Remarks

MakeArrayType 메서드는 런타임에 요소 형식이 계산 되는 배열 형식을 생성 하는 방법을 제공 합니다.The MakeArrayType method provides a way to generate array types whose element types are computed at run time.

참고 공용 언어 런타임에서는 벡터 (즉, 항상 0부터 시작 하는 1 차원 배열)와 다차원 배열을 구분 합니다.Note The common language runtime makes a distinction between vectors (that is, one-dimensional arrays that are always zero-based) and multidimensional arrays. 항상 하나의 차원에 있는 벡터에 차원이 하나만 발생 하는 다차원 배열로 같지는 않습니다.A vector, which always has only one dimension, is not the same as a multidimensional array that happens to have only one dimension. 벡터 형식을 만드는 경우에이 메서드 오버 로드를 데 수 이며 벡터 형식 만들기 위한 유일한 방법입니다.This method overload can only be used to create vector types, and it is the only way to create a vector type. MakeArrayType(Int32) 메서드 오버 로드를 사용 하 여 다차원 배열 형식을 만듭니다.Use the MakeArrayType(Int32) method overload to create multidimensional array types.
