一 、界面简单设计如下：
二 、代码如下：

三、用到的自定义类AccessDAO：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; using System.Data.OleDb; using System.Data.SqlClient; using System.Text.RegularExpressions; //正则表达式引用所需 namespace Data1 { //access的数据访问接口 class AccessDAO { public static class Property { public static string accessFilePath = "d:\nCTDCBJYQ04DataSet.mdb"; //若放入主程序，则可如下设置 //one mainFrm = (one)this.Owner; //string prjName = mainFrm.laPrj.Text; //string prjPath = mainFrm.laFile_Path.Text; // public static string accessFilePath = prjPath + "\矢量数据\" + prjName + ".mdb"; } //从access数据库获取数据 //dataFilePath指定access文件的路径 //sql指定数据库的查询语句 //DataSet为查询返回的数据集 public static DataSet getDataSetFromAccessTable(string sql, string dataFilePath) { // 连接数据库 OleDbConnection connct = new OleDbConnection(); string oleDB = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dataFilePath; connct.ConnectionString = oleDB; //创建命令 OleDbCommand command = new OleDbCommand(sql, connct); //打开数据库 connct.Open(); //执行命令 DataSet dataSet = new DataSet(); OleDbDataAdapter dataAdapter = new OleDbDataAdapter(command); dataAdapter.Fill(dataSet); // 关闭连接 connct.Close(); return dataSet; } //更新或者插入数据到access数据库 //dataFilePath指定access文件的路径 //sql指定数据库的更新或者插入语句 //返回值int表示此次更新影响的行数 public static int updateAccessTable(string sql, string dataFilePath) { // 连接数据库 OleDbConnection connct = new OleDbConnection(); string oleDB = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dataFilePath; connct.ConnectionString = oleDB; //打开数据库 connct.Open(); //执行命令 OleDbCommand myCommand = new OleDbCommand(sql, connct); int res = myCommand.ExecuteNonQuery(); // 关闭连接 connct.Close(); return res; } //更新或者插入数据到access数据库 //dataFilePath指定access文件的路径 //command指定操作（更新或者插入）数据库的命令 //返回值int表示此次更新影响的行数 public static int updateAccessTable(OleDbCommand command, string dataFilePath) { // 连接数据库 OleDbConnection connct = new OleDbConnection(); string oleDB = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dataFilePath; connct.ConnectionString = oleDB; //打开数据库 connct.Open(); //执行命令 //OleDbCommand myCommand = new OleDbCommand(sql, connct); command.Connection = connct; int res = command.ExecuteNonQuery(); // 关闭连接 connct.Close(); return res; } public bool ckDigital_Num(string digitalItem, int digitalNum) //正则检查是否为数字,且位数一定 { bool isDigital_Num = false; Regex reGen = new Regex(@"^d{" + digitalNum.ToString("F0") + "}$"); //正则表达式,n位数字 if (reGen.IsMatch(digitalItem)) isDigital_Num = true; return isDigital_Num; } } }
