  • C#读写共享文件夹

    该试验分以下步骤:

    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。

                //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!");
                }
            }
        }

    按以上步骤,即可实现读写网络共享文件。
