How to get last inserted id?

I have a table Absences

|  Id  |  Name  |  Job  |
-------------------------
|  1   |  James |   1   |
-------------------------
|  2   |  Simon |   1   |
-------------------------

Where ID is an identity Primary Key incrementing by 1.
I’m accessing this table from a program in C# and I need to do the following :

Insert Into Absences (Name, Job) Values ('aName', 'aJob')

The problem is I need to get the Id column where i’m inserting at the same time because Nameand Job are not unique so I won’t be able to retreive this exact column after.

Is it possible to add a select on the Id column in that query ?

Update

  SqlConnection myConnection = new SqlConnection(@"SomeConnection");
  myConnection.Open();
  SqlCommand myCommand = myConnection.CreateCommand();
  myCommand.CommandText = "Insert Into Absences (Name, Job) Values ('aName', 'aJob')";
  int currentAbs = (int)myCommand.ExecuteScalar();

I get an error on the ExecuteScalar Line. Object reference is not set to and instance of object.

The SQL statement SCOPE_IDENTITY() will give you the value of the identity column of the newly inserted row from within the same scope.

SqlConnection myConnection = new SqlConnection(@"SomeConnection");
myConnection.Open();
SqlCommand myCommand = myConnection.CreateCommand();
myCommand.CommandText = "Insert Into Absences (Name, Job) Values ('aName', 'aJob'); SELECT SCOPE_IDENTITY();";
int currentAbs = (int)myCommand.ExecuteScalar();

Scope Identity Definition
