Detailed Reflection->type.system

Reflection first Understand

One: System. Type

Get basic information:

Type.Name//Class name

Type.fullname//full path

Type.namespace//Space name

         Public classStudent { Public intId {Set;Get; }  Public stringName {Set;Get; }  Public intAge {Set;Get; } }        Static voidMain (string[] args) {Student S=NewStudent () {Id =1, Name ="Zzj", age = A }; Type T=typeof(student); //View class InformationConsole.WriteLine ("name={0},fullname={1},namespace={2}", T.name, T.fullname, t.namespace); }

：

Name=student
Fullname=win32. Reflection +student
Namespace=win32

Two. A few important methods under reflection

System.Reflection.

PropertyInfo: Encapsulation Type property Information

ConstructorInfo: Type constructors

MethodInfo: Facet names for types

EventInfo: Type event information

ParameterInfo: Method, constructor information

MemberInfo: Member Type Type.getmembers ()/getmember ()/findmember ()

1. Member Information and MemberInfo

StringBuilder SB =NewStringBuilder (); Memberinfo[] Me= T.getmembers ();//Get page MemberSb. Append ("View Type"+ t.name + t.name +"the member Information"); foreach(MemberInfo minchme) {sb. Append ("member"+m.tostring (). PadRight ( -)+"Type:"+m.membertype+"\ n"); } Console.WriteLine (SB);

2. Field information and FieldInfo type

If you want to get all the fields of a type, you can use the GetFields () method to add a method again
Fieldexplore (): (But the feeling can only get properties, and Static)

        Static voidFieldexplor (Type t) {StringBuilder SB=NewStringBuilder (); Fieldinfo[] Fields=T.getfields (); Sb. Append ("View Type"+ T.name +"the field information: \ n"); Sb. Append (string. Empty.padleft ( -,'-') +"\ n"); foreach(FieldInfo fiinchFields ) {sb. Append ("Name:"+ FI. Name +"\ n"); Sb. Append ("Type:"+ FI. FieldType +"\ n"); Sb. Append ("Features:"+ FI. Attributes +"\ n"); } Console.WriteLine (sb.)        ToString ()); }

To view field information for type student:
--------------------------------------------------
Name: Love
Type: System.String
Features: Public
Name: Lv
Type: System.Int32
Features: Public, Static

3. Attribute information and PropertyInfo type

        Static voidPropertydexplor (Type t) {StringBuilder SB=NewStringBuilder (); Propertyinfo[] Fields=t.getproperties (); Sb. Append ("View Type"+ T.name +"property information for: \ n"); Sb. Append (string. Empty.padleft ( -,'-') +"\ n"); foreach(PropertyInfo fiinchFields ) {sb. Append ("Name:"+ FI. Name +"\ n"); Sb. Append ("Type:"+ FI. PropertyType +"\ n"); Sb. Append ("Readable:"+ FI. CanRead +"\ n"); Sb. Append ("can write:"+ FI. CanWrite +"\ n"); Sb. Append ("Features:"+ FI. Attributes +"\ n"); } Console.WriteLine (sb.)        ToString ()); }

To view property information for type student:
--------------------------------------------------

Readable: True
Writable: True
Feature: None
Names: Name

Writable: True
Feature: None
Name: Age
Type: System.Int32
Readable: True

4. Method information and MethodInfo type

        Static voidMethodexplore (Type t) {StringBuilder SB=NewStringBuilder (); Methodinfo[] Me= T.getmethods ();//Get page MemberSb. Append ("View Type"+ t.name + t.name +"the member Information"); foreach(MethodInfo minchme) {sb. Append ("Name:"+ M.name +"\ n"); Sb. Append ("Signature:"+ m.tostring () +"\ n"); Sb. Append ("Properties:"+ M.attributes +"\ n"); Sb. Append ("return value type:"+ M.returntype +"\ n");        } Console.WriteLine (SB); }
