1.下载print2flash3 并且安装print2flash3
2.转换工具类
（1）需要导入using Print2Flash3; 这个程序集
using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using Print2Flash3;
using System.IO;
using System.Collections.Generic;
namespace WebThreadTest
{
public class FileConvertSwf
{
//保存所有文件名
private static List<string> fileList;
//可以打印的文件格式
private List<string> printFileFormat = new List<string>() { ".doc", ".docx", ".xlsx", ".xls", ".ppt" };
public FileConvertSwf()
{
fileList = new List<string>();
}
/// <summary>
/// 将文件转化为swf文件
/// 将swf文件保存到当前目录下
/// </summary>
/// <param name="filePath">原文件路径</param>
public void ConvertToSwf(string filename)
{
//获取文件后缀名
string fileExtension = Path.GetExtension(filename);
//是否可以打印
if (fileExtension != null && printFileFormat.Contains(fileExtension.ToLower()))
{
int extensionIndex = filename.LastIndexOf(fileExtension);
//获取文件前缀名
string fileBeforeExtension = filename.Remove(extensionIndex);
//swf文件名
string targetFilename = fileBeforeExtension + ".swf";
FileInfo file = new FileInfo(targetFilename);
//不存在才转化
if (!file.Exists)
{
//使用Print2Flash3服务
IServer server = new Server();
//设置默认打印机
server.SetP2FPrinterAsDefault();
//文件转化
server.ConvertFile(@filename, @targetFilename, null, null, null);
}
}
}
/// <summary>
/// 获取某个目录下的所有文件及子目录下的所有文件
/// </summary>
/// <param name="dirPath">目录路径</param>
public void GetFilename(string dirPath)
{
//当前目录
DirectoryInfo dir = new DirectoryInfo(dirPath);
//当前目录下的所有文件
FileInfo[] files = dir.GetFiles();
foreach (var f in files)
{
//保存到文件名集合中
fileList.Add(f.FullName);
//文件转换
ConvertToSwf(f.FullName);
}
//获取当前目录下的子目录下的所有文件
DirectoryInfo[] dirs = dir.GetDirectories();
foreach (var d in dirs)
{
//递归获取文件名
GetFilename(d.FullName);
}
}
public List<string> GetFileNameList()
{
return fileList;
}
}
}
3.测试代码
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Collections.Generic;
namespace WebThreadTest
{
public partial class testGetFile : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string dirPath = Server.MapPath(@"/resource/UploadedFiles");
FileConvertSwf fcSwf = new FileConvertSwf();
fcSwf.GetFilename(dirPath);
List<string> fileList = fcSwf.GetFileNameList();
foreach (var f in fileList)
{
Response.Write(f);
Response.Write("<br />");
}
}
}
}
}
4.html页面显示swf格式
