C# 向共享文件中寫入數據

   先寫一個判斷此時是否可以正常連接網絡共享主機：

private static bool connectState()
        {
            bool flag = false;
            Process process = new Process();
            try
            {
                process.StartInfo.FileName = "cmd.exe";
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.RedirectStandardInput = true;
                process.StartInfo.RedirectStandardOutput = true;
                process.StartInfo.RedirectStandardError = true;
                process.StartInfo.CreateNoWindow = true;
                process.Start();
                string dosLine = @"net use \\IP_ADDRESS\PATH /User:username password /PERSISTENT:YES";
                process.StandardInput.WriteLine(dosLine);
                process.StandardInput.WriteLine("exit");
                while (!process.HasExited)
                {
                    process.WaitForExit(1000);
                }
                string errorMsg = process.StandardError.ReadToEnd();
                process.StandardError.Close();
                if (String.IsNullOrEmpty(errorMsg))
                {
                    flag = true;
                }
                else
                {
                    throw new Exception(errorMsg);
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                process.Close();
                process.Dispose();
            }
            return flag;
        }

   當然這一段就是訪問網絡文件的核心了，之后就是正常的操作文件了（僅限局域網）我的是這樣子的，很簡單的一個：

public static void logs(string str)
        {
            using (FileStream fs = new FileStream("http://IP_ADDRESS/PATH/hook.txt", FileMode.Append, FileAccess.Write))
            {
                using (StreamWriter sw = new StreamWriter(fs))
                {
                    sw.WriteLine(str);
                }
            }
        }
