通过“发射/反射”初始化类字段

class A
{
   B someField1;
   C someField2;
}

A someObject;

// 1 - using reflection
// these will actually be your dynamically created objects...
object a = CreateA();
object b = CreateB();
System.Reflection.FieldInfo someField1 = a.GetType().GetField(
    \"someField1\", 
    BindingFlags.Instance | BindingFlags.NonPublic);
someField1.SetValue(a, b);

// 2 - using dynamic (C# 4)
dynamic a = CreateA();
dynamic b = CreateB();
a.someField1 = b;

interface IObjectWithFields
{
    B someField;
    C someField;
}

object a = CreateA();
((IObjectWIthFields)a).someField1 = CreateB();
