我有一个类型构建器,它生成两个相同的.ctor,一个没有方法体,另一个有所有init代码。
我从另一个类型和属性定义一个字段来访问该类型,因此需要在.ctor中初始化它
我应该从哪里开始寻找
代码如下
Public Sub ctor(ByVal type As TypeBuilder, ByVal FieldRefs As Dictionary(Of Type, FieldBuilder))
' Method attributes
Dim methodAttributes As System.Reflection.MethodAttributes = MethodAttributes.[Public]
Dim method As MethodBuilder = type.DefineMethod(".ctor", methodAttributes)
' Preparing Reflection instances
Dim ctor1 As ConstructorInfo = GetType(Object).GetConstructor(BindingFlags.Instance Or BindingFlags.[Public] Or BindingFlags.NonPublic, Nothing, Nothing, Nothing)
' Setting return type
method.SetReturnType(GetType(Void))
' Adding parameters
Dim gen As ILGenerator = method.GetILGenerator()
' Writing body
gen.Emit(OpCodes.Ldarg_0)
gen.Emit(OpCodes.[Call], ctor1)
'new up fields
For Each item In FieldRefs
AddCtor(type, gen, item.Value, item.Key)
Next
gen.Emit(OpCodes.Ret)
' finished
End Sub
Private Sub AddCtor(ByVal type As TypeBuilder, ByVal gen As ILGenerator, ByVal FieldBuilderRef As FieldBuilder, ByVal TypeToReference As Type)
Dim TypeCtor = TypeToReference.GetConstructor(BindingFlags.Instance Or BindingFlags.[Public] Or BindingFlags.NonPublic, Nothing, New Type() {}, Nothing)
gen.Emit(OpCodes.Ldarg_0)
gen.Emit(OpCodes.Newobj, TypeCtor)
gen.Emit(OpCodes.Stfld, FieldBuilderRef)
End Sub
代码接收类型字典,字段构建器在ctor中发出。新建早期在typebuilder主程序中构建的字段
答案 0 :(得分:1)
你确定一个不是.cctor
吗?但是你负责在TypeBuilder
中创建所有构造函数;除了DefineDefaultConstructor()
之外,你有没有打电话给DefineConstructor()
?这将创建一个空的默认构造函数...所以如果你不想要一个空构造函数,不要调用它。
