Hi,

How to avoid Special character in file url in asp.net

Try below code

  strFileName = strFileName.Replace("#", " ")
  strFileName = strFileName.Replace("+", " ")

OR

NavigateUrl = www.ursite.com? + Server.UrlEncode("query string params go here")

Response.Redirect("Default1.aspx?qstr=" + Server.UrlEncode(YourString));
