将Base64string转换为图像时获取此错误Read.TimeOut和Write.TimeOut

Question

Read.TimeOut：“ stream.Read.TimeOut”引发了类型异常 'System.InvalidOperationException' 和“获取错误”参数无效，这是什么问题，哪里有问题？

public ActionResult AddNewProduct(string thumb_values)
{   
    var ImageCode = thumb_values.Split(',');
    var imagepart = ImageCode[1];
    byte[] data = Encoding.UTF8.GetBytes(imagepart);
    string b64 = Convert.ToBase64String(data);
    Base64ToImage(b64);
    return View();
 }   




public Image Base64ToImage(string base64String)
{     
    byte[] imageBytes = Convert.FromBase64String(base64String);
    using (var ms = new MemoryStream(imageBytes, 0, imageBytes.Length))
    {
        Image image = Image.FromStream(ms, true);//Getting Error here 
        parameter is not valid 
        return image;
    }
}

我想将base64string转换为图像，以及如何将该图像保存到任何路径？
