Application:

This application contains an example of using the Rotativa.AspNetCore library, which converts a static view or a view with dynamic data into .pdf.

Frameworks:

• .Net Core 2.1
• .Net Core 3.1
• .Net 5
• .Net 6

---

Libraries (only most important):

• Bootstrap
• Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation
• Rotativa.AspNetCore

---

How to configure and use:

1. Create an Asp.Net Core Web Project

2. Download the Rotativa.AspNetCore package via NuGet

3. Create a folder in wwwroot called rotativa-aspnetcore

4. Copy the following files to the folder:

   • help-wkhtmltoimage.txt
   • help-wkhtmltopdf.txt
   • wkhtmltoimage.exe
   • wkhtmltopdf.exe

5. Observation: For each version of .Net an MVC and Environment configuration must be used.

   In the Startup.cs file, add in the Configure method, the line of code:

   RotativaConfiguration.Setup(env.WebRootPath, @"lib/rotativa-aspnetcore");

   For example:

   public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
   {
       if (env.IsDevelopment())
       {
           app.UseDeveloperExceptionPage();
       }
       else
       {
           app.UseExceptionHandler("/Home/Error");
           app.UseHsts();
       }
   
       app.UseHttpsRedirection();
       app.UseStaticFiles();
   
       app.UseRouting();
   
       app.UseAuthorization();
   
       app.UseEndpoints(endpoints =>
       {
           endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}/{id?}");
       });
   
       RotativaConfiguration.Setup(env.WebRootPath, @"lib/rotativa-aspnetcore");
   }

6. In the Controller, use the ViewAsPdf() command to generate the .pdf from a view, passing the view and an object as parameters if necessary.

   public IActionResult Index()
   {
       List<Client> clients = new List<Client>()
       {
           new Client(){ Cpf="127.256.369.35", Name="Lucas Santos", Gender="Male", Age=23, Telephone="3841-3856" },
           new Client(){ Cpf="185.989.636.85", Name="Júlia Almeida", Gender="Female", Age=13, Telephone="3142-3885" },
           new Client(){ Cpf="589.245.854.14", Name="Carlos Cesar", Gender="Male", Age=35, Telephone="3885-1212" },
           new Client(){ Cpf="753.357.147.25", Name="Altair Silva", Gender="Male", Age=58, Telephone="3696-1296" },
           new Client(){ Cpf="441.258.369.85", Name="Ana Clara", Gender="Female", Age=21, Telephone="3758-4745" },
           new Client(){ Cpf="758.969.354.14", Name="Lara Magalhães", Gender="Female", Age=18, Telephone="3996-6658" },
           new Client(){ Cpf="894.758.263.21", Name="Ronaldo Santos", Gender="Male", Age=40, Telephone="3745-7585" },
           new Client(){ Cpf="141.456.251.32", Name="Marcus Vinícius", Gender="Male", Age=32, Telephone="3442-3365" }
       };
   
       return new ViewAsPdf("Index", clients);
   }
