经安装有开发环境下来进行。

        }
    }

在StartExamples项目中加入 WaitMessageForm 窗体加入以下代码：

public class WaitMessageForm : Form
{
    private IContainer components;
    private Label label1;

    public WaitMessageForm()
    {
        this.InitializeComponent();
    }
    private void InitializeComponent()
    {
        ComponentResourceManager manager = new ComponentResourceManager(typeof(WaitMessageForm));
        this.label1 = new System.Windows.Forms.Label();
        this.SuspendLayout();
        // 
        // label1
        // 
        this.label1.AutoSize = true;
        this.label1.Font = new System.Drawing.Font("Microsoft Sans Serif", 12F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
        this.label1.Location = new System.Drawing.Point(26, 26);
        this.label1.Name = "label1";
        this.label1.Size = new System.Drawing.Size(517, 20);
        this.label1.TabIndex = 0;
        this.label1.Text = "Please wait while the ASP.NET Development Server is started...";
        this.label1.UseWaitCursor = true;
        // 
        // WaitMessageForm
        // 
        this.AccessibleDescription = "ASP.NET Development server loader";
        this.AccessibleName = "Start Examples";
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Inherit;
        this.AutoScaleDimensions = new SizeF(6f, 13f);
        this.AutoScaleMode = AutoScaleMode.Font;


        this.CausesValidation = false;
        this.ClientSize = new System.Drawing.Size(575, 70);
        this.ControlBox = false;
        this.Controls.Add(this.label1);
        this.FormBorderStyle = FormBorderStyle.None;
        this.Name = "WaitMessageForm";
        this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
        this.Text = "Loading...";
        this.UseWaitCursor = true;
        this.ResumeLayout(false);
        this.PerformLayout();

    }
    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        Timer timer = new Timer();
        timer.Interval = 0xfa0;
        timer.Tick += new EventHandler(this.closeTimer_Tick);
        timer.Start();
    }
    private void closeTimer_Tick(object sender, EventArgs e)
    {
        ((Timer)sender).Stop();
        ((Timer)sender).Dispose();
        base.Close();
    }
    protected override void Dispose(bool disposing)
    {
        if (disposing && (this.components != null))
        {
            this.components.Dispose();
        }
        base.Dispose(disposing);
    }

快速启动WebDev.WebServer的方法

直接通过文件夹的快捷菜单来启动WebDev.WebServer。

 

简单来说就是建立一个注册表文件，写入下列内容：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREClassesFoldershellVS2005 WebServer]
@="启动Web服务器"

[HKEY_LOCAL_MACHINESOFTWAREClassesFoldershellVS2005 WebServercommand]
@="C:\Windows\Microsoft.NET\Framework\v2.0.50727\Webdev.WebServer.exe /port:8080 /path:"%1""

　　注意这里是依照安装了VS2005的情况，如果是VS2008的话，Webdev.WebServer.exe的目录变了，应当做如下改写：

[HKEY_LOCAL_MACHINESOFTWAREClassesFoldershellVS2008 WebServer]
@="启动Web服务器"

[HKEY_LOCAL_MACHINESOFTWAREClassesFoldershellVS2008 WebServercommand]
@="C:\Program Files\Common Files\Microsoft Shared\DevServer\9.0\Webdev.WebServer.exe /port:8080 /path:"%1""

　　如果安装VS的时候没有选择默认的安装目录，请自行修改以上内容。

　　建立这个注册表文件以后，只要双击写入到注册表就可以了，想要启动，只要在文件夹上单击右键就OK了。

　　这个时候可以看到Webdev.WebServer已经启动，打开浏览器就可以访问了。

  

 

见可以写一个bat文件，内容为：
set path=%path%;C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
WebDev.WebServer.EXE /path:”C:\Inetpub\wwwroot”
这样每次启动就比较方便了。
