When I receive a file from C# to iformfile, how do I know the file path of that file? If I don't know, how do I set the path?
public async Task<JObject> files(IFormFile files){
string filePath = "";
var fileStream = System.IO.File.OpenRead(filePath)
}
In this document, some instructions on IFormFile are introduced:
Files uploaded using the IFormFile technique are buffered in memory or on disk on the server before processing. Inside the action method, the IFormFile contents are accessible as a Stream.
So for IFormFile, you need to save it locally before using the local path.
For example:
// Uses Path.GetTempFileName to return a full path for a file, including the file name.
var filePath = Path.GetTempFileName();
using (var stream = System.IO.File.Create(filePath))
{
// The formFile is the method parameter which type is IFormFile
// Saves the files to the local file system using a file name generated by the app.
await formFile.CopyToAsync(stream);
}
After this, you can get the local file path, namely filePath.
