i have tried and downloaded using ".xlsx". It will be downloaded in new tab and asks to user where to save the particular file.

But when i have tried same for xml download, it does not happen.

Here is the code for .xlsx

fileName = downloadFileName + "_" + currentTime + ".xlsx";
     System.Web.HttpContext.Current.Response.Clear();
     System.Web.HttpContext.Current.Response.ClearContent();
     System.Web.HttpContext.Current.Response.ClearHeaders();
     System.Web.HttpContext.Current.Response.Buffer = true;
     System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
                                                                                                                                                                                                                                    System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
      System.Web.HttpContext.Current.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
      System.Web.HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=" + fileName);
      System.Web.HttpContext.Current.Response.BinaryWrite(xlPackage.GetAsByteArray());
      System.Web.HttpContext.Current.Response.End();
      System.Web.HttpContext.Current.Response.SuppressContent = true;

This code works fine when downloading for xlsx. Below code is used to download for Xml, Which i could able to do.

 string downloadFileName = "Template_Xml";
                    string currentTime = DateTime.Now.ToString("ddMMyyyyhhmmss");
                    fileName = downloadFileName + "_" + currentTime + ".xml";
                    System.Web.HttpContext.Current.Response.Clear();
                    System.Web.HttpContext.Current.Response.ClearContent();
                    System.Web.HttpContext.Current.Response.ClearHeaders();
                    System.Web.HttpContext.Current.Response.Buffer = true;
                    System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
                    System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                    System.Web.HttpContext.Current.Response.ContentType = "text/xml";
                    System.Web.HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=" + fileName);

// Xmldocument creation

  XmlDocument docConfig = new XmlDocument();
  XmlNode xmlNode = docConfig.CreateNode(XmlNodeType.XmlDeclaration, "", "");
  XmlElement rootElement = docConfig.CreateElement("User");
  docConfig.AppendChild(rootElement);
  XmlElement environmentElement = docConfig.CreateElement("NAME");
  XmlText environText = docConfig.CreateTextNode("ABC" + i);
  environmentElement.AppendChild(environText);
  hedder.PrependChild(environmentElement);

  System.Web.HttpContext.Current.Response.BinaryWrite(docConfig); // It throws a error
  System.Web.HttpContext.Current.Response.End();

What I have tried:

Here is the code for downloading XML,

<pre> string downloadFileName = "Template_Xml";
                    string currentTime = DateTime.Now.ToString("ddMMyyyyhhmmss");
                    fileName = downloadFileName + "_" + currentTime + ".xml";
                    System.Web.HttpContext.Current.Response.Clear();
                    System.Web.HttpContext.Current.Response.ClearContent();
                    System.Web.HttpContext.Current.Response.ClearHeaders();
                    System.Web.HttpContext.Current.Response.Buffer = true;
                    System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
                    System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                    System.Web.HttpContext.Current.Response.ContentType = "text/xml";
                    System.Web.HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=" + fileName);

// Xmldocument creation

  XmlDocument docConfig = new XmlDocument();
  XmlNode xmlNode = docConfig.CreateNode(XmlNodeType.XmlDeclaration, "", "");
  XmlElement rootElement = docConfig.CreateElement("User");
  docConfig.AppendChild(rootElement);
  XmlElement environmentElement = docConfig.CreateElement("NAME");
  XmlText environText = docConfig.CreateTextNode("ABC" + i);
  environmentElement.AppendChild(environText);
  hedder.PrependChild(environmentElement);

  System.Web.HttpContext.Current.Response.BinaryWrite(docConfig); // It throws a error
  System.Web.HttpContext.Current.Response.End();

What is the error?

Error 5 The best overloaded method match for 'System.Web.HttpResponse.BinaryWrite(byte[])' has some invalid arguments

Error 6 Argument 1: cannot convert from 'System.Xml.XmlDocument' to 'byte[]'

These 2 errors iam getting

Look at the documentation for BinaryWrite and you'll see it only accepts an array of bytes as a parameter (byte[]) and you are passing an XmlDocument. It doesn't know how to turn an XmlDocument into an array of bytes so you'll need to do that bit yourself. Google "XmlDocument to byte array"

https://social.msdn.microsoft.com/Forums/sqlserver/en-US/7cdd4bf7-3da3-4735-b710-833ff3ffe693/convert-xml-data-to-byte-array?forum=csharpgeneral

So it'll be something like

System.Web.HttpContext.Current.Response.BinaryWrite(System.Text.Encoding.UTF8.GetBytes(docConfig.OuterXml));
