如何：宣告及使用內部指標和 Managed 陣列 (C++/CLI)

  • 發行項

下列 C++/CLI 範例會示範如何宣告和使用內部指標陣列。

重要

這個語言功能支援 /clr 編譯器選項，但不是 /ZW 編譯器選項。

範例

程式碼

// interior_ptr_arrays.cpp
// compile with: /clr
#define SIZE 10

int main() {
   // declare the array
   array<int>^ arr = gcnew array<int>(SIZE);

   // initialize the array
   for (int i = 0 ; i < SIZE ; i++)
      arr[i] = i + 1;

   // create an interior pointer into the array
   interior_ptr<int> ipi = &arr[0];

   System::Console::WriteLine("1st element in arr holds: {0}", arr[0]);
   System::Console::WriteLine("ipi points to memory address whose value is: {0}", *ipi);

   ipi++;
   System::Console::WriteLine("after incrementing ipi, it points to memory address whose value is: {0}", *ipi);
}

Output

1st element in arr holds: 1
ipi points to memory address whose value is: 1
after incrementing ipi, it points to memory address whose value is: 2
