Asp.Net核心:通过客户端浏览器的URL下载PDF格式的SSRS报告

我有一个SSRS报告URL,如果我在浏览器中输入该URL,它会显示带有打印和保存选项的SSRS报告,如:

我想要的是,上面有一个按钮 .cshtml 所以点击那个按钮我需要在客户端浏览器上下载报告。

网址: http://xyz/ReportS/report/UAT/SampleReport_V1?Srno=X123

我尝试的是:

通过设置 &rs:Format=PDF 并从Asp.Net核心应用程序,但它生成了PDF,但格式已损坏。

代码:

public void Download_SSRSInPDF()
{
    string URL = "http://xyz/ReportS/report/UAT/SampleReport_V1";
    string Command = "Render";
    string Format = "PDF";
    URL = URL + "?SrNo=X123&rs:Command=" + Command + "&rs:Format=" + Format;
    System.Net.HttpWebRequest Req = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(URL);

    Req.Credentials = System.Net.CredentialCache.DefaultCredentials;
    Req.Method = "GET";
    string path = @"E:\New folder\Test.pdf";
    System.Net.WebResponse objResponse = Req.GetResponse();
    System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Create);
    System.IO.Stream stream = objResponse.GetResponseStream();
    byte[] buf = new byte[1024];
    int len = stream.Read(buf, 0, 1024);

    while (len > 0)
    {
        fs.Write(buf, 0, len);
        len = stream.Read(buf, 0, 1024);
    }
    stream.Close();
    fs.Close();
}

怎么做呢Asp.Net核心?
