如何在MySQL中使用ADO.NET DbProviderFactory？

Answer 1

首先,您必须安装MySQL .Net Connector.

MySQL Provider工厂具有不变名称"MySql.Data.MySqlClient".下面是一些示例C#代码,它检索本地测试数据库中的所有表名,并将它们放在列表框中以响应按钮单击.

private void button1_Click(object sender, EventArgs e)
{
    var dbf = DbProviderFactories.GetFactory("MySql.Data.MySqlClient");
    using (var dbcn = dbf.CreateConnection())
    {
        dbcn.ConnectionString = "Server=localhost;Database=test;Uid=test;Pwd=test;";
        dbcn.Open();
        using (var dbcmd = dbcn.CreateCommand())
        {
            dbcmd.CommandType = CommandType.Text;
            dbcmd.CommandText = "SHOW TABLES;";
            using (var dbrdr = dbcmd.ExecuteReader())
            {
                while (dbrdr.Read())
                {
                    listBox1.Items.Add(dbrdr[0]);
                }
            }
        }
    }
}
