Getting filesize from OpenFileDialog?

You can't directly get it from the OpenFieldDialog You need to take the file path and consturct a new FileInfo object from it like this: var fileInfo = new FileInfo(path) And from the FileInto you can get the size of the file like this fileInfo. Length For more info look at this msdn page.

I think there is 3 way, creating your custom open dialog or setting by code the view as detail or asking the user to use detail view.

If you mean when the dialog is running, I suspect you just change the file view to details. However if you mean programmatically I suspect that you'd have to hook a windows message when the file is selected.

Without interop and like the first comment, once the dialogue has been complete i.e. File/s have been selected this would give the size. Public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { if (openFileDialog1.ShowDialog() == DialogResult.

OK) { if (openFileDialog1. Multiselect) { long total = 0; foreach (string s in openFileDialog1. FileNames) total += new FileInfo(s).

Length; MessageBox. Show(total.ToString()); } else { MessageBox. Show(new FileInfo(openFileDialog1.

FileName).Length.ToString()); } } } File size during dialogue I feel would need to use interop Andrew.

Thanx for answers I want get filesize after the filedialog has been closed and show it I get file path from System.IO.Path. GetDirectoryName(op. FileName); but I can not find FILEINFo class.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
