C # Dynamic types and anonymous classes

Dynamic type
Simple example

Dynamic New // dynamic type fields are readable and writable 1  "Test"; string json = Utils.ConvertJson.JsonEncode (expando);  // Output {id:1,name: ' Test '}

Adding fields dynamically

list<string> FieldList =Newlist<string> () {"Name"," Age","Sex"};//From config or dbDynamicDobj =NewSystem.Dynamic.ExpandoObject ();varDIC = (idictionary<string,Object>) Dobj;foreach(varFielditeminchFieldList) {Dic[fielditem]="Set"+fielditem+"value";/*realize the function of dynamic adding property like js var obj={};                                                                        var field= "Id"; Eval ("obj."                                                                        +field+ "= 1"); Alert (obj. ID); 1*/}varval = dobj. Name;//"Set Name value"varVal1=dobj. Age;//"Set age value"

Enumerates all members of the object

foreach(varFielditeminch(Idictionary<string, object>) {dobj) {varv = (Fielditem.key +": "+fielditem.value);} Anonymous class//var aaaa = new {id=1,name= "Test"};//anonymous class fields are read-only and not writableDynamicAAAA =New{id=1, name="Test"};//anonymous class fields are read-only and not writableAaaa. Id =2;//non-writable error cannot be a property or indexer "<>F__ANONYMOUSTYPE1<INT>. Id "Assignment-it is read-only Dynamicobj = Newtonsoft.Json.JsonConvert.DeserializeObject ("{Name: ' AA ', Sex: ' Male ', age:11}");varname = obj. Name.value;//AA
