By reflection, into the data array specified in the class object

Friend encountered a problem:

Read from the character string in the text ( "San", "20" ...), a string of known type ( "string", "int" ....)

Converted into the desired class object.

The data is large, frequent use may affect the efficiency of reflection, so a small demo written as follows:

Person class:

. 1  class the Person
 2      {
 . 3          public  String XM { GET ; SET ;}
 . 4          public  int NL { GET ; SET ;}
 . 5          public  void ShowMe ()
 . 6          {
 . 7              Console.WriteLine ( " I " + XM + " , I am ." + NL + " years old. " );
 8          }
 9      }

Conversion helper class:

class Convert_Helper 
    { 
        static PropertyInfo [] PS;
         // fed type, all public properties of the reflective back 
        public  static  void get_Props <T> (T TT) 
        { 
            PS = tt.GetType () GetProperties ();. 
        } 
        // into character string and type, type of return value of the specified 
        public  static  Dynamic change_Type ( String X, String x_type) 
        { 
            IF (x_type == " int " ) 
            { 
                return  int .Parse (X); 
            } 
            returnX; 
        } 

        // into objects, and type of the assigned object. 
        public  static  void get_object ( Dynamic obj, String [] MyValues, String [] ValueType) 
        { 
            for ( int I = 0 ; I <myvalues.Length; I ++ ) 
            { 
                PS [I] .setValue (obj, change_Type (MyValues [I] , ValueType [I]), null ); 
            } 
        } 
    }

The main program:

 1 static void Main(string[] args)
 2         {
 3             string[] v1,t1;
 4             List<Person> mylist=new List<Person>();
 5             Person t;
 6             Convert_Helper.get_Props(new Person());
 7 
 8             t = new Person();
 9             v1=new string[2]{"张三","20"};
10             t1 = new string[2] { "string", "int" };
11             Convert_Helper.get_Object(t,v1,t1);
12             mylist.Add(t);
13 
14             t = new Person();
15             v1 = new string[2] { "李四", "18" };
16             t1 = new string[2] { "string", "int" };
17             Convert_Helper.get_Object(t, v1, t1);
18             mylist.Add(t);
19 
20             foreach (var item in mylist)
21             {
22                 item.showme();
23             }
24             Console.ReadKey();
25         }

This, even if the text is a two-dimensional array or other bulk form, slightly modified main routine; if the attribute does not correspond to get_Props method slightly modified.

Readers should not be difficult yourself.
