Hello ,
Question is how to get People Editor Values in Sharepoint, C# ?

Hi,

You can try to use PickerEntity object to retrieve the values from PeopleEditor control.

For example, To get the Email Address use PickerEntity object to retrieve the values from PeopleEditor control.

PickerEntity pckEntity = (PickerEntity)peResponsible.ResolvedEntities[0];
//Here peResponsible is a PeopleEditor Control

string email = pckEntity.EntityData["Email"].ToString();

Reference: PeopleEditor Class. Refer the content under 'Get e-mail address from PeopleEditor PickerEntity' in Community Content section.
