c#连接mysql示例代码

static void Main(string[] args)
        {
string sqlstr = "select * from manavatar";
MySQLConnection DBConn = new MySQLConnection(new MySQLConnectionString("192.168.0.13", "flashdata", "root", "root", 3306).AsString);
DBConn.Open();
//MySQLDataAdapter myadap = new MySQLDataAdapter(sqlstr, conn);
MySQLCommand DBComm = new MySQLCommand(sqlstr,DBConn);
MySQLDataReader DBReader = DBComm.ExecuteReaderEx(); //DBComm.ExecuteReaderEx();
MySQLDataAdapter DTAdapter = new MySQLDataAdapter(sqlstr,DBConn);
DataSet myDataSet = new DataSet();
DTAdapter.Fill(myDataSet,"manavatar");
try
{
while (DBReader.Read())
{
//Console.WriteLine("11");
Console.WriteLine("DBReader:{0},tttddddd:{1},tt {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。
