有没有办法在 ASP Core 的静态类中使用“IWebHostEnvironment”？

我的课 ：

public class MainHelper
{
    private readonly IWebHostEnvironment _hostingEnvironment;

    public MainHelper(IWebHostEnvironment hostingEnvironment)
    {
        _hostingEnvironment = hostingEnvironment;
    }    

    public static void SaveFile(IFormFile file)
    {
            var path = Path.Combine(_hostingEnvironment.WebRootPath, "uploads");
            if (!Directory.Exists(path))
                Directory.CreateDirectory(path);

            using (var fileStream = System.IO.File.Create(Path.Combine(path, file.FileName)))
            {
                file.CopyTo(fileStream);
            }
    }
}

我的行有错误：

var path = Path.Combine(_hostingEnvironment.WebRootPath, "uploads");

错误： c# 会话非静态字段方法或属性“MainHelper._hostingEnvironment”需要对象引用

请指教
