C#代碼將html樣式文件轉為Word文檔,

編輯:C#入門知識

C#代碼將html樣式文件轉為Word文檔,


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>
            <tr >
                <td>@ResourceName</td>
                <td>@ResourceCode</td>
                <td>@Count</td>
                <td>@TenderPrice</td>
                <td>@BrandName</td>
                <td>@InventoryPlace</td>
            </tr>
            <tr>
                <td colspan="6">備注:@Remarks</td>
            </tr>
        </table>
        <table >
            <tr>
                <td >
                    請貴方在收到通知書的5個工作日內交齊全額貨款並簽訂合同。
                </td>
            </tr>
            <tr>
                <td >
                    特此通知。
                </td>
            </tr>
            <tr>
                <td >
                    XXXX物資平台
                </td>
            </tr>
            <tr>
                <td >
                    @Year 年 @Moth 月 @Day 日
                </td>
            </tr>
        </table>
