Solution 1:[1]

I write a demo to convert byte[] image to file and save.

Manage Nuget Packages: System.Drawing.Common ;

public IActionResult Index(byte[] fileBytes)
        {
            
            //Convert byte type pictures into files to save
            var im = new System.IO.MemoryStream(fileBytes);
            var img = Image.FromStream(im);

            //save the file
            img.Save(@"C:\Users\CS\Documents\FedexLabel.png");
    

            //......

        }

Solution 2:[2]

I still use this code

byte[] image2 = response.Shipments[0].ShippingLabel.ToArray();
MemoryStream memoryStream = new MemoryStream(image2);

BinaryReader rd = new BinaryReader(memoryStream);

string filename = "C:/Users/CS/Documents/FedexLabel.png";

byte[] buffer = new byte[1024];
FileStream outFile = new FileStream(filename, FileMode.Create);

int bytesRead;

while ((bytesRead = memoryStream.Read(buffer, 0, buffer.Length)) != 0)
    outFile.Write(buffer, 0, bytesRead);

outFile.Close();
