I just started to use this ionic.zip.dll to create zip files which user can download.
My problem is after click the "download" button, nothing happens. I set break point and checked, seems the zip file has the files added, but somehow nothing happens. I tried in firefox and ie, neither one works.
I then added a try catch block and got this error message:
Message = Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.
The Error occurs after Response.End(); so I have no clue what caused it.
please see my code below:
ZipFile zip = new ZipFile();
for (int i = 0; i < lbxlist.Items.Count; i++)
List<string> paths = getScannedFormPath(lbxlist.Items[i].Value, Convert.ToInt32(cbyear.SelectedValue));
for (int j = 0; j < paths.Count; j++)
string s = paths[j].ToString();
Response.AddHeader("Content-Disposition", "attachment; filename=forms.zip");
Response.ContentType = "application/zip";
