ListView选择ObjectDataSource数据源
ListView使用ObjectDataSource作为数据源。
一、创建解决方案，Accesss数据库文件、 类库（DAL）、Web程序。
数据库：表（User），字段（ID，Name，Sex）
类库（DAL）代码：
View Code
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; using System.Configuration; using System.Data.OleDb; namespace DAL { public class User { public static string connectionString { get { string conStr = ConfigurationManager.ConnectionStrings["study10ConnectionString"].ConnectionString; return conStr; } } public DataTable SelectMethod() { using (OleDbConnection conn = new OleDbConnection(connectionString)) { OleDbDataAdapter oda = new OleDbDataAdapter(); OleDbCommand comm = conn.CreateCommand(); comm.CommandType = CommandType.Text; comm.CommandText = "SELECT [ID],[Name],[Sex] FROM [User]"; oda.SelectCommand = comm; DataTable dt = new DataTable(); oda.Fill(dt); return dt; } } public int DeleteMethod(int ID) { using (OleDbConnection conn = new OleDbConnection(connectionString)) { conn.Open(); OleDbCommand comm = conn.CreateCommand(); comm.CommandType = CommandType.Text; comm.CommandText = "DELETE FROM [User] WHERE [ID]=@id"; comm.Parameters.Add(new OleDbParameter("@id",ID)); return comm.ExecuteNonQuery(); } } public int UpdataMethod(string name, string sex, int ID) { using (OleDbConnection conn = new OleDbConnection(connectionString)) { conn.Open(); OleDbCommand comm = conn.CreateCommand(); comm.CommandType = CommandType.Text; comm.CommandText = "UPDATE [User] SET [Name]=@name,[Sex]=@sex WHERE [ID]=@id"; comm.Parameters.Add(new OleDbParameter("@name", name)); comm.Parameters.Add(new OleDbParameter("@sex", sex)); comm.Parameters.Add(new OleDbParameter("@id", ID)); return comm.ExecuteNonQuery(); } } public int InsertMethod(string name, string sex) { using (OleDbConnection conn = new OleDbConnection(connectionString)) { conn.Open(); OleDbCommand comm = conn.CreateCommand(); comm.CommandType = CommandType.Text; comm.CommandText = "INSERT INTO [User] ([Name],[Sex]) VALUES(@name,@sex)"; comm.Parameters.Add(new OleDbParameter("@name", name)); comm.Parameters.Add(new OleDbParameter("@sex", sex)); return comm.ExecuteNonQuery(); } } } }
Web程序:
配置文件添加connectionStrings节点：
View Code
<?xml version="1.0"?> <!-- 有关如何配置 ASP.NET 应用程序的详细信息，请访问 http://go.microsoft.com/fwlink/?LinkId=169433 --> <configuration> <connectionStrings> <add name="ConnectionString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\study10.accdb;Persist Security Info=True" providerName="System.Data.OleDb" /> </connectionStrings> <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> </configuration>
数据库放在App_Data文件夹中。
ObjectDataSource-TypeName属性=执行数据操作的对象类型（类名)
数据源手动配置就可以了(选择相对应的方法)，代码会自动生成。图
Default.aspx代码：

注意：ListView——首先设置DataKeyNames（ID）用于Delete,Update传递参数。Update,Insert方法需要传递参数来更新，Name，Sex字段用Bind绑定(双向)
