C# print2flash3文件转化
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
