我如何搜索文件夹中的文件及其文件夹然后在Listview C＃中打开它们 [英] How Can I Search Files In A Folder And It's Folder And Then Open Them In Listview C#

问题描述

Hey Guys，

  private   void  button2_Click（ object  sender，EventArgs e）
 {
 尝试 
 {
  //  检查目录是否存在 
  if （Directory.Exists（ @  C：\ data））
 {
  string  names = textBox1.Text +  （ + textBox2.Text +  ） +  。jpg; 
 
  string  [] files = Directory.GetFiles（ @  c：\ data，names，SearchOption.AllDirectories）; 
 
 
  foreach （ string  file  in  files）
 {
  string  filename = Path.GetFileName（file）; 
  string  ext = Path.GetFileNameWithoutExtension（filename）; 
 
 
 ListViewItem item =  new  ListViewItem（file）; 
 
 listView1.Items.Add（item）; 
 
 
 
  foreach （ListViewItem i  in  listView1 .Items）
 {
  if （i.Selected）
 {
 item = i; 
} 
} 
 
  foreach （ string  f 在文件中）
 {
  if （f == item.Text）
 {
 ext = f; 
} 
 
 
} 
 Process.Start（  explorer.exe，Path.GetDirectoryName（ext））; 
 
 
 
 
 
} 
 
 
} 
 
 
 
 
 
  else  
 MessageBox.Show（ KLASÖRBULUNAMADI）; 
} 
  catch （Exception ex）
 {
 MessageBox.Show（ex.Message，  HATA）; 
} 
 
 
} 

喜欢我的代码，我正在尝试搜索C：\ data文件夹中的文件及其子文件夹。然后我想在listview1窗口中列出它们并在我点击它们时打开这些文件夹。可能吗？对于此代码，我的listview上的文件路径列表会自动打开它们的目录。所有我需要的是当我双击它们时打开他们的目录。

解决方案

没有错误消息。它正在工作，但当我点击按钮，路径上列表视图会自动打开。我想通过点击listview上的路径打开这些文件夹



文件正在自动打开因为你正在执行：

 Process.Start（  explorer.exe，Path.GetDirectoryName（ext） ）; 

取出那行代码，并为ListView SelectedIndexChanged事件写一个处理程序：在那个EventHandler做正确的事情打开文件基于哪个ListViewItem（s）是/点击。



为了消除与每个ListViewItem的Value对应的文件路径数据的复杂查找，我会使用一个Dictionary ...就像这样： pre lang =c＃> 私人字典< listviewitem，> dctLVItemToString = new 字典< listviewitem，> （）;

// 模拟：ListView和词典的示例初始化
for （ int i = 0 ; i < 10 ; i ++）
{
string iStr = i.ToString（）;

ListViewItem lvItem = new ListViewItem（iStr）;

listView1.Items.Add（lvItem）;

// 此处模拟的文件路径
dctLVItemToString.Add（ lvItem， file + iStr）;
}

// 在ListView SelectedIndexChanged EventHandler中使用Dictionary的示例：
private void listView1_SelectedIndexChanged（ object sender，EventArgs e）
{
ListView.SelectedListViewItemCollection selectedItems = listView1.SelectedItems;

if （selectedItems.Count！= 0 ）
{
string filePath = dctLVItemToString [selectedItems [ 0 ]];

// 仅用于演示目的
MessageBox.Show（文件路径）;
}
}

想法是简化和加速查询。

Hey Guys,

private void button2_Click(object sender, EventArgs e)
 {
     try
     {
         // Check if directory is present or not
         if (Directory.Exists(@"C:\data"))
         {
             string names = textBox1.Text + "(" + textBox2.Text + ")" + ".jpg";

             string[] files = Directory.GetFiles(@"c:\data", names, SearchOption.AllDirectories);


             foreach (string file in files)
             {
                 string filename = Path.GetFileName(file);
                 string ext = Path.GetFileNameWithoutExtension(filename);


                 ListViewItem item = new ListViewItem(file);

                 listView1.Items.Add(item);



                 foreach (ListViewItem i in listView1.Items)
                 {
                     if (i.Selected)
                     {
                         item = i;
                     }
                 }

                     foreach (string f in files)
                     {
                         if (f == item.Text)
                         {
                             ext = f;
                         }


                     }
              Process.Start("explorer.exe", Path.GetDirectoryName(ext));





             }


         }





         else
             MessageBox.Show("KLASÖR BULUNAMADI");
     }
     catch (Exception ex)
     {
         MessageBox.Show(ex.Message, "HATA");
     }


 }

like on my code, i'm trying to searching files on C:\data folder and it's subfolders. Then i want to list them on my listview1 window and open these folders when i click on them. Is it possible? For this code, filepaths list on my listview and open their directories automatically. All i need is open their directories when i double click on them.

解决方案

"there is no error messages. it is working but when i click on button, paths on the listview are opening automatically. I want to open these folders by clicking on their path on listview"

The files are opening "autotmatically" because you are executing:

Process.Start("explorer.exe", Path.GetDirectoryName(ext));

Take that line of code out, and write a handler for the ListView SelectedIndexChanged Event: in that EventHandler "do the right thing" to open the file(s) based on which ListViewItem(s) was/were clicked on.

To eliminate complex look-up of the filepath data that correspond to each ListViewItem's Value, I would use a Dictionary ... like this:

private Dictionary<listviewitem,> dctLVItemToString = new Dictionary<listviewitem,>(); 

// simulation: sample initialization of a ListView and the Dictionary
for (int i = 0; i < 10; i++)
{
    string iStr = i.ToString();

    ListViewItem lvItem = new ListViewItem(iStr);

    listView1.Items.Add(lvItem);

    // file path simulated here
    dctLVItemToString.Add(lvItem, "file " + iStr);
}

// sample use of the Dictionary in the ListView SelectedIndexChanged EventHandler:
private void listView1_SelectedIndexChanged(object sender, EventArgs e)
{
    ListView.SelectedListViewItemCollection selectedItems = listView1.SelectedItems;

    if (selectedItems.Count != 0)
    {
        string filePath = dctLVItemToString[selectedItems[0]];

        // for demo purposes only
        MessageBox.Show(filePath);
    }
}

The idea is to simplify, and speed-up, look-up.
