Question

User2045693258 posted

I'm looping trhough some files in a folder, is there any way to arrange them by filename alphabetically?

here is what i have so far

Dim diFiles As DirectoryInfo = New DirectoryInfo(Server.MapPath(mypath))
Dim aryFi As IO.FileInfo() = diFiles.GetFiles("*")
Dim fi As IO.FileInfo
For Each fi In aryFi

Next

Does this work:

For Each fi In aryFi.OrderBy(Function(s) s.FullName) 
Next

 no, is that some c# you've converted?

 

orderby isn't a member of system.array

It's an extension method with a lambda expression.  Are you using .net Framework 3.5?

One idea I thought of is copying the results into a List<string> (possibly using AddRange) and using the list's Sort method.

Dude here is your code

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Collections;
using System.IO;

/// <summary>
/// Summary description for CompareFiles
/// </summary>
public class CompareFiles:IComparer
{
	public CompareFiles()
	{
		
	}

    #region IComparer Members

    public int Compare(object x, object y)
    {
        int result = 0;
        if((x is FileInfo) && (y is FileInfo))
        {
            FileInfo X = (FileInfo)x;
            FileInfo Y = (FileInfo)y;

            result = X.Name.CompareTo(Y.Name);
        }
        return result;
    }

    #endregion
}

// In your Asp.net Page

       CompareFiles compareFiles = new CompareFiles();
        
        DirectoryInfo D = new DirectoryInfo(@"D:\\SHAREDLOCATIONIMAGES");
        FileInfo[] filesInfo =  D.GetFiles();
        ArrayList arl = new ArrayList(filesInfo);
        arl.Sort(compareFiles);
