C# 使用.NET 4.6 Web API和React.js上传Excel文件

在从前端选择.NETWebAPI控制器后，我尝试读取.NETWebAPI控制器中的Excel文件列和行，该前端是React。我能够从前端选择一个文件，并在控制器中接收字节数组。我的问题是如何将二进制形式的excel文件解析为C对象？我的目标是在不保存文件的情况下读取行和列

我尝试使用EPPlus库将字节数组转换为ExcelPackage，但似乎不起作用

.NETAPI控制器

[Route("UploadFile")]
[HttpPost]
public async Task<IHttpActionResult> UploadFile()
{
    ExcelPackage set = new ExcelPackage();
    var filesReadToProvider = await Request.Content.ReadAsMultipartAsync();
    foreach (var stream in filesReadToProvider.Contents)
    {

        Byte[] fileBytes = await stream.ReadAsByteArrayAsync();

        set = ByteArrayToObject(fileBytes);
        var fileName = stream.Headers.ContentDisposition.FileName;
        var contentType = stream.Headers.ContentType.MediaType;
    }
    return StatusCode(HttpStatusCode.OK);

}
private ExcelPackage ByteArrayToObject(byte[] arrBytes)
{
    using (MemoryStream memStream = new MemoryStream(arrBytes))
    {
        ExcelPackage package = new ExcelPackage(memStream);
        var workSheet = package.Workbook.Worksheets["work book"];
        return package;
    }
}
