c# - 如何使用 FileHelpers 导出到 excel 文件

Question

我正在使用 File Helpers 而且我不确定如何获取我的数据并将其导出到 Excel 文件。

我看到了 extracting records 的教程但不创建 excel 文件。

我试过了

ExcelStorage provider = new ExcelStorage(typeof(Img));

provider.StartRow = 2;
provider.StartColumn = 1;

provider.FileName = "Customers.xls";

provider.HeaderRows = 6;

provider.InsertRecords(imgs.ToArray()); // imgs was a list before

System.IO.FileNotFoundException was unhandled by user code

您需要将 Interop.Excel 和 Interop.Office 引用的“Embed Interop Types”设置为“false”，这将自动将复制本地设置为 true，并且一切正常。
