c# 获取文件最后修改日期代码
FileInfo f = new FileInfo(@"c:\1.txt");
Console.WriteLine(f.LastWriteTime.ToString());
c# 获取文件最后访问时间代码
FileInfo f = new FileInfo(@"c:\1.txt");
Console.WriteLine(f.LastAccessTime.ToString());//最后访问
c# 获取文件创建时间代码
FileInfo f = new FileInfo(@"c:\1.txt");
Console.WriteLine(f.CreationTime.ToString());
c# 获取文件大小代码
FileInfo f = new FileInfo(@"c:\1.txt");
Console.WriteLine(f.Length.ToString());
c# 获取文件文件属性代码
FileInfo f = new FileInfo(@"c:\1.txt");
Console.WriteLine(f.Attributes);

C#文件路径

 

 FileInfo f = new FileInfo(@"c:\1.txt");
Console.WriteLine(f.DirectoryName);
 
 C#追加文件
    StreamWriter sw = File.AppendText(Server.MapPath(".")+"\\myText.txt");
    sw.WriteLine("追逐理想");
    sw.WriteLine("kzlll");
    sw.WriteLine(".NET笔记");
    sw.Flush();
    sw.Close();
C#拷贝文件
    string OrignFile,NewFile;
    OrignFile = Server.MapPath(".")+"\\myText.txt";
    NewFile = Server.MapPath(".")+"\\myTextCopy.txt";
    File.Copy(OrignFile,NewFile,true);
C#删除文件
    string delFile = Server.MapPath(".")+"\\myTextCopy.txt";
    File.Delete(delFile);
C#移动文件
    string OrignFile,NewFile;
    OrignFile = Server.MapPath(".")+"\\myText.txt";
    NewFile = Server.MapPath(".")+"\\myTextCopy.txt";
    File.Move(OrignFile,NewFile);
 
 
讲文件从一个目录复制到另一个目录
 FileInfo fi = new FileInfo(path1);
fi.CopyTo(path2, true);
