1、在服务器设置一个共享文件夹,在这里我的服务器ip地址是10.80.88.180,共享文件夹名字是test,test里面有两个文件:good.txt和bad.txt,访问权限,用户名是admin,密码是admin。
2、新建一个webapplication项目,在前台页面加一个listbox,ID是ListBox1.
3、添加后台代码如下:其中包含的功能是读文件,这里以读good 文件为例;写文件,这里以写bad文件为例;还有是将test文件夹下的文件名列到listbox中。
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Text; using System.Diagnostics; using System.IO; namespace WebApplication2 { public class FileShare { public FileShare() { } public static bool connectState(string path) { return connectState(path,"",""); } public static bool connectState(string path,string userName,string passWord) { bool Flag = false; Process proc = new Process(); try { proc.StartInfo.FileName = "cmd.exe"; proc.StartInfo.UseShellExecute = false; proc.StartInfo.RedirectStandardInput = true; proc.StartInfo.RedirectStandardOutput=true; proc.StartInfo.RedirectStandardError=true; proc.StartInfo.CreateNoWindow=true; proc.Start(); string dosLine = @"net use " + path + " /User:" + userName + " " + passWord + " /PERSISTENT:YES"; proc.StandardInput.WriteLine(dosLine); proc.StandardInput.WriteLine("exit"); while (!proc.HasExited) { proc.WaitForExit(1000); } string errormsg = proc.StandardError.ReadToEnd(); proc.StandardError.Close(); if (string.IsNullOrEmpty(errormsg)) { Flag = true; } else { throw new Exception(errormsg); } } catch (Exception ex) { throw ex; } finally { proc.Close(); proc.Dispose(); } return Flag; } //read file public static void ReadFiles(string path) { try { // Create an instance of StreamReader to read from a file. // The using statement also closes the StreamReader. using (StreamReader sr = new StreamReader(path)) { String line; // Read and display lines from the file until the end of // the file is reached. while ((line = sr.ReadLine()) != null) { Console.WriteLine(line); } } } catch (Exception e) { // Let the user know what went wrong. Console.WriteLine("The file could not be read:"); Console.WriteLine(e.Message); } } //write file public static void WriteFiles(string path) { try { // Create an instance of StreamWriter to write text to a file. // The using statement also closes the StreamWriter. using (StreamWriter sw = new StreamWriter(path)) { // Add some text to the file. sw.Write("This is the "); sw.WriteLine("header for the file."); sw.WriteLine("-------------------"); // Arbitrary objects can also be written to the file. sw.Write("The date is: "); sw.WriteLine(DateTime.Now); } } catch (Exception e) { // Let the user know what went wrong. Console.WriteLine("The file could not be read:"); Console.WriteLine(e.Message); } } } public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { bool status = false; //连接共享文件夹 status = FileShare.connectState(@"\\10.80.88.180\test", "admin", "admin"); if (status) { DirectoryInfo theFolder = new DirectoryInfo(@"\\10.80.88.180\test"); //先测试读文件,把目录路径与文件名连接 string filename = theFolder.ToString()+"\\good.txt"; FileShare.ReadFiles(filename); //测试写文件,拼出完整的路径 filename = theFolder.ToString() + "\\bad.txt"; FileShare.WriteFiles(filename); //遍历共享文件夹,把共享文件夹下的文件列表列到listbox foreach (FileInfo nextFile in theFolder.GetFiles()) { ListBox1.Items.Add(nextFile.Name); } } else { ListBox1.Items.Add("未能连接!"); } } } }
C#是什么
C#是一个简单、通用、面向对象的编程语言,它由微软Microsoft开发,继承了C和C++强大功能,并且去掉了一些它们的复杂特性,C#综合了VB简单的可视化操作和C++的高运行效率,以其强大的操作能力、优雅的语法风格、创新的语言特性和便捷的面向组件编程从而成为.NET开发的首选语言,但它不适用于编写时间急迫或性能非常高的代码,因为C#缺乏性能极高的应用程序所需要的关键功能。
