Question

我一直在努力从ASP.Net MVC C＃中的$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1; $cat = ( isset( $_GET['category_select'] ) ) ? $_GET['category_select'] : 1; $args = array ( 'cat' => $cat, 'posts_per_page' => 10, 'paged' => $paged ); $query = new WP_Query( $args ); if( $query->have_posts() ) : while( $query->have_posts() ) : $query->the_post(); echo "-------------------- "; echo " " . the_title(); echo " " . the_category(); endwhile; else: ?> no results found. <?php endif; wp_reset_postdata();?>下载PDF文件。下面的代码工作正常。

对于相同的bytes[]下载过程，我需要将代码转换为.NET Core。

PDF

我试图将以上代码转换为string fileName = "testFile.pdf"; byte[] pdfasBytes = Encoding.ASCII.GetBytes(fileBytes); // Here the fileBytes are already encoded (Encrypt) value. Just convert from string to byte Response.Clear(); MemoryStream ms = new MemoryStream(pdfasBytes); Response.ContentType = "application/pdf"; Response.Headers.Add("content-disposition", "attachment;filename=" + fileName); Response.Buffer = true; ms.WriteTo(Response.OutputStream); Response.Flush(); Response.End();。我收到一个错误： OutputStream 方法不包含此 ms.WriteTo（Response.OutputStream）行的响应。预先谢谢。！

Answer 1

MVC对此进行了简化。您需要做的是返回ActionResult的操作：

public ActionResult GetImage()
{
  string fileName = "testFile.pdf";
  var pdfasBytes = ...;

  return File(pdfasBytes, "application/pdf", fileName);
}
