finding all file sizes in a directory in c#

Question

I have a string array with different file names (with path) and I want to find out the size of each one. How can I find the size of each file using C#?

Please suggest!!

Answer 1

Bytes:

For Each item As String In filelist
MsgBox("File Size(Bytes) for " + item + ": "+My.Computer.FileSystem.GetFileInfo(item).Length.ToString)
Next

Kilobytes:

For Each item As String In filelist
Dim blen As Integer = +My.Computer.FileSystem.GetFileInfo(item).Length
Dim len As Integer = 0
Dim donext As Boolean = True
If blen <= 1024 Then
donext = False
End If
While donext = True
blen -= 1024
len += 1
If blen <= 1024 Then
donext = False
End If
End While
MsgBox("File Size(Kilobytes) for " + item + ": "+len.ToString)
Next

If you want it in C#, Google "Convert VB.NET to C#".

Also, Replace filelist in the For statements as the list in which the file paths are.

You can directly use this:

System.IO.FileInfo f = new FileInfo("aaa.txt"); 
Console.WriteLine(f.Length.ToString());

May this code snippet also give some ideas to your requirement:
Converted from the VB code of maxter.
See the Code Converter here:http://www.carlosag.net/Tools/CodeTranslator/.

   foreach (string item in filelist)

   {

    ((int)(blen)) = My.Computer.FileSystem.GetFileInfo(item).Length;

    int len = 0;

    bool donext = true;

    if ((blen <= 1024))

    {

     donext = false;

    }

    while ((donext == true))

    {

     blen -= 1024;

     len++;

     if ((blen <= 1024))

     {

      donext = false;

     }

    }

    MsgBox(("File Size(Kilobytes) for "

     + (item + (": " + len.ToString))));

   }
