Question

有人能指出我正确的方向吗？我不是非常熟悉.NET或Javascript，所以这对我来说有点太难了。让用户以Excel电子表格的形式下载Javascript array对象的最简单方法是什么？我知道将其导出为CSV是最简单的方法，但我真的需要以适当的.xlsx格式导出它。据我了解，我将需要使用OpenXML sdk，但没有太多关于如何实际接近它的信息（至少是noob友好信息）。任何帮助表示赞赏。

Answer 1

您还可以输出基本HTML表并设置相应的响应标头（Content-type）：

应用/ vnd.openxmlformats-officedocument.spreadsheetml.sheet

这将提示用户打开Excel以查看文件。

$("[id$=myButtonControlID]").click(function(e) {
    window.open('data:application/vnd.ms-excel,' + encodeURIComponent( $('div[id$=divTableDataHolder]').html()));
    e.preventDefault();
});

table
{
    border: 1px solid black;    
}
th
{
    border: 1px solid black;
    padding: 5px;

<button id="myButtonControlID">Export Table data into Excel</button>
<div id="divTableDataHolder">
<table>
    <tr><th>ColumnOne </th><th>ColumnTwo</th></tr>
<tr>
<td>row1ColValue1</td><td>row1ColValue2</td>
</tr>
<tr>
<td>row2ColValue1</td><td>row2ColValue2</td>

</table>
</div>

Folloiwng是ASP.Net MVC中的ClosedXML方法。它有助于将文件下载为xlsx

<强> GenerateExcelInvoiceController

    private void GenerateExcelInvoiceController(ClosedXML.Excel.XLWorkbook workBook, string formtFileName)
    {

        string currentTime = DateTime.Now.ToString();

        string headerString = formtFileName.Replace("{0}", currentTime);
        headerString = headerString.Replace(" ", "");
        Response.Clear();
        Response.Buffer = true;
        Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
        Response.AddHeader("content-disposition", headerString);
        using (MemoryStream memoryStream = new MemoryStream())
        {
            workBook.SaveAs(memoryStream);
            memoryStream.WriteTo(Response.OutputStream);
            memoryStream.Close();
        }
        Response.End();
    }

ClosedXML.Excel.XLWorkbook GetWorkBook

    public static ClosedXML.Excel.XLWorkbook GetWorkBook(DataTable table, string sheetName)
    {
        ClosedXML.Excel.XLWorkbook workBook = new ClosedXML.Excel.XLWorkbook();
        ClosedXML.Excel.IXLWorksheet workSheet = workBook.Worksheets.Add(table, sheetName);
        return workBook;
    }

POST的控制器操作

    [Authorize]
    [HttpPost]
    public void PracticeList(BalanceStatementModel modelReceived)
    {

        List<FinanceEntity> rows = GetRunningBalanceDueForPractice();

        DataTable table = new DataTable();
        using (var reader = FastMember.ObjectReader.Create(rows, "ItemDescription", "EventDate", "Amount", "RunningBalanceDue"))
        {
            table.Load(reader);
        }

        ClosedXML.Excel.XLWorkbook workBook =  CommonBusinessMethodHelpers.GetWorkBook(table, "Statement");
        string formtFileName = "attachment;filename=\"BalanceStatement-{0}.xlsx\"";
        GenerateExcelInvoiceController(workBook, formtFileName);


    }

注意：它使用NuGet提供的FastMember librabry。
