if (field!=value)
{
field=value;
}
}

public class MyFieldInfoClass
{
public static void Main()
{
MyFieldClassB myFieldObjectB = new MyFieldClassB();
MyFieldClassA myFieldObjectA = new MyFieldClassA();
Type myTypeA = typeof(MyFieldClassA);
FieldInfo myFieldInfo = myTypeA.GetField("Field");
Type myTypeB = typeof(MyFieldClassB);
FieldInfo myFieldInfo1 = myTypeB.GetField("field",
BindingFlags.NonPublic | BindingFlags.Instance);
