------解决方案--------------------
string QueryStr= "select * from tablename ";
OleDbCommand Cmd = new OleDbCommand(QueryStr, myConnection);
myConnection.Open();
OleDbDataReader dr= cmd.ExecuteReader();
try
{
while (dr.Read())
{
for (int i = 0; i < dr.FieldCount; i++)
{
if (myDataReader.GetName(i) == "columnsname1 ")
{
TextBox1.Text = dr.GetString(i);
}
if (dr.GetName(i) == "columnsname2 ")
{
TextBox2.Text = dr.GetString(i);
}

}
}
catch
{
}
finally
{
dr.Close();
myConnection.Close();
}
