c 操作MySql資料庫

需要mysql.data.dll

資料庫連線

//server資料庫位址，user資料庫使用者名稱，password密碼，database資料庫名

string connectstring = string.format("server=;user id=;password=;database=;", server, user, password, database);
mysqlconnection conn = new mysqlconnection(connectstring );
conn.open();
//加資料庫操作
conn.close();
conn.dispose();

mysqlcommand command = conn.createcommand();

string str = "insert into (id,name)values('','')";
//表名，欄位id的值，欄位name的值
command.commandtext = string.format(str, table, id, name);
command.executenonquery();

mysqlcommand command = conn.createcommand();

string str = string.format("delete from  where id=''", table, idnumber);
command.commandtext = str;
command.executenonquery();

mysqlcommand command = conn.createcommand();

string str = "update  set id='',name=''"
;command.commandtext = string.format(str, table, id, name);
command.executenonquery();

mysqlcommand command = conn.createcommand();

string str = string.format("truncate table ", table);
command.commandtext = str;
command.executenonquery();

string command = string.format("select * from ", 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++)
