asp.net管理mysql數據庫的小工具.

    在中可以通過MySQLDatadll來操作mysql數據庫寫法跟操作SQL數據庫類似下面是相關的例子
    一打開mysql數據庫
    MySqlConnection DBConn = new MySqlConnection();
    string connString =Host=;UserName=root;PassWord=root;Database=test;Port=;CharSet=utf;Allow Zero Datetime=true;
    DBConnConnectionString = connString;
    DBConnOpen();
    二執行sql命令
    string sqlstr=select * from test;
    MySqlCommand command = new MySqlCommand(sqlstr DBConn);
    commandExecuteNonQuery();
    從上面可以看出用法跟操作SQL數據庫的SqlConnectionSqlCommand非常相似下面我這裡有一個完整的例子來實現對mysql數據庫進行管理包括浏覽表結構和數據查詢修改插入刪除數據導出數據和表結構等供大家參考和互相學習代碼寫得不規范還請大家指正
