首先有個這樣的需求,將以下網頁內容下載為Word文件。
html代碼:
<div class="modal-body">
<div>ZY1703220001號標的開標結果為貴方中標,現通知如下:</td>
</tr>
</table>
<table border="1" cellspacing="0" cellpadding="10">ZY1703220001</td>
<td>25.725</td>
<td>47500.00</td>
<td>XX</td>
<td>XXXXXX</td>
</tr>
<tr>
<td colspan="6">備注:XXXXXX</td>
</tr>
</table>
<table>
第一步:封裝一個方法
1:在控制器BiddingNoticeManageController創建一個DownBiddingNoticeModal方法。(采用的MVC模式)
2:根據id查詢當前中標信息(EF)
3:建一個中標通知書的html模板頁(數據字段自定義占位符)
3-1:注:html模板中不需要<html>、<head>、<title>、<body>等標簽。只是單純的div布局標簽
3-2:布局標簽中的樣式必須是內聯,就是寫在標簽中,不能寫在外部.css中。
4:通過Stream、StreamReader兩個類來讀取這個模板文件(返回的是html字符串)。
5:2中查詢出數據(對應字段)替換4中返回的html字符串中的占位符。
6:關鍵代碼
StringBuilder sb = new StringBuilder();
sb.Append(
"<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:w=\"urn:schemas-microsoft-com:office:word\" xmlns:m=\"http://schemas.microsoft.com/office/2004/12/omml\"xmlns = \"http://www.w3.org/TR/REC-html40\">");
sb.Append(html);
sb.Append("</html>");
7:用法:在頁面前端寫一個a標簽指向這個方法即可下載為Word文件了。
HTML模板文件:
<div class="modal-body">
<div >
<table >
<tr>
<td >中標通知書<hr /></td>
</tr>
<tr>
<td >@BidderName</td>
</tr>
<tr>
<td > “XXXX物資平台”@ResourceCode號標的開標結果為貴方中標,現通知如下:</td>
</tr>
</table>
<table border="1" cellspacing="0" cellpadding="10" >
<tr >
<th>品名</th>
<th>資源編號</th>
<th>數量(@Unit)</th>
<th>中標價格(含稅總金額:元)</th>
<th>鋼廠</th>
<th>存放地(提貨地)</th>

<tr >
<td>@ResourceName</td>
<td>@ResourceCode</td>

<td colspan="6">備注:@Remarks</td>

</table>
<table >
