我对这件事很陌生。其实这是我的第一部作品。我想要一个从文本框中读取随机文件计数的程序。它有一个按钮可以从选定的路径随机化文件。我需要在列表框中打开文件。
我的问题是当我双击列表框时,无论我点击什么文件,它都会打开列表中的最后一个文件。我试图在下面添加两个斜杠的行。但它也没有奏效。我能做些什么?
public Form1()
{
InitializeComponent();
}
Random r = new Random();
string path1;
DirectoryInfo dif;
FileInfo[] files;
int randomchoose;
//FileInfo[] files2;
//int hoho;
int[] randomcount;
private void button1_Click(object sender, EventArgs e)
{
FolderBrowserDialog hoho = new FolderBrowserDialog();
hoho.ShowNewFolderButton = true;
if (hoho.ShowDialog() == DialogResult.OK)
{
path1 = hoho.SelectedPath;
textBox1.Text = path1;
dif = new DirectoryInfo(path1);
files = dif.GetFiles();
}
}
private void btnrasgele_Click(object sender, EventArgs e)
{
randomcount = new int[Convert.ToInt32(textBox3.Text)];
// int hoho=0;
foreach (int k in randomcount)
{
int pd = files.Length;
randomchoose = r.Next(0, Convert.ToInt32(pd + 1));
listBox1.Items.Add(files[randomchoose]);
//files2[hoho] = files[randomchoose].FullName;
}
}
private void listBox1_MouseDoubleClick(object sender, MouseEventArgs e)
{
//listBox1.SelectedIndex = hoho;
//Process.Start(files2[hoho].FullName);
Process.Start(files[randomchoose].FullName);
}
