(急)C#用list<>向数据库添加数据

先声明一个你要添加的表实体类

public class  student

{

   public int id{getset}

   public string name{getset}

}

List<student>st=new List<student>()

foreach(var item in st)

{

    Model.student st=new Model.student()

    st.id=item.id

    st.name=itemt.name

    this.Insert(st)

}

//根据实体添加数据库

public string Insert(Model.student student)

{

.... *** 作数据库

}

可以用QueryRunner的batch方法

public class Test {

private static final String DRIVER_CLASS_NAME = ""

private static final String JDBC_URL = ""

private static final String USER = ""

private static final String PASSWORD = ""

public static void main(String[] args) {

int count = 10// 插入记录的数目

Object[][] params = new Object[count][]

for (int i = 0i <counti++)

// 将每条记录的数据插入数组

params[i] = new Object[] { "", "", "" }

batch(params)

}

public static Connection getConnection() {

Connection conn = null

try {

Class.forName(DRIVER_CLASS_NAME)

conn = DriverManager.getConnection(JDBC_URL, USER, PASSWORD)

return conn

} catch (Exception e) {

return null

}

}

public static void batch(Object[][] params) {

QueryRunner queryRunner = new QueryRunner(true)

String sql = "INSERT INTO TABLE_NAME VALUES (?,?,?)"

try {

queryRunner.batch(getConnection(), sql, params)

} catch (SQLException e) {

e.printStackTrace()

}

}

}
