How to: Converting List Item to SPUser object..?

Hi All,

Many times we need to cast a list item to a SPUser object. It can easily done using these steps:

Step1: Get the current item

SPListItem currentItem = properties.ListItem;

Step2: Get the value display name of the current logged in user and Created by Field of the current item

currentUser = currentItem["Author"].ToString();

Step3: Get the user id as integer
int userid = Convert.ToInt32(currentUser.Substring(0, currentUser.IndexOf(";#")));

Step4: Convert SharePoint user which matches the ID
SPUser user = currentTeamSite.AllUsers.GetByID(userid);

There is one more case where we have number of users. In this scenario,

we can loop the users:

--------------------------------------------------------------------------------

// get a reference to the "Alerts" list as an instance
SPList alerts = spWebRoot.Lists["Checklists Alerts"];

// get the query object for user alert
SPQuery queryUserAlert = new SPQuery();

queryUserAlert.Query = "" +
"" +
"" +
"" + teamName + "" +
"" +
"";

SPListItemCollection noOfUsers = alerts.GetItems(queryUserAlert);

//Get all the users in that team (such as Desktop Support - Daily)
foreach (SPListItem item in noOfUsers)
{
//Use "GetUser" function for List "item" into a SPUser ojbect
SPUser user = GetUser(item, item.Fields["User"]);

// REMAINING LOGIC

}

private SPUser GetUser(SPListItem item, SPField userField)
{
string currentValue = item[userField.Title].ToString();
SPFieldUser field = (SPFieldUser)userField;
SPFieldUserValue fieldValue = (SPFieldUserValue)field.GetFieldValue(currentValue);
return fieldValue.User;

}

Happy Coding,

Cheers
