In this example, we will print "Pass", "Fail" and "On Hold" depending on the 'Result' of the student. We are using a switch case pattern to determine the string. If the Result is 'P' we print 'Pass'; if the Result is 'F' we print 'Fail' else we print 'On Hold' if it is neither 'P' or 'F'.
C#
List<Student> stuList = new List<Student>();
stuList.Add(new Student() { ID = 1, FName = "Shakiy",Result = 'P' });
stuList.Add(new Student() { ID = 2, FName = "Mary", Result = 'P' });
stuList.Add(new Student() { ID = 3, FName = "Bill", Result = 'F' });
stuList.Add(new Student() { ID = 4, FName = "Samantha", Result = 'F' });
stuList.Add(new Student() { ID = 5, FName = "Mary", Result = 'P' });
stuList.Add(new Student() { ID = 6, FName = "John", Result = 'O' });
var slist = from stu in stuList
select new { Name = stu.FName, Result = stu.Result == 'P' ? "Pass" :
stu.Result == 'F' ? "Fail" : "On Hold" };
foreach (var list in slist)
{
// print name and result
}
VB.NET
Dim stuList As New List(Of Student)()
stuList.Add(New Student() With {.ID = 1, .FName = "Shakiy", .Result = "P"c})
stuList.Add(New Student() With {.ID = 2, .FName = "Mary", .Result = "P"c})
stuList.Add(New Student() With {.ID = 3, .FName = "Bill", .Result = "F"c})
stuList.Add(New Student() With {.ID = 4, .FName = "Samantha", .Result = "F"c})
stuList.Add(New Student() With {.ID = 5, .FName = "Mary", .Result = "P"c})
stuList.Add(New Student() With {.ID = 6, .FName = "John", .Result = "O"c})
Dim slist = _
From stu In stuList _
Select New With {Key .Name = stu.FName, Key .Result = If(stu.Result = "P"c, "Pass", If(stu.Result = "F"c, "Fail", "On Hold"))}
For Each list In slist
' print name and result
Next list
