Hi, Below is an equivalent .NET MAUI code snippet for copying a large file (5GB) from a source to a destination using impersonation:
C#
using System;
using System.IO;
using System.Security.Principal;
using Microsoft.Maui.Essentials;
namespace FileCopyApp
{
public class FileCopyService
{
public async Task CopyFileAsync(string sourceFilePath, string destinationFilePath)
{
try
{
// Impersonate a user (e.g., service account) for the file copy operation
await ImpersonateUserAsync(async () =>
{
// Perform the file copy
await File.CopyAsync(sourceFilePath, destinationFilePath);
Console.WriteLine("File copied successfully!");
});
}
catch (Exception ex)
{
Console.WriteLine($"Error copying file: {ex.Message}");
}
}
private async Task ImpersonateUserAsync(Func<Task> action)
{
// Replace ImpersonationHelper.Token with the actual token or credentials for impersonation
// Ensure that the account used has appropriate permissions to read from the source and write to the destination
// Example: Impersonate using a service account token
var impersonationResult = await ImpersonateHelper.ImpersonateAsync(ImpersonationHelper.Token);
if (impersonationResult.Success)
{
try
{
await action.Invoke();
}
finally
{
// Revert impersonation
await ImpersonateHelper.RevertImpersonationAsync();
}
}
else
{
Console.WriteLine($"Impersonation failed: {impersonationResult.ErrorMessage}");
}
}
}
}
In this .NET MAUI code:
Replace sourceFilePath and destinationFilePath with the actual paths of your source and destination files. The ImpersonateUserAsync method handles impersonation using the ImpersonateHelper class (similar to the previous example). Ensure that the account used for impersonation has the necessary permissions to read from the source location and write to the destination location. Remember to adjust the code according to your specific requirements and security considerations when integrating it into your .NET MAUI app.
