如何将datetimepicker与getfile一起使用

Question

        string Date1 = dateTimePicker1.Value.ToString("ddMM");

    foreach (string file in Directory.GetFiles(@"C:\tbank_file\out\", "*.txt"))
    {
        MessageBox.Show(file);
    }

我想在getfile的循环foreach中使用变量date1

Answer 1

 string Date1 = dateTimePicker1.Value.ToString("ddMM");

    foreach (string file in Directory.GetFiles(@"C:\tbank_file\out\", "*.txt"))
    {
        MessageBox.Show(file+" "+ Date1);
    }

Answer 2

foreach (string file in Directory.GetFiles(@"C:\tbank_file\out\", "*.txt"))
    {
        MessageBox.Show(file+" "+ dateTimePicker1.Value.ToString("dd/MM/yyyy"););
    }
