How to get SharePoint user information from Person or Group field in SharePoint List

Scenario: I have a SharePoint list with various fields. One of them is Person field, in which I am storing the value selected through People Picker. How to get the Person value from this field through SharePoint Object Model.

Approach:


// Step1: Get SharePoint Item object
SPListItem Item = SPContext.Current.Web.Lists["MyList"].Item[0];

// Step2: Get user field object by passing field display name
SPFieldUser userField = (SPFieldUser)Item.Fields.GetField("Created By");

// Step3: Get user field value object
// SPBuiltInFieldId.Author refers to Created By field's internal name
SPFieldUserValue fieldValue = (SPFieldUserValue)userField.GetFieldValue(Item[SPBuiltInFieldId.Author].ToString());

// Step4: Get user object
SPUser userVendor = fieldValue.User;
