나는 clay in VB.Net을 시도했지만 제대로 작동하지 못했습니다. 이 작품 ClayVB.Net을 사용할 때 Clay에서 익명 형식이 작동하지 않는 이유는 무엇입니까?
여기
는 C#
dynamic c = new ClayFactory();
var plant = c.Plant(new {LatinName = "test"});
Console.WriteLine(plant.LatinName);
Console.ReadLine();
하지만이
Dim c As Object = New ClayFactory
Dim plant = c.Plant(New With {.LatinName = "test"})
Console.WriteLine(plant.LatinName)
Console.ReadLine()
나는 VB.Net에서이 오류 메시지가 VB.Net에서 작동하지 않습니다
를> Cannot close over byref parameter
> '$arg1' referenced in lambda ''
나는 그것을 해결할 수 있다면 이것을 해결하는 방법을 100 % 확신하지 못합니다. 익명 형식의 VB.Net 구현은 약간 다릅니다.
나는이 줄에 오류가 발생합니다 : 누군가가 나에게 이것을 설명 할 수 있다면 감사하겠습니다
Dim plant = c.Plant(New With {.LatinName = "test"})
.
일리노이가 다른 것처럼 보입니다.
는 VB의 개인 필드 Latinname은 이것이다 :.field private initonly !'<LatinName>j__TPar' '<LatinName>i__Field'
.custom instance void [mscorlib]System.Diagnostics.DebuggerBrowsableAttribute::.ctor(valuetype [mscorlib]System.Diagnostics.DebuggerBrowsableState) = (01 00 00 00 00 00 00 00)
그리고 공공 방법 Get_LatinName은 이것이다 :
.field private initonly !T0 $LatinName
C 번호는입니다.
VB :
.method public specialname instance !T0 get_LatinName() cil managed
{
.custom instance void [mscorlib]System.Diagnostics.DebuggerNonUserCodeAttribute::.ctor() = (01 00 00 00)
// Code size 11 (0xb)
.maxstack 1
.locals init (!T0 V_0)
IL_0000: ldarg.0
IL_0001: ldfld !0 class VB$AnonymousType_0`1::$LatinName
IL_0006: stloc.0
IL_0007: br.s IL_0009
IL_0009: ldloc.0
IL_000a: ret
} // end of method VB$AnonymousType_0`1::get_LatinName
C 번호 :
.method public hidebysig specialname instance !'j__TPar'
get_LatinName() cil managed
{
// Code size 11 (0xb)
.maxstack 1
.locals init (!'j__TPar' V_0)
IL_0000: ldarg.0
IL_0001: ldfld !0 class 'f__AnonymousType0`1'j__TPar'>::'i__Field'
