Upload Documents To Server From Windows Application or Another Application Using WCF

Upload Documents To Server From Windows Application Using WCF

Requirement : A WCF Service in a web application ,windows application 

First take a web application and add  a WCF Web service .
Name of the service is UploadPdf.svc
Property Class is RemoteFileInfo.cs
Now write the following code into the inter face IUploadPdf.cs:


using System;
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
 public interface IUploadPdf
{

    [OperationContract()]
    Int16 UploadFile(RemoteFileInfo request);

}

Now Implemented Class Name UploadPdf.cs  code details :("Pdf_Documents" this folder should be on the application path)

using System;
using System.Collections.Generic;
using System.IO;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.Text;
using System.Web.Hosting;


// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "UploadPdf" in code, svc and config file together.
public  class UploadPdf : IUploadPdf
{

    short IUploadPdf.UploadFile(RemoteFileInfo request)
    {
        try
        {
            String filename = "";
            String filePath = "";
            filename = request.FileName;
            filePath = Path.Combine(HostingEnvironment.ApplicationPhysicalPath, "Pdf_Documents");
            File.WriteAllBytes(filePath + "\\" + request.FileName, request.FileByteStream);
            if (File.Exists(filePath + "\\" + request.FileName))
            {
                return 1;
            }
            else
            {
                return 0;
            }
           
        }
        catch (Exception )
        {
       
        throw new NotImplementedException();
        }

    }
Now the property class RemoteFileInfo.cs code is as follows :


using System;
using System.Collections.Generic;
using System.ServiceModel;
using System.Web;

/// <summary>
/// Summary description for RemoteFileInfo
/// </summary>
public class RemoteFileInfo
{
  

   
        [MessageHeader(MustUnderstand = true)]
        public string FileName;

        [MessageHeader(MustUnderstand = true)]
        public long Length;

        [MessageBodyMember(Order = 1)]
        public byte[] FileByteStream;

    }

Web,config file should be :
<?xml version="1.0"?>
<configuration>
  <system.serviceModel>

  
    <bindings >
     
       <basicHttpBinding>
      <binding name="BasicHttpBinding_Upload" closeTimeout="00:10:00"
       openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
       allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
       maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
       messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
       useDefaultWebProxy="true">
        <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647"
         maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
        <security mode="None">
          <transport clientCredentialType="None" proxyCredentialType="None"
           realm="" />
          <message clientCredentialType="UserName" algorithmSuite="Default" />
        </security>
      </binding>
    </basicHttpBinding>
     
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services >
     
      <service name="UploadPdf" >
      <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_Upload"
   contract="IUploadPdf"/>
    </service>
    </services>
   
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
  </system.serviceModel>
  <system.web>
    <compilation debug="true"/>
  </system.web>
</configuration>



Now Create a windows application and add WCF service to this project  and on page load write the following code place a pdf file on debug folder :
 SRUP is the Service Reference name
Imports System.IO

Public Class Form1
    Dim objup As New SRUP.UploadPdfClient()
    Dim objfile As New SRUP.RemoteFileInfo()
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
       
        Dim fileList As IList = New ArrayList()
        Dim fileEntries As String() = Directory.GetFileSystemEntries("D:\MergePdf")
        Dim extntion As String
        Dim fileNm As String
        For Each fileNm In fileEntries
            objfile.FileName = Path.GetFileName(fileNm)
            extntion = Path.GetExtension(fileNm)
            If extntion = ".pdf" Then
                objfile.FileByteStream = GetBytesFromUrl(fileNm)
                objup.UploadFile(objfile)
            End If

        Next


    End Sub

    Public Shared Function GetBytesFromUrl(ImageFilePath As String) As Byte()

        Dim _tempByte As Byte() = Nothing
        If String.IsNullOrEmpty(ImageFilePath) = True Then
            Throw New ArgumentNullException("Image File Name Cannot be Null or Empty", "ImageFilePath")
            Return Nothing
        End If
        Try
            Dim _fileInfo As New System.IO.FileInfo(ImageFilePath)
            Dim _NumBytes As Long = _fileInfo.Length
            Dim _FStream As New System.IO.FileStream(ImageFilePath, System.IO.FileMode.Open, System.IO.FileAccess.Read)
            Dim _BinaryReader As New System.IO.BinaryReader(_FStream)
            _tempByte = _BinaryReader.ReadBytes(Convert.ToInt32(_NumBytes))
            _fileInfo = Nothing
            _NumBytes = 0
            _FStream.Close()
            _FStream.Dispose()
            _BinaryReader.Close()
            Return _tempByte
        Catch ex As Exception
            '#########
            Throw ex
            '#########
            Return Nothing
        End Try
    End Function


Now app.config file would be like that :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IUploadPdf" />
            </basicHttpBinding>
        </bindings>

        <client>
            <endpoint address="Service hosted address"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IUploadPdf"
                contract="SRUP.IUploadPdf" name="BasicHttpBinding_IUploadPdf" />
        </client>
    </system.serviceModel>
</configuration>
