{
string sqlstr = "select * from manavatar";
MySQL(和PHP搭配之最佳组合)Connection DBConn = new MySQL(和PHP搭配之最佳组合)Connection(new MySQL(和PHP搭配之最佳组合)ConnectionString("192.168.0.13", "flashdata", "root", "root", 3306).AsString);
DBConn.Open();
//MySQL(和PHP搭配之最佳组合)DataAdapter myadap = new MySQL(和PHP搭配之最佳组合)DataAdapter(sqlstr, conn);
MySQL(和PHP搭配之最佳组合)Command DBComm = new MySQL(和PHP搭配之最佳组合)Command(sqlstr,DBConn);
MySQL(和PHP搭配之最佳组合)DataReader DBReader = DBComm.ExecuteReaderEx(); //DBComm.ExecuteReaderEx();
MySQL(和PHP搭配之最佳组合)DataAdapter DTAdapter = new MySQL(和PHP搭配之最佳组合)DataAdapter(sqlstr,DBConn);
DataSet myDataSet = new DataSet();
DTAdapter.Fill(myDataSet,"manavatar");
try
{
while (DBReader.Read())
{
//Console.WriteLine("11");
Console.WriteLine("DBReader:{0},\t\t\tddddd:{1},\t\t {2}",DBReader.GetString(0), DBReader.GetString(1),DBReader.GetString(3));
}
Console.WriteLine("0000");
}
catch (Exception e)
{
Console.WriteLine("读入失败!"+e.ToString());
}
finally
{
Console.WriteLine("DBReader关闭");
Console.WriteLine("DBConn关闭");
DBReader.Close();
//DBConn.Close();
}
for (int i = 0; i < myDataSet.Tables["manavatar"].Rows.Count; i++)
{
Console.WriteLine("{0}",myDataSet.Tables["manavatar"].Rows[2]["user"]);
}
}
这是一个简单的例子。
在这里有个问题:dataset如果没设主键的话,可能会引起一些对数库操作的问题,比如会造成updata出现错误。
