获取用于转换为base 64字符串的图像路径

I have an image in my images folder

我的图像文件夹中有一个图像

and I want to pass this image to an Image object so I can then convert it to a base 64 string. This will then be passed to the client and inserted into the src of a img element.

我想将此图像传递给Image对象，然后我可以将其转换为基本64字符串。然后将其传递给客户端并插入到img元素的src中。

The problem is that I don't know how to get the image from disk into the image object.

问题是我不知道如何将图像从磁盘放入图像对象。

Image img = Image.FromFile(@"..Images\no_image.jpg"); // doesn't work

string image = Convert.ToBase64String(imageToByteArray(img));


public byte[] imageToByteArray(Image imageIn)
    {
        MemoryStream ms = new MemoryStream();
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
        return ms.ToArray();
    }

If you work on a web project, you should use:

如果您在Web项目上工作，则应使用：

Image.FromFile(Server.MapPath("~/Images/no_image.jpg"))

else if it is a WinForm/WPF/Console application, use:

否则，如果它是WinForm / WPF / Console应用程序，请使用：

Image.FromFile(System.IO.Path.Combine(Environment.CurrentDirectory, "Images", "no_image.jpg"))
