To copy an IFormFile
to another path or disk in .NET, you can use the CopyToAsync()
method of the IFormFile
object to copy the contents of the file to a new file in the desired location. Here's an example:
csharp[HttpPost]
public async Task<IActionResult> Upload(IFormFile file)
{
if (file != null && file.Length > 0)
{
// Get the filename and extension
string fileName = Path.GetFileNameWithoutExtension(file.FileName);
string fileExtension = Path.GetExtension(file.FileName);
// Create a unique filename
string newFileName = fileName + "_" + Guid.NewGuid().ToString("N") + fileExtension;
// Specify the destination path and filename
string destinationPath = @"C:\MyFiles\" + newFileName;
// Copy the file to the destination
using (var stream = new FileStream(destinationPath, FileMode.Create))
{
await file.CopyToAsync(stream);
}
// Return a success message
return Ok("File uploaded successfully!");
}
// Handle errors
return BadRequest("No file was uploaded.");
}
In this example, we first check if the file is not null and has a length greater than 0. We then get the filename and extension of the file using the Path.GetFileNameWithoutExtension()
and Path.GetExtension()
methods. We create a unique filename by appending a GUID to the original filename, and specify the destination path using a string. We then create a new FileStream
object with the destination path and filename, and use the CopyToAsync()
method of the IFormFile
object to copy the contents of the file to the stream. Finally, we return a success message if the upload was successful.
Note that in this example, we are using a hard-coded destination path (@"C:\MyFiles\"
). You should replace this with a path that is appropriate for your application, and make sure that the destination directory exists and is writable.
