FieldBuilder.ReflectedType Property

Indicates the reference to the Type object from which this object was obtained. This property is read-only.

Namespace:  System.Reflection.Emit
Assembly:  mscorlib (in mscorlib.dll)

public override Type ReflectedType { get; }

Property Value

Type: System.Type
A reference to the Type object from which this instance was obtained.



A FieldBuilder object represents a field of a particular class. In order to obtain a FieldBuilder object, the Type object that represents the class that supports the field is queried. This property holds a reference to that Type object.

The following code sample illustrates the use of ReflectedType.

using System;
using System.Threading;
using System.Reflection;
using System.Reflection.Emit;
using System.Security.Permissions;

public class FieldBuilder_Sample
   private static Type CreateType(AppDomain currentDomain)

      // Create an assembly.
      AssemblyName myAssemblyName = new AssemblyName();
      myAssemblyName.Name = "DynamicAssembly";
      AssemblyBuilder myAssembly =
      // Create a dynamic module in Dynamic Assembly.
      ModuleBuilder myModuleBuilder=myAssembly.DefineDynamicModule("MyModule");
      // Define a public class named "MyClass" in the assembly.
      TypeBuilder myTypeBuilder= myModuleBuilder.DefineType("MyClass",TypeAttributes.Public);

      // Define a private String field named "MyField" in the type.
      FieldBuilder myFieldBuilder= myTypeBuilder.DefineField("MyField",
      // Create the constructor.
      Type[] constructorArgs = { typeof(String) };
      ConstructorBuilder myConstructor = myTypeBuilder.DefineConstructor(
         MethodAttributes.Public, CallingConventions.Standard, constructorArgs);
      ILGenerator constructorIL = myConstructor.GetILGenerator();
      ConstructorInfo superConstructor = typeof(Object).GetConstructor(new Type[0]);
      constructorIL.Emit(OpCodes.Call, superConstructor);
      constructorIL.Emit(OpCodes.Stfld, myFieldBuilder);

      // Create the MyMethod method.
      MethodBuilder myMethodBuilder= myTypeBuilder.DefineMethod("MyMethod",
      ILGenerator methodIL = myMethodBuilder.GetILGenerator();
      methodIL.Emit(OpCodes.Ldfld, myFieldBuilder);
      if (myFieldBuilder.Attributes.Equals(FieldAttributes.Static))
            Console.WriteLine("Field attribute defined as Static");
      else if(myFieldBuilder.Attributes.Equals(FieldAttributes.Static|FieldAttributes.Private))
         Console.WriteLine("Field attributes are Static and Private");
      Console.WriteLine("ReflectedType of Field is: " + myFieldBuilder.ReflectedType);

      return myTypeBuilder.CreateType();

   [PermissionSetAttribute(SecurityAction.Demand, Name="FullTrust")]
   public static void Main()
      Type myType = CreateType(Thread.GetDomain());
      // Create an instance of the "HelloWorld" class.
      Object helloWorld = Activator.CreateInstance(myType, new Object[] { "HelloWorld" });
      // Invoke the "MyMethod"  of the "MyClass".
      Object myObject  = myType.InvokeMember("MyMethod",
         BindingFlags.InvokeMethod, null, helloWorld, null);
      Console.WriteLine("MyClass.MyMethod returned: \"" + myObject + "\"");
