我是一個WPF和c＃中的begginer。我無法達到將一個對象綁定到數據網格
我有一個簡單的WPF應用程序，其中有一個數據網格。我想填充它，當我點擊一個按鈕：
private void buttonTest_Click(object sender, RoutedEventArgs e)
{
File files = new File(this.textBoxScegliSorgente.Text, datePicker.SelectedDate.Value);
this.dataGridElencoFiles.DataContext = files;
}
File類是這樣的：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Security.AccessControl;
using System.Reflection;
using System.Collections;
using System.ComponentModel;
namespace ArchiviazioneVecchiDocumenti
{
public class File
{
private List<string> percorso = new List<string>();
public List<string> Percorso
{ get { return percorso; } }
private List<string> nomeFile = new List<string>();
public List<string> NomeFile
{ get { return nomeFile; } }
private List<DateTime> dataUltimaModifica = new List<DateTime>();
public List<DateTime> DataUltimaModifica
{ get { return dataUltimaModifica; } }
private List<DateTime> dataUltimoAccesso = new List<DateTime>();
public List<DateTime> DataUltimoAccesso
{ get { return dataUltimoAccesso; } }
private List<long> dimensione = new List<long>();
public List<long> Dimensione
{ get { return dimensione; } }
private List<string> logErrori = new List<string>();
public List<string> LogErrori
{ get { return logErrori; } }
/* campi recuperati provvisori */
private DirectoryInfo sorgente;
private DirectoryInfo destinazione;
private DateTime data;
private string radioscelta;
private bool test;
private DirectoryInfo[] directories;
private FileInfo[] filesInDir;
private WshShellClass WshShell;
public File(string sorgente, DateTime data)
{
this.sorgente = new DirectoryInfo(sorgente);
this.data = data;
this.test = true;
ExploreDirectory(this.sorgente);
}
private void ExploreDirectory(DirectoryInfo dir)
{
try
{
this.filesInDir = dir.GetFiles();
}
catch (Exception e)
{
this.logErrori.Add(e.Message[0].ToString());
}
foreach (FileInfo file in filesInDir)
{
if (file.Extension != ".lnk")
{
if (file.LastWriteTime < this.data)
{
if (this.test == true)
{
try
{
List<string> veraPathLunga = new List<string>();
veraPathLunga.Add(dir.Name + "\\");
DirectoryInfo temp = dir;
while (temp.Name != this.sorgente.Name)
{
veraPathLunga.Add(temp.Parent.ToString() + "\\");
temp = temp.Parent;
}
veraPathLunga.Reverse();
veraPathLunga[0] = this.sorgente.FullName;
string percorsoFileUnito = string.Join("", veraPathLunga.ToArray());
this.percorso.Add(percorsoFileUnito);
this.nomeFile.Add(file.Name);
this.dimensione.Add(file.Length);
this.dataUltimaModifica.Add(file.LastWriteTime);
this.dataUltimoAccesso.Add(file.LastAccessTime);
}
catch (Exception e)
{
this.logErrori.Add(e.Message[0].ToString());
}
}
}
}
}
try
{
this.directories = dir.GetDirectories();
}
catch (Exception e)
{
this.logErrori.Add(dir.Name + " " + e.Message[0].ToString());
}
foreach (DirectoryInfo newDir in this.directories)
{
ExploreDirectory(newDir);
}
}
}
}

誰能給我個忙嗎？
感謝
所以「Percorso」和「Nome File」是字符串列表嗎？你想如何綁定這些在網格中工作 - 一個字符串列表應該如何顯示在一個單元格中？ – 2010-07-31 19:03:08
