.net - Populate Class from List of Objects C# -

first off hope can describe looking if not clear please let me know , try best clarify.

i have 2 classes 1 being small class gets wrapped list. second class uses values list. here examples of classes.

class firstclass {      public string value1 {get; set; }     public string value2 {get; set; }     public string value3 {get; set; }     public string value4 {get; set; }     public string value5 {get; set; }     public string value6 {get; set; } }  class secondclass {     public string fieldname { get; set; }     public string fieldvalue { get; set; } }   list<secondclass> sc = new list<secondclass>();  sc[0].fieldname = "value1"; sc[0].fieldvalue = "hello world"; sc[1].fieldname = "value2"; sc[1].fieldvalue = "hello world"; sc[2].fieldname = "value3"; sc[2].fieldvalue = "hello world"; sc[3].fieldname = "value4"; sc[3].fieldvalue = "hello world"; sc[4].fieldname = "value5"; sc[4].fieldvalue = "hello world"; sc[5].fieldname = "value6"; sc[5].fieldvalue = "hello world"; 

okay see 2 classes there , see how secondclass list has 2 values each object first 1 being name of field matches name of field in firstclass , value want apply corresponding field in firstclass.

so how transfer values 1 other? god hope cleared , did not make confusing.

so think have better way explain using information above.

the secondclass object in index 2

sc[2].fieldname = "value3"; sc[2].fieldvalue = "hello world"; 

needs assigned firstclass

so sc[2].fieldname = "value3"; in firstclass actual field named value3 need assign value of sc[2].fieldvalue = "hello world"; firstclass field value3

hopefully cleared bit.

i think need use reflection accomplish goal...i.e. typeof(firstclass).getproperties

in static constructor of firstclass use reflection dictionary of propertyinfo instances. once , cache performance reasons. when call method setvaluebyreflection looks proposed string value of property in dictionary , sets value.

internal class program {     private static void main(string[] args)     {         list<secondclass> secondclasses = new list<secondclass>();          secondclasses.add(new secondclass { fieldname = "value1", fieldvalue = "hello world 1" });         secondclasses.add(new secondclass { fieldname = "value2", fieldvalue = "hello world 2" });         secondclasses.add(new secondclass { fieldname = "value3", fieldvalue = "hello world 3" });         secondclasses.add(new secondclass { fieldname = "value4", fieldvalue = "hello world 4" });         secondclasses.add(new secondclass { fieldname = "value5", fieldvalue = "hello world 5" });         secondclasses.add(new secondclass { fieldname = "value6", fieldvalue = "hello world 6" });         // secondclasses.add(new secondclass { fieldname = "value7", fieldvalue = "hello world 7" }); // line throw exception          firstclass fc = new firstclass();          foreach (secondclass secondclass in secondclasses)         {             fc.setvaluebyreflection(secondclass.fieldname, secondclass.fieldvalue);         }     } }  class firstclass {     private static readonly dictionary<string, propertyinfo> _publicproperties;      static firstclass()     {         const bindingflags bindingflags = bindingflags.instance | bindingflags.declaredonly | bindingflags.public | bindingflags.setproperty;          _publicproperties = typeof(firstclass).getproperties(bindingflags).todictionary(propertyinfo => propertyinfo.name);     }      public string value1 { get; set; }     public string value2 { get; set; }     public string value3 { get; set; }     public string value4 { get; set; }     public string value5 { get; set; }     public string value6 { get; set; }      /// <summary>     /// sets value of 1 of properties of class specified propertyname parameter.     /// </summary>     /// <exception cref="argumentexception">thrown when propertyname not valid property of firstclass.</exception>     public void setvaluebyreflection(string propertyname, string value)     {         propertyinfo propertyinfo;         _publicproperties.trygetvalue(propertyname, out propertyinfo);          if (propertyinfo != null)         {             propertyinfo.setvalue(this, value, null);         }         else         {             throw new argumentexception("firstclass not contain property of name " + propertyname, "propertyname");         }     } }  class secondclass {     public string fieldname { get; set; }     public string fieldvalue { get; set; } }
