我有一个带有后台工作程序（bgw）的 Windows 窗体应用程序。此 bgw 执行一些任务，在这些任务中，有以下这些： 第 2 步 - 使用以下代码将文件从一个文件夹复制到另一个文件夹：
public static void CopiarArquivos()
{
string fileName;
string sourcePath = System.Windows.Forms.Application.StartupPath;
const string targetPath = @"C:\CWEB\CwebIntegracaoMovel";
if (sourcePath == targetPath) return;
string destFile;
// To copy a folder's contents to a new location:
// Create a new target folder, if necessary.
if (!Directory.Exists(targetPath))
{
Directory.CreateDirectory(targetPath);
}
if (Directory.Exists(sourcePath))
{
string[] files = Directory.GetFiles(sourcePath);
//Invoke((MethodInvoker)(() => {
//});
// Copy the files and overwrite destination files if they already exist.
foreach (string s in files)
{
FileInfo fi = new FileInfo(s);
// Use static Path methods to extract only the file name from the path.
fileName = Path.GetFileName(s);
destFile = Path.Combine(targetPath, fileName);
if (!ArquivosIguais(s, destFile) &&
(!fileName.Contains("WizardIntegracao.exe") ||
(fileName.Contains("WizardIntegracao.exe") && !File.Exists(destFile))))
{
fi.CopyTo(destFile, true);
//File.Copy(s, destFile, true);
//new System.Security.Permissions.FileIOPermission(
// System.Security.Permissions.FileIOPermissionAccess.Read, new string[] { destFile }).Demand();
}
}
}
}
副本工作正常（有一些行被注释掉，因为我已经测试了一些其他的东西）在 bgw 的第 4 步中，我更改了在第 2 步中复制的 .config 文件的一些设置，代码如下：
public static void AlteraBaseAddress(string porta)
{
string path = "C:\\CWEB\\CwebIntegracaoMovel\\ServicoIntegracao.exe.config";
string conteudo = File.ReadAllText(path);
int inicio = conteudo.IndexOf("http://");
int fim = conteudo.IndexOf("/ServicoIntegracao/Servico");
conteudo = conteudo.Remove(inicio, fim - inicio);
conteudo = conteudo.Insert(inicio, String.Format("http://localhost:{0}", porta));
File.WriteAllText(path, conteudo);
}
当我运行我的应用程序时，我得到了异常：
Ocorreu um erro no processo de instalação do serviço:
O acesso ao caminho 'C:\CWEB\CwebIntegracaoMovel\ServicoIntegracao.exe.config' foi negado..
em System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
em System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy)

em System.IO.StreamWriter.CreateFile(String path, Boolean append)
em System.IO.StreamWriter..ctor(String path, Boolean append, Encoding encoding, Int32 bufferSize)
em System.IO.StreamWriter..ctor(String path, Boolean append, Encoding encoding)
虽然尝试更改 .config 文件的内容时发生错误，但据我所知，复制文件时发生错误，它们被我自己的应用程序锁定，然后我无法覆盖它的内容。
有谁知道如何使这项工作？
