ASP.NET MVC による Word レポートのエクスポート

最近、MVCを使用してWordのレポート機能をエクスポートしたいと考えています。情報を確認したところ、Aspose.Word という便利なプラグインがあることがわかりました。このプラグインも非常に有名で使いやすいです。

1. 1つ目はプラグインを引用することです

2. バックグラウンド操作

その中にはビルダーが注意すべき点がいくつかあります。CellFormat.VerticalMerge = CellMerge.None;CellMerge は列挙型であり、複雑なテーブルの描画やセルの結合によく使用されます。 「First」と「Previous」もあります。最初に DataTable データを取得し、最後にデータを操作する必要があります。

4. 出力ドキュメント

private List<double> QuaterAirPM10AvgVolReport(string stns, DateTime start, DateTime end, Aspose.Words.DocumentBuilder builder, out DataTable dt, out List<double> widthList,string isMax)
    {
      dt = QuaterPM10AvgVol (stns, start, end,isMax);
      widthList = new List<double>();
      double[] colWidth = new double[] { 50, 118, 117, 50, 118, 117 };
      string[] colName = new string[] { "排序", "城市", start.Year + "年" + start.Month + "～"+end.Month+"月浓度(μg/m3)", "排序", "城市", "较" + start.AddYears(-1).Year + "年同期增幅" };
      builder.MoveToBookmark("table3");
      Aspose.Words.Tables.Table table = builder.StartTable();//开始画Table
