            String Result, URL;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
            ICredentials credentials = new NetworkCredential("username", "Password", "Domain");
            IWebProxy webProxy = new WebProxy("proxy URL", 8080);

Use Crystal Report in C#

Code to view the Crystal Report using C#.

Namespace:

using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;


Code:


            CrystalDecisions.CrystalReports.Engine.ReportDocument oRpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
             CrystalDecisions.Shared.IConnectionInfo conn;


             ConnectionInfo CInfo = new ConnectionInfo();
             CInfo.ServerName = "server";
             CInfo.UserID = "ID";
             CInfo.Password = "Password";

             TableLogOnInfo tableInfo = new TableLogOnInfo();
             tableInfo.ConnectionInfo = CInfo;

             TableLogOnInfos tablelog = new TableLogOnInfos();
             tablelog.Add(tableInfo);

             crystalReportViewer1.ReportSource = Application.StartupPath + "\\Report.rpt";
             crystalReportViewer1.LogOnInfo = tablelog;

             ReportDocument obj = new ReportDocument();
             obj.Load(Application.StartupPath + "\\Report.rpt");

              obj.SetParameterValue("Para1","Value");
             obj.SetParameterValue("Para2", "Value");
           
             crystalReportViewer1.ReportSource = obj;

Start or Stop Services on Remote Machine

Sample code to control the remote machine/system services. Below code shows how to Start or Stop the remote computer service.

Note : To run this code user must have the rights to Start/Stop the service of the remote computer.

Namespace: 
       using System.Management;


Code:

Start service of the Remote Machine:

              try
                {

                    #region Code to start the service
              
                    string serviceName = "Service1";
                    string IP="Remote machine IP";
                    string username ="UserID";
                    string password ="Pass";

                    ConnectionOptions connectoptions = new ConnectionOptions();
                    //connectoptions.Impersonation = ImpersonationLevel.Impersonate;
                    connectoptions.Username = username;
                    connectoptions.Password = pass;

                    //IP Address of the remote machine
                 
                    ManagementScope scope = new ManagementScope(@"\\" + IP + @"\root\cimv2");
                    scope.Options = connectoptions;

                    //WMI query to be executed on the remote machine
                    SelectQuery query = new SelectQuery("select * from Win32_Service where name = '" + serviceName + "'");

                    using (ManagementObjectSearcher searcher = new
                                ManagementObjectSearcher(scope, query))
                    {
                        ManagementObjectCollection collection = searcher.Get();
                        foreach (ManagementObject service in collection)
                        {
                            if (service["Started"].Equals(false))
                            {
                                //Start the service
                                service.InvokeMethod("StartService", null);                             
                            }

                        }
                    }
                  
           #endregion

                }
                catch ()
                {
                 
                }


Similar way you can stop the service of Remote Machine:

                       if (service["Started"].Equals(true))
                        {
                            //Stop the service
                            service.InvokeMethod("StopService", null);                           
                        }

                                doc.SetPageSize(new iTextSharp.text.Rectangle(0, 0, importImage.Width, importImage.Height));
                                doc.SetPageSize(new iTextSharp.text.Rectangle(importImage.Width, importImage.Height));
                                chapter1.Add(importImage);
                                doc.Add(chapter1);
