访问c＃中的pdf文件属性

问题描述

我开发了winform应用程序，用于访问pdf属性，如文件名和完整路径



文件，大小，扩展名，pdf file.alredy的内容我正在访问路径的文件和内容



的pdf文件然后我想要重新属性文件名，大小，扩展名





重要提示：文件类对于fileinfoarray非常有用，但我没有使用fileinfo数组i



我只使用字符串数组。不是告诉我们使用File class.it对filname，size，extensions没用。文件类没有访问扩展名，文件名，大小的方法。如果没有方法，那么



接近将在那里告诉我。

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        public static string ExtractTextFromPdf(string filename)
        {
            using (PdfReader r = new PdfReader(filename))
            {
                StringBuilder text = new StringBuilder();

                for (int i = 1; i <= r.NumberOfPages; i++)
                {
                    text.Append(PdfTextExtractor.GetTextFromPage(r, i));

    class fileatt
    {
        public long FileSize { get; set; }
        public string fName { get; set; }
        public string fFullName { get; set; }
        public string fExtension { get; set; }
        public string fContent { get; set; }
    }
}
