.Net Framework 변수 대입 부분 HEX 코드

요즘 많은 프로그램을 .Net을 사용해서 만듭니다.
.Net 같은 경우 어셈블러 코드가 좀 달라서 참고용으로 간단히 설명해 보려고 합니다.
아래와 같이 VB.Net 을 이용해서 프로그램을 짰습니다.

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim bool As Boolean
        Dim num As Integer
        Dim str As String

        bool = rRutnreTrue()
        bool = rRutnreFalse()
        bool = True
        bool = False

        num = 1
        num = 2
        num = rReturnNum1()
        num = rReturnNum1()

        str = "Test"
        str = rReturnString()

    End Sub

    Function rRutnreTrue() As Boolean
        Return True
    End Function

    Function rRutnreFalse() As Boolean
        Return False
    End Function

    Function rReturnNum1() As Integer
        Return 1
    End Function

    Function rReturnNum2() As Integer
        Return 2
    End Function

    Function rReturnString() As String
        Return "TEST"
    End Function

이 경우 어셈블러 코드는 다음과 같습니다.

  .method private instance void Form1_Load(object sender, class [mscorlib]System.EventArgs e)
                                        // DATA XREF: WindowsApplication1.Form1__.ctor+A r
  {
    .maxstack 1
    .locals init (bool V0,
                  int32 V1,
                  string V2)

    stloc.1
    ldstr    aTest                      // "Test"
    stloc.2
    ldarg.0
    callvirt instance string WindowsApplication1.Form1::rReturnString()
    stloc.2
    nop
    ret
  }

  .method public instance bool rRutnreTrue()
                                        // CODE XREF: WindowsApplication1.Form1__Form1_Load+2 p

    ret
  }

    ldc.i4.0
    stloc.0
    br.s     loc_D45

loc_D45:                                // CODE XREF: WindowsApplication1.Form1__rRutnreFalse+3 j
    ldloc.0
    ret
  }

  .method public instance int32 rReturnNum1()
                                        // CODE XREF: WindowsApplication1.Form1__Form1_Load+18 p
                                        // WindowsApplication1.Form1__Form1_Load+1F p
  {
    .maxstack 1
    .locals init (int32 V0)
    nop
    ldc.i4.1
    stloc.0
    br.s     loc_D55

loc_D55:                                // CODE XREF: WindowsApplication1.Form1__rReturnNum1+3 j
    ldloc.0
    ret
  }

  .method public instance int32 rReturnNum2()
  {
    .maxstack 1
    .locals init (int32 V0)
    nop
    ldc.i4.2
    stloc.0
    br.s     loc_D65

loc_D65:                                // CODE XREF: WindowsApplication1.Form1__rReturnNum2+3 j
    ldloc.0
    ret
  }

  .method public instance string rReturnString()
                                        // CODE XREF: WindowsApplication1.Form1__Form1_Load+2C p
  {
    .maxstack 1
    .locals init (string V0)
    nop
    ldstr    aTest_0                    // "TEST"
    stloc.0
    br.s     loc_D79

loc_D79:                                // CODE XREF: WindowsApplication1.Form1__rReturnString+7 j
    ldloc.0
    ret
  }

보통 특정 연산을 하고 True 나 False 를 반환 하는 함수를 만들어 쓴다고 할때...
연산과정 다 무시하고...무조건 TRUE를 반환 하게 한다면...
코드 시작 부분에서 바로 Return True 를 하면 되겠죠...

HEX 코드로 보면 다음과 같습니다.

ldc.i4.1 에 해당하는 HEX 코드는 0x17 입니다.
