此程序需要安裝ftp服務器，安裝adobe reader（我這里使用的adobe reader9.0）

1、部署ftp服務器

將ftp的權限設置為允許匿名訪問，部署完成

2.安裝adobe reader9.0閱讀器

3、設置visual studio 加載adobe reader的插件

工具箱-選擇項-com組件

選擇adobe PDF Reader 確定完成

到此可以在winform中使用閱讀器了

文檔加載如下代碼可完成文檔的加載顯示：還是相當簡單的。

axAcroPDF1.src =”c:\wyDocument.pdf”;

4、開始寫代碼實現功能

工程結構如下：

主窗體界面：

后端代碼如下：

using System; using System.Collections.Generic; using System.ComponentModel; using System.Configuration; using System.Data; using System.Drawing; using System.IO; using System.Linq; using System.Net; using System.Text; using System.Threading.Tasks; using System.Windows.Forms;namespace myPDFDmeo {public partial class getFileForm : Form{FtpUtility ftp = new FtpUtility();List<string> fileNames = new List<string>();public getFileForm(){InitializeComponent();}//獲取遠程計算機文件private void button1_Click(object sender, EventArgs e){//遠程服務器地址string remoteIpAddress = ConfigurationManager.AppSettings["RemoteIpAddress"].ToString();//本地目錄string localPath = ConfigurationManager.AppSettings["LocalDirectory"].ToString();ftp.FtpExplorer("anonymous", "chenshengwei@163.com", remoteIpAddress);//獲取ftp當前目錄下所有文件列表List<FileStruct> filesList = ftp.GetFileList();//獲取本地文件夾的所有文件名fileNames = ftp.ProcessDirectory(localPath);//刪除本地文件夾的所有文件for (int i = 0; i < fileNames.Count; i++){string localFile = localPath + fileNames[i].ToString();//刪除當前文件if (File.Exists(localFile)){File.Delete(localFile);}}//下載遠程服務器服務器文件for (int i = 0; i < filesList.Count; i++){ftp.DownloadFtp(localPath, filesList[i].Name, remoteIpAddress, "anonymous", "chenshengwei@163.comm");}//綁定文件列表到comboxcomboBox1.DataSource = filesList;comboBox1.DisplayMember = "Name";}//瀏覽private void button2_Click(object sender, EventArgs e){string current = ((FileStruct)comboBox1.SelectedItem).Name;//將文件名稱傳入pdfViewForm p = new pdfViewForm(current);p.Show();}} }

顯示的閱讀器窗體：

直接拖上adobe reader組件 即可 設置窗體初始化最大化屬性? 設置reader組件的dock屬性-fill

后端代碼如下：

using System; using System.Collections.Generic; using System.ComponentModel; using System.Configuration; using System.Data; using System.Drawing; using System.IO; using System.Linq; using System.Net; using System.Text; using System.Threading.Tasks; using System.Windows.Forms;namespace myPDFDmeo {public partial class pdfViewForm : Form{private string parthPdfFile { get; set; }string localPath = ConfigurationManager.AppSettings["LocalDirectory"].ToString();public pdfViewForm(string currentfileName){InitializeComponent();this.parthPdfFile = currentfileName;}private void Form1_Load(object sender, EventArgs e){axAcroPDF1.src = localPath + parthPdfFile.ToString();}} }

下面是ftp訪問遠程主機獲取文件的核心實現類了

說明：下載文件時文件名包含空格的話，會有問題，今天沒時間改正了。

?

下面是配置文件中使用的兩個簡單的配置了：

<?xml version="1.0" encoding="utf-8" ?> <configuration><startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /></startup><appSettings><add key="RemoteIpAddress" value="127.0.0.1"/><add key="LocalDirectory" value="E:\down\"/></appSettings> </configuration>

至此，程序基本完成了，細節問題以后再改吧
