C# 将整个数据集转换为Excel，并使用EPPlus c将其存储在Azure blob中

我使用了下面的代码来生成excel，但如何将此excel传递给blob

                    using (DataSet ds = finalDataSetOutput)
                    {
                        if (ds != null && ds.Tables.Count > 0)
                        {
                            using (ExcelPackage pck = new ExcelPackage())
                            {
                          foreach (DataTable dt in ds.Tables)
                            {
                                    ExcelWorksheet ws = pck.Workbook.Worksheets.Add(dt.TableName);
                                ws.Cells["A1"].LoadFromDataTable(dt, true);
                                    int i = 1;
                                    foreach (DataColumn dc in dt.Columns)
                                    {
                                        i++;
                                        if (dc.DataType == typeof(decimal))
                                            ws.Column(i).Style.Numberformat.Format = "#0.00";
                                    }

                                }
                                pck.SaveAs(new FileInfo(@"D:\SampleExcels\NewFile.xlsx"));

                            }

                        }
                    }

如何创建excel并存储在azure blob中。

我最近做了类似的事情，尽管我使用azure函数从集合而不是数据集填充excel数据。原理应该是一样的-只需连接到Blob容器并创建一个新的CloudBlockBlob：

注意：使用System.ComponentModel.Description装饰器将允许您在输出Excel中具有列标题。详情如下：

[FunctionName("WriteExcelToBlob")]
public async Task Run(
    [TimerTrigger("*/30 * * * * *")] TimerInfo timer,
    [Blob("excelFiles", FileAccess.Write, Connection = "Storage")] CloudBlobContainer blobContainer,
    ILogger log
)
{
    var fileNameSuffix = DateTime.Now.ToString("yyyyMMdd_HHmmss");

    var myCollection = new List<MyObject>();

    var newBlobName = $"myFile_{fileNameSuffix}.xlsx";
    var newBlob = blobContainer.GetBlockBlobReference(newBlobName);

    using (var excel = new ExcelPackage())
    {
        var worksheet = excel.Workbook.Worksheets.Add("My Worksheet");
        worksheet.Cells.LoadFromCollection(myCollection);

        using (var stream = await newBlob.OpenWriteAsync())
        {
            excel.SaveAs(stream);
        }
    }
}

using System.ComponentModel;

public class MyObject
{
    [Description("Name")]
    public string Name { get; set; }
    [Description("Home Address")]
    public string HomeAddress { get; set; }
}
