C # uses reflection to replicate the value of the same property between objects of two classes

http://blog.csdn.net/u013093547/article/details/53584591

Today, when copying objects, looking at the code is a bit annoying, a bunch of code, or looking for a direct reflection copy of the same property values of different objects

Baidu a bit, the result of the second blog is that the address is the top link address

The main one is the following code.

1  /// <summary>2         ///Pass in object B of type B, assigning a value of the same name as B to a created3         /// </summary>4         /// <typeparam name= "A" >Type a</typeparam>5         /// <typeparam name= "B" >Type B</typeparam>6         /// <param name= "B" >parameter B of type B</param>7         /// <returns>copy a of the value of the same property in B</returns>8          Public StaticA Mapper<a, b>(b b)9         {TenA = activator.createinstance<a>(); One             Try A             { -Type TypeB = B.gettype ();//Get Type -Type TypeA =typeof(A); the                 foreach(PropertyInfo SPinchTypeb.getproperties ())//Get property fields of type -                 { -                     foreach(PropertyInfo APinchtypea.getproperties ()) -                     { +                         if(AP. Name = = sp. Name)//determine if property names are the same -                         { +Ap. SetValue (A, sp.) GetValue (b,NULL),NULL);//gets the value of the B object property copied to the property of the A object A                         } at                     } -                 } -             } -             Catch(Exception ex) -             { -                 Throwex; in             } -             returnA; to}

Create a copy b

1 /// <summary>2         ///Object A of type A, object B of type B, assigns values of the same name B and a to a3         /// </summary>4         /// <typeparam name= "A" ></typeparam>5         /// <typeparam name= "B" ></typeparam>6         /// <param name= "a" ></param>7         /// <param name= "B" ></param>8          Public Static voidMapper<a, b> (b b,refa A)9         {Ten             Try One             { AType TypeB = B.gettype ();//Get Type -Type TypeA =typeof(A); -                 foreach(PropertyInfo SPinchTypeb.getproperties ())//Get property fields of type the                 { -                     foreach(PropertyInfo APinchtypea.getproperties ()) -                     { -                         if(AP. Name = = sp. Name)//determine if property names are the same +                         { -Ap. SetValue (A, sp.) GetValue (b,NULL),NULL);//gets the value of the B object property copied to the property of the A object +                         } A                     } at                 } -             } -             Catch(Exception ex) -             { -                 Throwex; -             } in}

incoming a copy b
