        permissionPplPicker.MultiSelect = true;  
        permissionPplPicker.AllowEmpty = false;  
        permissionPplPicker.AutoPostBack = true;

        this.Controls.Add(styleControl);  
        this.Controls.Add(permissionPplPicker);  
      } 

Create People picker SharePoint Application page .aspx Page ,

<table style="MARGIN-TOP: 8px" class='ms-formtable' border='0' cellspacing='0' cellpadding='0' width="100%">  
                   <tr>  
         <td class='ms-formlabel' valign='top' width='190' nowrap>  
           <h3 class='ms-standardheader'>  
             <nobr>People picker control<span class='ms-formvalidation' title="This is Required filed."> *</span></nobr>  
           </h3>  
         </td>  
         <td class='ms-formbody' valign='top'><span dir='none'>  
           <SharePoint:PeopleEditor ID=" pplPicker " runat="server" AutoPostBack="false" MultiSelect="false" MaximumEntities="1" ValidatorEnabled="true" SelectionSet="User" CssClass="ms-long" Width="99%" EnableViewState="true" />  
           <SharePoint:InputFormRequiredFieldValidator ID="ADValidator" runat="server" Display="Dynamic" SetFocusOnError="true"  
             ControlToValidate="pplPicker" BreakBefore="true" ErrorMessage="You must specify a value for this required field." />  
         </span></td>  
       </tr></table> 

Get SPUser or SharePoint web user from People picker Programmatically C#

Code:

SPUser oUser = null;

if (pplPicker.Entities.Count > 0)
     {
        PickerEntity ppl = (PickerEntity) pplPicker.Entities[0];
        oUser = SPContext.Current.Web.EnsureUser(ppl.DisplayText);
      }

For more than one User we can iterate pplPicker.Entities collection in foreach loop.

Or you can use ResolvedEntities in place of .Entities

Save or update people picker User / SPUser programmatically in/to SharePoint List Item

Code:

using (SPSite oSite = new SPSite(SPContext.Current.Site.Url))
    {
      using (SPWeb oWeb = oSite.OpenWeb("//Site Relative Url//", false))
        {
  try
   {
    /*Getting Item by List Item ID and saving User to the list */
    SPListItem user = oWeb.Lists["User List"].GetItemById(Convert.ToInt32(ItemID))

    /* oUsercan be get from people picker by referring above code*/
    user["Team Lead"] = oUser;
    adminWeb.AllowUnsafeUpdates = true;
    user.Update();
   }
  catch(SPException ex){ }
  finally
  {
   adminWeb.AllowUnsafeUpdates = false;
   adminWeb.Dispose();
  }
  }
 }

Get SharePoint user / SPUser from SharePoint List using C# / Programmatically

Code:

/* Calling GetSPUserMethod to get User from List*/

SPListItem oItem = oWeb.Lists["User List"].GetItemById(Convert.ToInt32(ItemID));
SPUser oUser = GetSPUser(oItem, "User");
protected SPUser GetSPUser(SPListItem item, string user)
        {
            SPUser oUser = null;
            SPFieldUserValue userValue = new SPFieldUserValue(item.Web, Convert.ToString(item[user]));

            if (userValue != null)
            {
                oUser = userValue.User;
            }
            return oUser;
        }
