在 Blazor 中打印映像

问：

我有一个存储用户数据的 Blazor 服务器应用程序。每个用户都有自己的登录详细信息和登录代码。现在我有一个问题，我想从浏览器输出此代码。我有freeSpire.Barcode库。现在从客户端来看：进入应用程序页面时，我想打印代码，但没有任何反应。这意味着它将应用程序保存在服务器上的文件，但不会打开它。您是否有一种行之有效的方法将文件从客户端打印到服务器？

 public void PrintCodeUser(int  id)
 {

     string imie = "";
     string nazwisko = "";
     string kod = "";
   


     using (SqlConnection con1 = new SqlConnection(connectionToSql))
     {

         string sqll = "  SELECT Imie,Nazwisko FROM CompositeApps.dbo.Kamino WHERE id =" + id;
         try
         {
             var cmdd = new SqlCommand(sqll, con1);
             con1.Open();
             SqlDataReader rdrr = cmdd.ExecuteReader();

             while (rdrr.Read())
             {
                 if ((rdrr.IsDBNull(0))) { imie = "0"; } else { imie = rdrr[0].ToString(); }

                 if ((rdrr.IsDBNull(1))) { nazwisko = ""; } else { nazwisko = rdrr[1].ToString(); }
                 if ((rdrr.IsDBNull(2))) { kod = ""; } else { kod = rdrr[2].ToString(); }



             }

             con1.Close();
