Cannot remove zip file from folder on click of linkbutton in gridview

Question

I have a gridview in which there is a column to 'Remove zip file'. The zip file in question is being added by the user to a folder in the application and the name is stored in the database. Each row of the GridView has a zip file associated with it. Now, when I click on the 'Remove Zip file' button in GridView, I want to delete this zip file. Here is the code I am using.

XML

<asp:GridView ID="gvrecord" runat="server" AutoGenerateColumns="False" BackColor="White"
        BorderStyle="None" BorderWidth="1px" CellPadding="4" onrowcancelingedit="gvrecord_RowCancelingEdit"
           onrowdatabound="gvrecord_RowDataBound" onrowdeleting="gvrecord_RowDeleting"
           onrowediting="gvrecord_RowEditing" onrowupdating="gvrecord_RowUpdating" Height="168px"
                       Width="850px">
            <RowStyle BackColor="White"/>
           <Columns>
                   <asp:TemplateField HeaderText="PROJECT ID" ItemStyle-Font-Size="12px">
                   <ItemTemplate>
                       <asp:Label ID="Label2" runat="server" Text='<%#Bind("ProjectId") %>'></asp:Label>
                   </ItemTemplate>
                   </asp:TemplateField>
                   <asp:TemplateField HeaderText="JOB TITLE" ItemStyle-Font-Size="12px">
                   <ItemTemplate>
                       <asp:Label ID="lbljob" runat="server" Text='<%#Bind("jobtitle") %>'></asp:Label>
                   </ItemTemplate>

XML

<asp:TemplateField ItemStyle-Font-Size="12px">
                   <ItemTemplate>
                       <asp:LinkButton ID="lnkremovezip" runat="server" OnClick="lnkremovezip_Click">Remove Zip File</asp:LinkButton>
                   </ItemTemplate>
                   </asp:TemplateField>

and here is the code for the lnkremovezip_Click()

C#

protected void lnkremovezip_Click(object sender, EventArgs e)
{
   LinkButton lnkzipremove = (LinkButton)sender;
   GridViewRow row = (GridViewRow)lnkzipremove.NamingContainer;
   Label lblzipfile = (Label)row.FindControl("lblzip");
   string path = "~/ZipFiles/" + lblzipfile.Text;
   FileInfo file = new FileInfo(path);
   if (file.Exists)
   {
       file.Delete();
   }
}

I put breakpoints in the code and found that when the execution gets to the 'if' statement, the condition is false and it doesn't execute the file.Delete().The zip file is present in the /ZipFiles/ folder.

Can somebody please help me figure out where I've gone wrong?

You can check by copy value from path variable and paste in run Command or windows explorer to check whether it pointing to correct file. alternatively you can try
Server.MapPath(path);
to get exact path in your solution

try this you are missing Server.MapPath

C#

protected void lnkremovezip_Click(object sender, EventArgs e)
{
LinkButton lnkzipremove = (LinkButton)sender;
GridViewRow row = (GridViewRow)lnkzipremove.NamingContainer;
Label lblzipfile = (Label)row.FindControl("lblzip");
string path = "~/ZipFiles/" + lblzipfile.Text;
FileInfo file = new FileInfo(Server.MapPath(path));
if (file.Exists)
{
file.Delete();
}
}

Hey Guys,
I figured out the problem. Just needed to add Server.MapPath to the path.

C#

FileInfo file=new FileInfo(Server.MapPath(path));
