在新浏览器中打开 PDF 文件 ASP.NET Core 3 中的 window

Question

I have created the pdf file in the MVC Controller in ASP.NET Core 3. I am returning the FileStreamResult from this controller. 我想在新的浏览器 window 中打开 PDF。

下面是 HTML 代码 -

<a asp-controller="Score" asp-action="ViewScore" target="_blank" >View PDF</a>

下面是 controller

public async Task<IActionResult> ViewScore()
{
      /*Created the pdf doc*/
      MemoryStream stream = new MemoryStream();
      stream = doc1.Stream;

      string contentType = "application/pdf";
      string fileName = "sample.pdf";

      var file = File(stream, contentType, fileName);
            
      return file;
}

我正在获取 pdf 文件的下载选项。 取而代之的是，我想在新浏览器 window 中打开 pdf。

如果要在新选项卡中打开 pdf，请不要指定fileDownloadName 。

public async Task<IActionResult> ViewScore()
{
     /*Created the pdf doc*/
     MemoryStream stream = new MemoryStream();
     stream = doc1.Stream;

     string contentType = "application/pdf";
     string fileName = "sample.pdf";

     var file = File(stream, contentType);
        
     return file;
}
