  Hello,

  I want to upload files with more than 1GB. I already change the maxAllowedContentLength="4294967295" to allow bigger files and the maxRequestLength="2147483647", but nothing seems to work. I already change the limits in IIS, but still, doesn't work. The max value that I was able to send was 40M.

  My code:

  using System;
  using System.Collections.Generic;
  using System.Diagnostics;
  using System.IO;
  using System.Linq;
  using System.Security.Cryptography;
  using System.Web;
  using System.Web.Services;
  
  namespace Ctrldocphc
  {
      /// <summary>
      /// Summary description for index
      /// </summary>
      [WebService(Namespace = "http://tempuri.org/")]
      [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
      [System.ComponentModel.ToolboxItem(false)]
      // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
      // [System.Web.Script.Services.ScriptService]
      public class index : System.Web.Services.WebService
      {
  
          [WebMethod]
          public string HelloWorld()
          {
              return "Hello World";
          }
  
          [WebMethod]
          public string CopiarFicheiro2(string ficheiro, string nomeNovo, string destino)
          {
              if (!Directory.Exists(destino))
              {
                  Directory.CreateDirectory(@"" + destino);
              }
              byte[] byt = Convert.FromBase64String(ficheiro);
              File.WriteAllBytes(@"" + destino + nomeNovo, byt);
              return "true";
          }
  
          [WebMethod]
          public string CopiarFicheiro_20MB(string ficheiro, string nomeNovo, string destino)
          {
              if (!Directory.Exists(destino))
              {
                  Directory.CreateDirectory(@"" + destino);
              }
              byte[] docbinaryarray = Convert.FromBase64String(ficheiro);
            // string strdocPath = Path.Combine(@"" + destino, nomeNovo);
  
  
              FileStream objfilestream = new FileStream(@"" + destino+nomeNovo, FileMode.Create, FileAccess.ReadWrite);
              objfilestream.Write(docbinaryarray, 0, docbinaryarray.Length);
              objfilestream.Close();
  
             
  
              return "true";
          }
  
          [WebMethod]
          public string CopiarFicheiro(string ficheiro, string nomeNovo, string destino)
          {
              string _return = "true";
              if (!Directory.Exists(destino))
              {
                  Directory.CreateDirectory(@"" + destino);
              }
              byte[] docbinaryarray = Convert.FromBase64String(ficheiro);
             
  
  
              using (FileStream fs = new FileStream(
                  @"" + destino + nomeNovo,  // name of file
                  FileMode.Create,    // create or overwrite existing file
                  FileAccess.Write   // write-only access
                  ))
              {
                  for (int i = 0; i < docbinaryarray.Length; i++)
                  {
                      fs.WriteByte(docbinaryarray[i]);
                  }
  
  
                
              }
  
             
                  return _return;
          }
  
  
  
  
      }
  
  
  }
  

  
  Any configuration to iis to allow me to send larger files ?
