后台代码：
public ActionResult loadFileInfo() { StringBuilder sb = new StringBuilder(); DirectoryInfo theFolder = new DirectoryInfo(Server.MapPath("~/UploadFile/")); DirectoryInfo[] dirInfo = theFolder.GetDirectories(); //遍历文件夹 foreach (DirectoryInfo NextFolder in dirInfo) { FileInfo[] fileInfo = NextFolder.GetFiles(); //遍历文件 foreach (FileInfo NextFile in fileInfo) { string exStr = NextFile.Extension; string str = NextFile.Name; if (exStr == ".zip" || exStr == ".7z" || exStr == ".rar" || exStr.ToLower() == ".rars") { sb.Append("" + str + "
"); } else if (exStr == ".doc" || exStr == ".docx") { sb.Append("" + str + "
"); } else if (exStr == ".ppt" || exStr == ".pptx") { sb.Append("" + str + "
