Hi sani.ss501,

How you are uploading the zip file and where you are uploading?

Share the code.

I register people's general information in the registration form. User images with each person's code are stored in a compressed file. To prevent users from uploading individual images, I want to do this all at once. I will be happy to help you

Hi sani.ss501,

You need to extract the file from Zip and save the details in database.

For extracting file from Zip i am using Ionic.Zip.Reduced library.

For more details refer below article.

Upload, Unzip and Extract contents Zip Archive file in ASP.Net using C# and VB.Net

For upload files in database refer below article.

Upload and Display Images using Path stored in database in GridView in ASP.Net using C# and VB.Net

Using both the article i have created an example. Refer below example.

HTML

<asp:FileUpload ID="fuUpload" runat="server" />
<asp:Button Text="Save" runat="server" OnClick="OnSave" />
<hr />
<asp:GridView ID="gvFiles" runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="FileId" HeaderText="Id" />
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:ImageField DataImageUrlField="Path" HeaderText="Image" />
    </Columns>
</asp:GridView>
