推荐答案

这是我完成的代码，它工作正常.

This is the code which i had done it is working fine.

public void PostFile(IFormFile file)
{          
    var uploads = Path.Combine("ROOT PATH FOR THE FILES", "uploads");

    if (file.Length > 0)
    {
        var filePath = Path.Combine(uploads, file.FileName);

        using (var fileStream = new FileStream(filePath, FileMode.Create))
        {
            file.CopyTo(fileStream);
        }
    }
