두 가지 메서드의 IL을 병합하려고합니다. 하나는 기존 어셈블리 (MyAssembly.dll)의 메서드이고 다른 하나는 내 dnlib 코드와 동일한 프로젝트에 있습니다. 두 가지 방법을 모두 읽고 지침을 병합 한 다음 새 어셈블리에 쓰려고합니다. 이것은 내가 추가 그러나 때, 작동하는 경우, 새로운 방법 (나의 프로젝트의 하나) 새로운 어셈블리에 지시를 쓸 때 나는 예외를 얻을 문 (아마 다른 문) :두 메서드의 IL을 병합 할 때

그것은하지 않습니다 원래 코드 (MyAssembly.dll의 코드)에 if 문이 포함되어 있으면 예외가 throw됩니다.
하여 MyAssembly.dll의 코드 :
string str = GameManager.m_GameVersionString;
if (GameManager.m_Changelist != string.Empty)
{
str = str + " (" + GameManager.m_Changelist + ")";
}
return str + " Release ";
하여 MyAssembly.dll의 IL :

이 문제의 원인은 무엇인지 알 수 없습니다. 일리노이의 모든 레이블이 정확하다고 보입니다. if 문을 제거 할 때 dnlib는 일리노이를 어셈블리에 잘 작성합니다.
