一 、界面簡單設計如下：
二 、代碼如下：

三、用到的自定義類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; //正則表達式引用所需 namespace Data1 { //access的數據訪問接口 class AccessDAO { public static class Property { public static string accessFilePath = "d:\\nCTDCBJYQ04DataSet.mdb"; //若放入主程序，則可如下設置 //one mainFrm = (one)this.Owner; //string prjName = mainFrm.laPrj.Text; //string prjPath = mainFrm.laFile_Path.Text; // public static string accessFilePath = prjPath + "\\矢量數據\\" + prjName + ".mdb"; } //從access數據庫獲取數據 //dataFilePath指定access文件的路徑 //sql指定數據庫的查詢語句 //DataSet為查詢返回的數據集 public static DataSet getDataSetFromAccessTable(string sql, string dataFilePath) { // 連接數據庫 OleDbConnection connct = new OleDbConnection(); string oleDB = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dataFilePath; connct.ConnectionString = oleDB; //創建命令 OleDbCommand command = new OleDbCommand(sql, connct); //打開數據庫 connct.Open(); //執行命令 DataSet dataSet = new DataSet(); OleDbDataAdapter dataAdapter = new OleDbDataAdapter(command); dataAdapter.Fill(dataSet); // 關閉連接 connct.Close(); return dataSet; } //更新或者插入數據到access數據庫 //dataFilePath指定access文件的路徑 //sql指定數據庫的更新或者插入語句 //返回值int表示此次更新影響的行數 public static int updateAccessTable(string sql, string dataFilePath) { // 連接數據庫 OleDbConnection connct = new OleDbConnection(); string oleDB = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dataFilePath; connct.ConnectionString = oleDB; //打開數據庫 connct.Open(); //執行命令 OleDbCommand myCommand = new OleDbCommand(sql, connct); int res = myCommand.ExecuteNonQuery(); // 關閉連接 connct.Close(); return res; } //更新或者插入數據到access數據庫 //dataFilePath指定access文件的路徑 //command指定操作（更新或者插入）數據庫的命令 //返回值int表示此次更新影響的行數 public static int updateAccessTable(OleDbCommand command, string dataFilePath) { // 連接數據庫 OleDbConnection connct = new OleDbConnection(); string oleDB = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dataFilePath; connct.ConnectionString = oleDB; //打開數據庫 connct.Open(); //執行命令 //OleDbCommand myCommand = new OleDbCommand(sql, connct); command.Connection = connct; int res = command.ExecuteNonQuery(); // 關閉連接 connct.Close(); return res; } public bool ckDigital_Num(string digitalItem, int digitalNum) //正則檢查是否為數字,且位數一定 { bool isDigital_Num = false; Regex reGen = new Regex(@"^\d{" + digitalNum.ToString("F0") + "}$"); //正則表達式,n位數字 if (reGen.IsMatch(digitalItem)) isDigital_Num = true; return isDigital_Num; } } }
