First, define document type, character encoding
Response.clear ();
Response.buffer = true;
Response.Charset = "UTF-8";
// This is very important, the attachment parameter represents the download as an attachment, you can change it to ONLINE
//filename=FileFlow.xls Specifies the name of the output file, pay attention to its extension and specified file type, can be: .doc || .xls ||.txt || .htm
Response.Appendheader ("Content-Disposition", "Attachment; FileName = fileflow.xls");
Response.contentencoding = system.text.Encoding.Getencoding ("UTF-8");
//Response.contentType Specify file types can be Application / MS-Excel || Application / MS-Word || Application / MS-TXT || Application / MS-HTML || or other browser to support documentation directly
Response.contentType = "Application / MS-Excel";
THIS.ENABLEVIEWSTATE = false;
Second, define an input stream
System.io.stringwriter ostringwriter = new system.io.stringwriter ();
System.Web.ui.htmlTextWriter OhtmlTextWriter = new system.web.ui.htmlTextWriter;
Third, bind the target data to the input stream output
THIS.RenderControl (OhtmlTextWriter);
// this represents the output page, you can also bind DataGrid, or other controls that support Obj.RenderControl () properties
Response.write (ostringwriter.tostring ());
Response.end ();
Summary: This routine is tested under the Microsoft Visual Studio .Net 2003 platform, for C # and VB, change the THIS keyword to ME when using VB.
A simplified way:
Response.clear ()
Response.buffer = TRUE
Response.charset = "GB2312"
Response.Appendheader ("Content-Disposition", "Attachment; FileName =" System.Datetime.today.toshortdateString () ".xls")
Response.contentencoding = system.text.Encoding.getencoding ("GB2312")
Response.contentType = "Application / MS-Excel"
ME.enableViewState = false
Dim Mycitrad AS New System.globalization.cultureInfo ("ZH-CN", TRUE)
Dim OstringWriter as new system.io.stringWriter (MyCITRAD)
Dim ohtmltextwriter as new system.web.ui.htmlTextWriter (OstringWriter) GridView1.RenderControl (OhtmlTextWriter)
Response.write (ostringwriter.tostring ())
Response.end ()
