Winforms Listbox數據綁定到目錄中的文件列表

Question

我想將目錄中的文件列表綁定到列表框。

這裏是我想要的代碼片段，我嘗試到目前爲止，lstFiles是一個ListBox，我想要將Files屬性綁定到。但是ListBox是空的。請幫忙。

public partial class Form1 : Form, INotifyPropertyChanged 
    { 
     private IList<FileInfo> _files = new List<FileInfo>(); 
     public IList<FileInfo> Files 
     { 
      get 
      { 
       return this._files; 
      } 
      set 
      { 
       if (value != this._files) 
       { 
        this._files = value; 
        NotifyPropertyChanged("Files"); 
       } 
      } 
     } 
     public Form1() 
     { 
      InitializeComponent(); 

      lstFiles.DataSource = Files; 
      lstFiles.DataBindings.Add("Name", Files, "Files"); 
      lstFiles.DisplayMember = "Name"; 
     } 

     private void btnStartPath_Click(object sender, EventArgs e) 
     { 
      var dialog = new FolderBrowserDialog(); 
      var result = dialog.ShowDialog(); 
      if (result == DialogResult.OK) 
      { 
       txtStartPath.Text = dialog.SelectedPath; 
      } 
     } 

     private void btnFind_Click(object sender, EventArgs e) 
     { 
      Files = new DirectoryInfo(txtStartPath.Text).EnumerateFiles().ToList(); 
     } 

     #region INotifyPropertyChanged Members 

     public event PropertyChangedEventHandler PropertyChanged; 

     private void NotifyPropertyChanged(String info) 
     { 
      if (PropertyChanged != null) 
      { 
       PropertyChanged(this, new PropertyChangedEventArgs(info)); 
      } 
     } 
     #endregion 
} 

Answer 1

您必須設置值成員屬性。我想這對於例如：

 IList<FileInfo> myList = new List<FileInfo>(); 
     FileInfo test1 = new FileInfo(@"G:\test.xls"); 
     myList.Add(test1); 

     listBox1.DisplayMember = "Name"; 
     listBox1.ValueMember = "FullName"; 
     listBox1.DataSource = myList; 

可正常工作:)

我沒有看到添加文件在你的代碼上市，

DirectoryInfo dinfo = new DirectoryInfo(@"C:\Directory"); 

文件類型，

_files = dinfo.GetFiles("*.txt"); 

然後

foreach(FileInfo file in Files) 
{ 
    listbox1.Items.Add(file.Name); 
}
