와 싱글에서 인스턴스 메서드를 호출하는 방법 :.. :(작동 런타임을 불안정 수 있고, 내가 왜 잘 모릅니다 ... 나는 지역 추가나는 예외가되는 발광
도와주세요,하지만 여전히 작동하지하시기 바랍니다
메소드 (REF000001)를 동적으로 생성 할 :
public static int REF000001(int REF000002, object REF000003, DateTime REF000004)
{
return (int)typeof(REF000005).GetMethod("REF000006", new Type[] { typeof(int), typeof(object), typeof(DateTime) }).Invoke(REF000005.REF000008(), new object[] { REF000002, REF000003, REF000004 });
}
이 제가 단독에서 메소드를 호출 할 클래스이다
public class REF000005
{
private static REF000005 REF000007;
private REF000005()
{
}
public static REF000005 REF000008()
{
if (REF000007 == null)
REF000007 = new REF000005();
return REF000007;
}
public int REF000006(int REF000009, object REF000010, DateTime REF000011)
{
return 5;
}
}
