新手求助 C#链接access哪里出错了
点击按钮后和卡死一样没反应，代码如下
private void Button_Click_1(object sender, RoutedEventArgs e)
{
string dir = Directory.GetCurrentDirectory();
string strcon="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + "\\db.mdb";
using (OleDbConnection con = new OleDbConnection(strcon))
{
if (con.State != ConnectionState.Open)
{
con.Open();
}
DataSet ds = new DataSet();
OleDbDataAdapter oda = new OleDbDataAdapter("select * from userinfo",con);
oda.Fill(ds);
DataTable table = ds.Tables[0];
DataRowCollection rows=table.Rows;
for(int i=0;i<rows.Count;i++){
DataRow row = rows[i];
string username = (string)row["username"];
MessageBox.Show(username);
}
}
}
