Aspose. Words: the problem of exporting dt to word, aspose. wordsdt

Solution: import the extracted data to a word document. The exported text and image are successfully exported. Run Main () to export dt to word.

To be resolved: Import multiple pieces of data (text and image into one word document) From dt to word; error messages discovered"An item with the same key has been added"

Dll library used: Aspose. Words and template file 2.docx

 

The complete code is as follows. Execute Main () to export.

Private void Main () {var dic = new Dictionary <string, string> (); Document doc = new Document (Server. mapPath (@ "2.doc"); // template file path string StrID = Request. form ["YX_CH"]; // obtain the value of the foreground GridView project. The following dt is used as one of the query conditions, in addition, nodeid is the node number if (StrID = null) {WebMsgBox. show ("You have not selected any data! ");} DataTable dt = bArticle. getList ("nodeid = '" + Request. queryString ["nodeid"] + "'and ArticleID in (" + StrID + ")"). tables [0]; // if (dt. rows. count> 0) // {// for (int I = 0; I <dt. rows. count; I ++ )//{
// The above four lines comment on the for Loop (start)
Dic. add ("title", dt. rows [0] ["art_title"]. toString (); // The first line starting with "An item with the same key already added", indicated by the browser in dic. add ("date", dt. rows [0] ["art_pubdate"]. toString (); dic. add ("image", Server. mapPath (@ "/UploadFiles/Images/") + dt. rows [0] ["art_img"]. toString (); // replace doc = new Document (Server. mapPath (@ "2.doc"); foreach (var key in dic. keys) {if (key! = "Image") {var repStr = string. format ("& {0} &", key); doc. range. replace (repStr, dic [key], false, false);} else {Regex reg = new Regex ("& Image &"); doc. range. replace (reg, new ReplaceAndInsertImage (Server. mapPath (@ "/UploadFiles/Images/") + dt. rows [I] ["art_img"]. toString (), false );}}//}//}

// The above four lines comment on the for Loop (end)

Doc. Save (Server. MapPath (@ "2ks.doc"); // Save the exported file Response. End ();}
// Public class ReplaceAndInsertImage: IReplacingCallback {// <summary> // path of the image to be inserted /// </summary> public string url {get; set;} public ReplaceAndInsertImage (string url) {this. url = url;} public ReplaceAction Replacing (ReplacingArgs e) {// get the current node var node = e. matchNode; // get the current Document doc = node. document as Document; DocumentBuilder builder = new DocumentBuilder (doc); // move the cursor to the builder of the specified node. moveTo (node); // insert image builder. insertImage (url); return ReplaceAction. replace ;}}

The simplified Main method, but only outputs a piece of data.

Private void Main () {Document doc = new Document (Server. mapPath (@ "2.doc"); DataTable dt = bArticle. getList ("nodeid = '4 '"). tables [0]; if (dt. rows. count> 0) {for (int I = 0; I <dt. rows. count; I ++) {doc. range. replace ("& Title &", dt. rows [2] ["art_title"]. toString (), false, false); doc. range. replace ("& Date &", dt. rows [I] ["art_pubdate"]. toString (), false, false );
Regex reg = new Regex ("& Image &"); doc. range. replace (reg, new ReplaceAndInsertImage (Server. mapPath (@ "/UploadFiles/Images/") + dt. rows [I] ["art_img"]. toString (), false);} doc. save (Server. mapPath (@ "2ks.doc"); Response. end ();}}
