Access新建了一个名为user的数据库，其中有张名为UserInfor的表。将之添入项目中后，访问数据表中数据。这样做：
OleDbConnection mycon =
null;
OleDbDataReader myReader =
null;
string str =
"";
try
{
string strcon =
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=user.mdb;";
mycon =
new OleDbConnection(strcon);
mycon.Open();
string sql =
"SELECT * FROM UserInfor";
OleDbCommand mycom =
new OleDbCommand(sql, mycon);
myReader = mycom.ExecuteReader();
while (myReader.Read())
{
str += myReader.GetString(
0) +
" " + myReader.GetString(
1);
}
MessageBox.Show(str);
}
finally
{
myReader.Close();
mycon.Close();
}
