J'essaie d'afficher les numéros de version de l'ancien et du nouveau à l'utilisateur, puis copiez la nouvelle version. Quand je tentais copier le fichier après avoir affiché les informations de version que je reçois l'exception suivanteDisposing assembly
Le processus ne peut pas accéder au fichier « C: \ Auto TEC \ common.dll » parce qu'il est utilisé par un autre processus.
Voici le code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Reflection;
using System.Diagnostics;
namespace copyfile
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string sourceDirectory = @"E:\newversion\Auto TEC";
string targetDirectory = @"C:\Auto TEC";
Copy(sourceDirectory, targetDirectory);
label3.Text = "sucess";
loadAssembyNames();
}
void f2_FormClosed(object sender, FormClosedEventArgs e)
{
this.Close();
}
public static void Copy(string sourceDirectory, string targetDirectory)
{
DirectoryInfo diSource = new DirectoryInfo(sourceDirectory);
DirectoryInfo diTarget = new DirectoryInfo(targetDirectory);
CopyAll(diSource, diTarget);
}
public static void CopyAll(DirectoryInfo source, DirectoryInfo target)
{
// Check if the target directory exists, if not, create it.
if (Directory.Exists(target.FullName) == false)
{
Directory.CreateDirectory(target.FullName);
}
// Copy each file into it's new directory.
foreach (FileInfo fi in source.GetFiles())
{
fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
}
// Copy each subdirectory using recursion.
foreach (DirectoryInfo diSourceSubDir in source.GetDirectories())
{
DirectoryInfo nextTargetSubDir =
target.CreateSubdirectory(diSourceSubDir.Name);
CopyAll(diSourceSubDir, nextTargetSubDir);
}
}
string _errMsg;
//private AssemblyInformation _info;
private void getfilenames(string directoryPath, int location)
{
string[] path = new string[25];
int count = 0;
foreach (string file in System.IO.Directory.GetFiles(directoryPath))
{
path[count] = file;
count++;
}
Assembly asm = null;
for (int i = 0; i < count; i++)
{
try
{
//asm = Assembly.LoadFrom(path[i]);
asm = Assembly.LoadFile(path[i]);
if (asm != null)
{
if (location == 1)
{
listBox1.Items.Add(asm.GetName().Name + asm.GetName().Version.ToString());
}
else
{
listBox2.Items.Add(asm.GetName().Name + asm.GetName().Version.ToString());
}
}
}
catch (Exception err)
{
this._errMsg = err.Message;
}
}
asm = null;
GC.Collect();
}
private void Form1_Load(object sender, EventArgs e)
{
loadAssembyNames();
}
private void loadAssembyNames()
{
listBox1.Items.Clear();
listBox2.Items.Clear();
getfilenames(@"C:\Auto TEC", 1);
getfilenames(@"E:\newversion\Auto TEC", 2);
}
}
}
Comment puis-je décharger les informations d'assemblage de l'objet?
