Question

I am thinking that this is big problem ….

I have path like this…”C:\restore\restoredb\”

In that path i have files like this..

 restore-2011-10-12T17-16-51.zip
 restore-2011-10-11T13-24-45.zip
 restore-2011-05-11T09-45-56.zip
 restore-2011-08-11T09-08-07.zip
 restore-2010-09-11T09-45-12.zip 

I have a form , in that form i have a listbox and combobox(cbrestore)
I have got the combobox items like this …Month, 3 months,6 months,year…

what i want is , if i select the combobox item(month) i want to display the file names which are stored in that folder between these dates (12-10-2011 to 12-09-2011)..

If i select combobox item(3 months) i want to display the file names which are stored in that folder between these dates (12-10-2011 to 12-07-2011)..in listbox

For that i have tried this ….

 private void cbrestore_SelectedIndexChanged(object sender, EventArgs e)
 {
    string fullpathforfiles = @"C:\restore\restoredb\";
    string[] allfiles = Directory.GetFiles(fullpathforfiles);
    foreach (string single in allfiles)
    {
        string filenameonly = Path.GetFileName(single);     
    }
    if (cbrestore.SelectedValue == Daterange.type1)
    { 

    } 
}
struct Daterange 
{
    public const string type1 = "Month";
    public const string type2 = "3 Months";
    public const string type3 = "6 Months";
    public const string type4 = "Year";  

}

I dont know how to extract the exact part in that filename and adding that …
any idea how can i do this .. pls ..

Any suggestions and any code sample snippet would be very greatful to me ….

Many thanks…..

Answer 1

I’d do it like this:

    private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        List<String> t = Directory.GetFiles(@"C:\Users\justin\Desktop\New folder (2)").ToList();
        List<String> y = new List<string>();
        List<String> u = new List<string>();
        foreach (var zzz in t)
        {
            y.Add(Path.GetFileName(zzz));
        }


        if (comboBox1.Text == "Month")
        {
            u =
           (from String s in y where ((DateTime.Now.Month - DateTime.Parse(s.Substring(8, 10)).Month) < 1) && (DateTime.Now.Year - DateTime.Parse(s.Substring(8, 10)).Year == 0) select s).
               ToList();
        }
        else if (comboBox1.Text == "3 Month")
        {
            u =
           (from String s in y where ((DateTime.Now.Month - DateTime.Parse(s.Substring(8, 10)).Month) < 3) && (DateTime.Now.Year - DateTime.Parse(s.Substring(8, 10)).Year == 0) select s).
               ToList();
        }
        else if(comboBox1.Text == "1 Year")
        {
            u =
           (from String s in y where ((DateTime.Now.Month - DateTime.Parse(s.Substring(8, 10)).Month) < 12) select s).
               ToList();
        }
        
        listBox1.DataSource = u;

    }

The Result is this :

EDIT: Fixed the month problem select you see in the SS and added the year select.
