1.创建文件夹//using System.IO;Directory.CreateDirectory(%%1);

2.创建文件//using System.IO;File.Create(%%1);

3.删除文件//using System.IO;File.Delete(%%1);

4.删除文件夹//using System.IO;Directory.Delete(%%1);

90.提取PDF文件中的文本xpdf public partial class Form1 : Form { public OpenFileDialog ofdlg = new OpenFileDialog();//打开文件对话框 public string filename;

public Form1() { InitializeComponent(); }

private void button1_Click(object sender, EventArgs e) { ofdlg.Filter = "pdf文件(*.pdf)|*.pdf";//选择pdf文件 if (ofdlg.ShowDialog() == DialogResult.OK) { filename = string.Format("{0}", ofdlg.FileName); } }　　　　　　//传送打开文件对话框中得到的filename来做为外部程序的参数来做转化 private void button2_Click(object sender, EventArgs e) { Process p = new Process(); string path = "pdftotext.exe"; //进程启用外部程序 　　　　　　　　　　　　　　　　//这个exe我放在debug文件夹下面 p.StartInfo.FileName = path; p.StartInfo.Arguments = string.Format( filename + " -");//很怪异的一行 　　　　　　　　　　　　　　　　　　　　　　　//参数“－”表示可以得到输出流 p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardInput = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.CreateNoWindow = true; p.Start(); string s = p.StandardOutput.ReadToEnd();//得到pdf文档中的文本内容 textBox1.Text = s; p.Close(); } }}

上面的程序运行后，如果是在Debug文件夹下的pdf文件就可以得到输出，可是如果在打开文件对话框中打开我桌面上的一个pdf如：@"d:\我的文档\test.pdf"，输出就会是空，但是如果把上面那怪异的一行改为： C# codep.StartInfo.Arguments = string.Format( @"d:\我的文档\test.pdf" + " -");

程序就又会得到输出。 呵呵，谢谢楼上的兄台，下载的xpdf中xpdftotext.exe用到的配置文件xpdfrc需要手动配置，我如果把那些字体啊，什么的映射成绝对路径下的文件，就不会出现上面的问题，但是我把配置文件中的路径改成了相对路径，于是就出现了上面的问题了，看兄台能够很轻易的就运行成功，一定是做过很多代码的，这里还得劳烦兄台再给看一下，帮下忙，能遇到一个大神不容易，大神可不能吝啬啊，先谢过了哈
