Power Of Reflection, Generics, Extension Method When Combined

Reflection, Generics, and Extension methods are powerful features but with a little lateral thinking, these can be combined and we can find interesting solutions for problems.
 
Thus, I am here with an interesting piece of code, which combines all the features, mentioned above.
 
While doing coding, we often have to fill List<SelectListItem>. We have to take values from List<T>, extract the values from the selected properties and fill the List<SelectListItem>. 
 
The objective of the piece of coding shown below is to write an extended generic method, which takes a List<T> as an input parameter and also has two more strings, which are property names of the classes and returns List<SelectListItem>
  1. public static class ExtensionMethodClasses  
  2.     {  
  3.         public static List<SelectListItem> GetSelectListItem<T>(this List<T> lstValues, string PropertyText, string PropertyValue)  
  4.         {  
  5.             List<SelectListItem> lstSelectListItem = new List<SelectListItem>();  
  6.             SelectListItem selLstItem;  
  7.             foreach(T t in lstValues)  
  8.             {  
  9.                 selLstItem = new SelectListItem()  
  10.                 {  
  11.                     Text = GetPropValue(t, PropertyText).ToString(),  
  12.                     Value = GetPropValue(t, PropertyValue).ToString()  
  13.                 };  
  14.                 lstSelectListItem.Add(selLstItem);  
  15.             }  
  16.             return lstSelectListItem;  
  17.         }  
  18.   
  19.         public static object GetPropValue(object src, string propName)  
  20.         {  
  21.             return src.GetType().GetProperty(propName).GetValue(src, null);  
  22.         }  
  23.     } 
Thus, the coding is self explanatory.
 
Now, let's look at an example, which uses this piece of coding.
 
The model is shown below.
  1. public class ClassModel  
  2. {  
  3.     public string ClassName { get; set; }  
  4.     public List<StudentModel> students  
  5.     {  
  6.         get  
  7.         {  
  8.             return new List<StudentModel>()  
  9.                 {  
  10.                     new StudentModel()  
  11.                     {  
  12.                         StudentId = 1,  
  13.                         Name = "Name1",  
  14.                         Mark1 = 74.50M  
  15.                     },  
  16.                     new StudentModel()  
  17.                     {  
  18.                         StudentId = 2,  
  19.                         Name = "Name2",  
  20.                         Mark1 = 63.00M  
  21.                     },  
  22.                     new StudentModel()  
  23.                     {  
  24.                         StudentId = 3,  
  25.                         Name = "Name3",  
  26.                         Mark1 = 87.00M  
  27.                     },  
  28.                     new StudentModel()  
  29.                     {  
  30.                         StudentId = 4,  
  31.                         Name = "Name4",  
  32.                         Mark1 = 81.00M  
  33.                     }  
  34.             };  
  35.         }  
  36.     }  
  37. }  
  38.   
  39. public class StudentModel  
  40. {  
  41.     public int StudentId { get; set; }  
  42.     public string Name { get; set; }  
  43.     public decimal Mark1 { get; set; }  
  44. } 
The coding, shown below, uses the method which we created.
  1. ClassModel cm = new ClassModel();  
  2. List<SelectListItem> selLstitem = cm.students.GetSelectListItem("Name", "StudentId");
