C# IE、Chrome、Firefox下載方法判斷 - 解決下載檔名亂碼問題

JDP

主要是要判斷瀏覽器是否是IE，如果是IE，檔名需要先使用Urlencode編碼，如果是Chrome或Firefox則不需要，用這種方式才可避免下載的檔名變亂碼！

1. #region 判斷瀏覽器版本
   
2. HttpContext.Current.Response.ContentType = "application/octet-stream";
   
3. HttpBrowserCapabilities brObject = HttpContext.Current.Request.Browser;
   
4. string Tourversion = brObject.Type;
   
5. if (Tourversion == "IE11" || Tourversion == "IE10" || Tourversion == "IE9" || Tourversion == "IE8" || Tourversion == "IE7" || Tourversion == "IE6" || Tourversion == "InternetExplorer11")
   
6. {
   
7.    HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode("" + mobanName + "" + "." + format, System.Text.Encoding.UTF8));
   
8. }
   
9. else if (Tourversion.Contains("Chrome") || Tourversion.Contains("Firefox"))
   
10. {
    
11.   string fileName = mobanName + "." + format;
    
12.   HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName);
    
13. }
    
14. #endregion

複製代碼
