Try this:
尝试这个：
string targetFolder = HttpContext.Current.Server.MapPath("~/uploads/logo");
string targetPath = Path.Combine(targetFolder, yourFileName);
file.SaveAs(targetPath);

Your error is the following:
您的错误如下：
bool folder_exists3 = Directory.Exists(Server.MapPath("~/uploads/logo/" + fileName));
if(!folder_exists3)
Directory.CreateDirectory(Server.MapPath("~/uploads/logo/"+fileName));
You check if a directory exists, but you should check if the file exists:
您检查目录是否存在，但您应该检查文件是否存在：
File.Exists(....);

Remove the last part of the path to save you have an extra "/"
删除路径的最后一部分以保存您有一个额外的“/”
It should be
它应该是
file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName);
Also you do not have a file extension set.
您也没有设置文件扩展名。

You need filename
你需要文件名
file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName+"/" + your_image_fillename));
