directoryinfoDirectory.GetFiles访问权限

FileInfo [] files = (new DirectoryInfo(path)).GetFiles(); 请问这是什么意思

path:填写你要找的文件所在文件夹就可以 FileInfo[] files = new DirectoryInfo(@"D:aa").GetFiles();//获取D盘aa文件夹下的所有文件（不包括里面的目录） string aa = ""; foreach (FileInfo file in files)//遍历文件 { if(file.Name=="A") aa += file.Name + "" + file.Length+";";//file.Length文件大小,file.Name文件名 } MessageBox.Show(aa);//显示

Directory(DirectoryInfo)类及File(FileInfo)类的使用方法

DirectoryInfo使用方法 using System; using System.IO; class Test { publicstaticvoid Main() { // Specify the directories you want to manipulate. DirectoryInfo di = new DirectoryInfo(@"c:MyDir"); try { // Determine whether the directory exists.if (di.Exists) { // Indicate that the directory already exists. Console.WriteLine("That path exists already."); return; } // Try to create the directory. di.Create(); Console.WriteLine("The directory was created essfully."); // Delete the directory. di.Delete(); Console.WriteLine("The directory was deleted essfully."); } catch (Exception e) { Console.WriteLine("The process failed: {0}", e.ToString()); } finally {} } } FileInfo使用方法: sing System; using System.IO; class Test { publicstaticvoid Main() { string path = Path.GetTempFileName(); FileInfo fi1 = new FileInfo(path); //Create a file to write to.using (StreamWriter sw = fi1.CreateText()) { sw.WriteLine("Hello"); sw.WriteLine("And"); sw.WriteLine("e"); } //Open the file to read from.using (StreamReader sr = fi1.OpenText()) { string s = ""; while ((s = sr.ReadLine()) != null) { Console.WriteLine(s); } } try { string path2 = Path.GetTempFileName(); FileInfo fi2 = new FileInfo(path2); //Ensure that the target does not exist. fi2.Delete(); //Copy the file. fi1.CopyTo(path2); Console.WriteLine("{0} was copied to {1}.", path, path2); //Delete the newly created file. fi2.Delete(); Console.WriteLine("{0} was essfully deleted.", path2); } catch (Exception e) { Console.WriteLine("The process failed: {0}", e.ToString()); } } }

只获取某个目录下面的文件，不获取子目录下面的文件，c#，DirectoryInfo(),如何使用

try { DirectoryInfo dirInfo = new DirectoryInfo("你的文件夹路径"); FileInfo[] fileInfos = dirInfo.GetFiles("*", SearchOption.TopDirectoryOnly); foreach (FileInfo fInfo in fileInfos) { // 你想干的事情 } } catch (System.Exception) { }

Directory.GetFiles方法如何使用变量

private List<FileInfo> GetPath(string strDir) { List<FileInfo> list = new List<FileInfo>(); DirectoryInfo d = new DirectoryInfo(strDir);//图片目录 FileInfo[] fs = null; fs = d.GetFiles("*.jpg"); list.AddRange(fs); fs = d.GetFiles("*.gif"); list.AddRange(fs); fs = d.GetFiles("*.txt"); list.AddRange(fs); fs = d.GetFiles("*.doc"); list.AddRange(fs); return list; }

Directory.GetFiles访问权限

web应用程序当然没这个权限，要访问磁盘该用winform就没问题了 你说你能访问C盘，我是不相信的，web程序只能访问根目录下的东西 但你的错误并非访问d盘造成的System.IO.Directory.GetFiles("d:/"); 这句代码不会抛出异常 请把 改成 在运行，会报出详细错误位置
