Question

我有bool将文件添加到ListBox：

If sp.ShowDialog() = DialogResult.OK Then
    For Each wp In sp.FileNames
        ListBox1.Items.Add(wp)
    Next wp
End If

和bool将文件添加到电子邮件中：

If ListBox1.Items.Count <> 0 Then
    For Each file In ListBox1.Items
        attch = New System.Net.Mail.Attachment(file)
        message.Attachments.Add(attch)
    Next file
End If

是否可以在ListBox中仅显示文件名，但是它将包含在第二个bool中使用它的路径？

因为我使用sp.SafeFileNames时无法发送它，因为我没有路径。

您可以使用Imports System.IO Public Class Form1 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click ' add some selected files and show only their name in list Dim dialog As New OpenFileDialog If dialog.ShowDialog() <> DialogResult.OK Then Return Dim attachments = dialog.FileNames.Select(function(s) new Attachment(s)).ToArray() ListBox1.Items.AddRange(attachments) ListBox1.DisplayMember = "FileName" End Sub Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click ' do something with the attachments Dim attachments = ListBox1.Items.Cast (Of Attachment) For Each attachment In attachments Dim fullPath = attachment.FullPath Console.WriteLine(fullPath) Next End Sub End Class Public Class Attachment Public ReadOnly Property FileName As String Get Return Path.GetFileName(FullPath) End Get End Property Property FullPath As String Public Sub New(fullPath As String) Me.FullPath = fullPath End Sub End Class来展示您的商品：

#include <list>
#include <numeric>
#include <iostream>
#include <stdio.h>
#include <math.h>


using namespace std;


list<unsigned long int> primeFactors(unsigned long int n)
{
    list<unsigned long int> list;

    for (unsigned long int i=2; i <=n; i++)
    {
        while(n % i == 0)
        {
            n /= i;
            //cout << i << " ";
            list.push_back(i);
        }
        return list;
    }

}

int main()
{
    unsigned long int n;
    list<unsigned long int> plist;
    cout << "Enter num: " <<endl;
    cin>>n;
    plist = primeFactors(n);

    for(list<unsigned long int>::iterator it=plist.begin(); it != plist.end(); ++it)
    {
        cout << ' ' << *it;
        cout << '\n ';
    }


    return 0;
}

是否可以使用OpenDialog.SafeFileName发送附件？
