Getting the User profile

Note : Got the code while search for User profile in Net. I have changed only the Red Line because the code I got, was getting the context as null.

private UserProfile GetUserInfo(string AccountName)

{

UserProfile profile = null;

SPServiceContext serviceContext = SPServiceContext.GetContext(SPContext.Current.Site);

UserProfileManager profileManager = new UserProfileManager(serviceContext);

if (AccountName != string.Empty)

{

profile = profileManager.GetUserProfile(AccountName);

}

else

{

profile = profileManager.GetUserProfile(SPContext.Current.Web.CurrentUser.RawSid);

}

return profile;

}

Retrieving Picture URL or User Info from sharepoint webservices

First add the web reference to the userprofileservice.asmx

http://serverURL/_vti_bin/userprofileservice.asmx

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;
using System.Net;
using ConsoleApplicationSharepointTesting.WebServiceMyReference; (Name of the Web reference)

namespace ConsoleApplicationSharepointTesting
{
class Program
{
static void Main(string[] args)
{
PropertyData[] userDetails;
UserProfileService userprof = new UserProfileService();
SPSecurity.RunWithElevatedPrivileges(delegate()
{

userprof.PreAuthenticate = true;
userprof.Credentials = new NetworkCredential("UserName", "Password", "Doamin");
userDetails = userprof.GetUserProfileByName("Domain\UserName");

if (userDetails != null)
{

Console.WriteLine(userDetails[15].Name + " Path of the Image -------" + userDetails[15].Values[0].Value.ToString());

}

Console.Read();
});

Where index 15 refers to the PictureURL

2 refers to the FirstName
4 refers to the LastName

For NetworkCredential(....) use System.Net Namespace

By using foreach loop we can get all the details of the user.
kindly do check in the loop

userDetails[Index].Values have a value, otherwise we will be getting the index out of range runtime error.
