以下是工作示例供您参考:

Here is the working example for your reference:

您在这里犯的错误是您的BLL您存储客户端文件路径的代码.
您的代码应该像这样

The mistake you are doing here is in your BLL code you are storing the client''s file path.
Your code should go something like this

string serverFilePath = Server.MapPath("@~/users_images/" + File1.PostedFile.FileName);
File1.SaveAs(serverFilePath);
objbll.Images = serverFilePath;
