WinForm 中添加 openFileDialog Button, WinForm .cs 中添加本地.mdf,如下：
using System;using System.Collections.Generic;using System.Linq;using System.Windows.Forms;namespace txt记事本文件的读写{static class Program{/// <summary>/// 应用程序的主入口点。/// </summary> [STAThread]static void Main(){//SQLServer 附加mdf文件string dataDir = AppDomain.CurrentDomain.BaseDirectory;if (dataDir.EndsWith(@"\bin\Debug\") || dataDir.EndsWith(@"\bin\Release\")){dataDir = System.IO.Directory.GetParent(dataDir).Parent.Parent.FullName;AppDomain.CurrentDomain.SetData("DataDirectory", dataDir);}Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);Application.Run(new Form1());}}}
读取txt中的数据写入DB：
using System;using System.Collections.Generic;using ponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.Data.SqlClient;using System.IO;namespace txt记事本文件的读写{public partial class Form1 : Form{public Form1(){InitializeComponent();}private void BtnReadTXT_Click(object sender, EventArgs e){if (odfImport.ShowDialog() == DialogResult.OK){using (SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\TelphoneNo.mdf;Integrated Security=True;User Instance=True")){conn.Open();using (FileStream fileStream = File.OpenRead(odfImport.FileName)) //打开txt文件{using (StreamReader stmReader = new StreamReader(fileStream)) //读取txt文件 {string line = null;string TelNo = "";string Name = "";string strIns = "";//sql 参数strIns = "insert into PhoneNo(TelNO,Name) values(@telNO,@name) ";SqlParameter[] sqlPara = new SqlParameter[] { new SqlParameter("telNO",TelNo),new SqlParameter("name",Name)};//把读取出来的数据写入.mdfusing (SqlCommand sqlCmd = new SqlCommand(strIns, conn)){//逐行读取while ((line = stmReader.ReadLine()) != null){string[] strTel = line.Split('-');TelNo = strTel[0].ToString();Name = strTel[1].ToString();sqlCmd.Parameters.AddRange(sqlPara);sqlCmd.ExecuteNonQuery();sqlCmd.Parameters.Clear(); //参数清除 }MessageBox.Show("导入成功", "Read TXT");}}}}}else{return;}}}}
