   //using 
  System.IO;
   File.Create(%%1);

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

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

5.删除一个目录下所有的文件夹

 1 //using  2 System.IO; 3 foreach (string dirStr in Directory.GetDirectories(%%1)) 4 { 5       DirectoryInfo dir = new DirectoryInfo(dirStr); 6       ArrayList folders=new ArrayList(); 7       FileSystemInfo[] fileArr = dir.GetFileSystemInfos(); 8      for (int i = 0; i < folders.Count; i++) 9     {10          FileInfo f = folders[i] as FileInfo;11          if (f == null)12         {13              DirectoryInfo d = folders[i] as DirectoryInfo;14              d.Delete();15           }16      }17 }

6、清空文件夹
//using 
System.IO;
Directory.Delete(%%1,true);
Directory.CreateDirectory(%%1);

// Write the data to the file, byte by 
byte.
for(int i = 0; i < dataArray.Length; 
i++){
FileStream.WriteByte(dataArray[i]);
}
// Set the stream position 
to the beginning of the file.
FileStream.Seek(0, SeekOrigin.Begin);
// 
Read and verify the data.
for(int i = 0; i < FileStream.Length;

//Traditionally grep 
stands for "Global Regular Expression Print".
//Global means that an entire 
file is searched.
//Regular Expression means that a regular expression string 
is used to establish a search pattern.
//Print means that the command will 
display its findings.
//Simply put, grep searches an entire file for the 
pattern you want and displays its findings.
//
//The use syntax is 
different from the traditional Unix syntax, I prefer a syntax similar 
to
//csc, the C# compiler.
//
// grep [/h|/H] - Usage Help
//
// 
grep [/c] [/i] [/l] [/n] [/r] /E:reg_exp /F:files
//
// /c - print a count 
of matching lines for each input file;
// /i - ignore case in pattern;
// 
/l - print just files (scanning will stop on first match);
// /n - prefix 
each line of output with line number;
// /r - recursive search in 
subdirectories;
//
// /E:reg_exp - the Regular Expression used as search 
pattern. The Regular Expression can be delimited by
// quotes like "..." and 
‘...‘ if you want to include in it leading or trailing blanks;
//
// 
/F:files - the list of input files. The files can be separated by commas as in 
/F:file1,file2,file3
//and wildcards can be used for their specification as 
in /F:*file?.txt;
//
//Example:
//

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# 
code
p.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

95.报表相关
/*
using 
CrystalDecisions.CrystalReports.Engine;
using 
CrystalDecisions.Shared;
*/
2、水晶报表的两种格式
1）pull模式,不利用DataSet,直接从数据库中取出数据
2) 
push模式,使用DataSet,利用它进行数据的加载和处理等
3. 
水晶报表使用的库
1)水晶报表的引擎(CREnging.dll),作用:合并数据,装换格式
2)水晶报表设计器(CRDesigner.dll),作用：设计标题，插入数据等
3）水晶报表查看控件（CRWebFormViewer.DLL）
4)需要引入的命名空间
using 
CrystalDecisions.CrystalReports.Engine;
using 
CrystalDecisions.Shared;
4、Pull模式下使用水晶报表
1）创建rpt文件
2）拖放CrystalReportViewer
3）绑定
5、读取水晶报表文件
private 
void ReadCRV(cryatalReportViewer crv)
{
openFileDialog dlg=new 
OpenFileDialog();
dlg.Title="打开水晶报表文件";
dlg.Filter="水晶报表文件(*.rpt)|*.rpt|所有文件|*.*";
if(dlg.showDialog()==DialogResult.OK)
{
crv.ReportSource=dlg.FileName;
}
}
6. 
B/S下读取报表的文件
private void ReadCRV(cryatalReportViewer crv,File 
file)
{
string 
strName=file.PostedFile.FileName;
if(strName.Trim()!="")
{
crv.ReportSource=strName
Session["fileName"]=strName;
}
}
在B/S中要防止数据源的丢失
priavte 
void Page_Load(object sender,System.EventArgs 
e)
{
if(Session["fileName"]!=null)
{
crv.ReportSource=Session["fileName"].ToString();
}
}
7. 
假如直接从数据库中读取数据，采用PULL模式可能出现错误（登录的用户名和密码不对）
private void 
ReadCRV(CrystalReportViewer crv,CrystalReport cr)
{
ReportDocument 
reportDoc=new 
ReportDocument();
reportDoc.Load(Server.MapPath(cr));//要加载的rpt文件的名字
//解决登录的问题
TableLogOnInfo 
logonInfo = new TableLogOnInfo();
foreach(Table tb in 
ReportDoc.Database.Tables)
{
logonInfo=tb.LogOnInfo;
logonInfo.ConnectionInfo.ServerName="(loacl)";
logonInfo.ConnectionInfo.DatabaseName="Pubs";
logonInfo.ConnectionInfo.UserId="sa";
logonInfo.ConnectionInfo.Password="";
tb.ApplyLogOnInfo(logonInfo);
}
crv.ReportSource=reportDoc;
}
8. 
采用Push模式，直接在数据源读取
private void BindReport(CrystalReportViewer 
crv)
{
string 
strProvider="Server=(local);DataBase=pubs;uid=sa;pwd=";
CrystalReport cr=new 
CrystalReport();
DataSet ds=new DataSet();
SqlConnection conn=new 
SqlConnection(strProvider);
conn.open();
string strSql="select * from 
jobs";
SqlDataAdapter dap=new 
SqlDataAdapter(strSql,conn);
adp.Fill(ds,"jobs");
cr.SetDataSource(ds);
crv.ReportSource=cr;
}
9. 
导出水晶报表的文件
private void ExportCrv(CrystalReport 
cr)
{
DiskFileDestionOptions dOpt=new 
DiskFileDestionOptions();
cr.ExportOptions.ExportDestinationType=ExportDestinationType.DiskFile();
cr.ExportOptions.ExportFormatType= 
ExportFormatType.PortableDocFormat;
dOpt.DiskFileName="C:\output.pdf";
cr.ExportOptions.DestinationOptions=dOpt;
cr.Export();

}
private 
void ExportCrv(CrystalReport cr,string strType,string 
strPath)
{
DiskFileDestionOptions dOpt=new 
DiskFileDestionOptions();
cr.ExportOptions.ExportDestinationType=ExportDestinationType.DiskFile();
switch(strType)
{
case 
"RTF":
cr.ExportOptions.ExportFormatType=ExportFormatType.RichText;
dOpt.DiskFileName=strPath;
break;
case 
"PDF":
cr.ExportOptions.ExportFormatType=ExportFormatType.PortableDocFormat;
dOpt.DiskFileName=strPath;
break;
case 
"DOC":
cr.ExportOptions.ExportFormatType=ExportFormatType.WordForWindows;
dOpt.DiskFileName=strPath;
break;
case 
"XLS":
cr.ExportOptions.ExportFormatType=ExportFormatType.Excel;
dOpt.DiskFileName=strPath;
break;
default;
break;

}
cr.ExportOptions.DestinationOptions=dOpt;
cr.Export();

}
10 
B/S下水晶报表的打印
priavte void PrintCRV(CrystalReport cr)
{
string 
strPrinterName=@"printName";
PageMargins 
margins=cr.PrintOptions.PageMargins;
margins.bottomMargin = 
250;
margins.leftMargin = 350;
margins.rightMargin = 
350;
margins.topMargin = 
450;
cr.PrintOptions.ApplyPageMargins(margins);
cr.PrintOptions.printerName=strPrinterName;
cr.PrintToPrinter(1,false,0,0)//参数设置为0，表示打印所用页
