需要mysql.data.dll
資料庫連線

//server資料庫地址，user資料庫使用者名稱，password密碼，database資料庫名
string ConnectString = string.Format("Server={0};User ID={1};Password={2};Database={3};", server, user, password, database);
MySqlConnection conn = new MySqlConnection(ConnectString );
conn.Open();
//加資料庫操作
conn.Close();
conn.Dispose();
 

新增

MySqlCommand command = conn.CreateCommand();
string str = "INSERT INTO {0}(id,name)VALUES('{1}','{2}')";
//{0}表名，{1}欄位id的值，{2}欄位name的值
command.CommandText = string.Format(str, table, ID, Name);
command.ExecuteNonQuery();

刪除

MySqlCommand command = conn.CreateCommand();
string str = string.Format
 
("DELETE FROM {0} WHERE id='{1}'", table, IdNumber);
command.CommandText = str;
command.ExecuteNonQuery();

修改

MySqlCommand command = conn.CreateCommand();
string str = "UPDATE {0} SET id='{1}',name='{2}'";
command.CommandText = string.Format(str, table, Id, Name);
command.ExecuteNonQuery();

清空表

MySqlCommand command = conn.CreateCommand
 
();
string str = string.Format("truncate table {0}", table);
command.CommandText = str;
command.ExecuteNonQuery();

查詢

string command = string.Format("SELECT * FROM {0}", table);//
MySqlCommand mycmd = new MySqlCommand(command, conn);
MySqlDataAdapter adapter = new MySqlDataAdapter(mycmd);
DataSet ds = new DataSet();
adapter.Fill(ds);
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
    string id = ds.Tables[0].Rows[i][0].ToString();
    string name = ds.Tables[0].Rows[i][1].ToString();
}
