Copying a single array to a multidimensional array

Question

I have declared the following two arrays. One is a single array of 4 elements, The other is a multidimensional array of 5 rows and 4 colums (see diagram below).

array<String^> ^single_row = {"E1", "E2", "E3", "E4"};
array<String^,2>^ multi_row=gcnew array<String^,2>(5,4);

Is there built in function I can use to copy the first array let's say the third row of the second array, without manually copying each element?
Note: I've tried array->copy but experienced error C3262: invalid array indexing: 1 dimension(s) specified for 2-dimensional 'cli::array ^'

I've attached a diagrams to assist for visualisation purposes. Array diagrams

maybe the way you use array->copy is incorrect. try something like Array::Copy(single_row,multi_row[3],4); specifying the row where to copy in multi_row — TravellingGeek

@stark This is not a duplicate. The link you have is of unmanaged c++ and the copy of a single arary. — Peter H

@GeraldSv I get the following errors when trying Array::Copy(single_row,multi_row[3],4); Error 1 error C3262: invalid array indexing: 1 dimension(s) specified for 2-dimensional 'cli::array<Type,dimension> ^' Error 2 error C2665: 'System::Array::Copy' : none of the 5 overloads could convert all the argument types — Peter H

I didn't find any function to do this. The only thing that I've found is that you can create the first array as multidimensional too.

array<String^,2> ^single_row = {{"E1", "E2", "E3", "E4"}};
array<String^,2>^ multi_row=gcnew array<String^,2>(5,4);

Then use:

Array::Copy(single_row,0,multi_row,2*4,4);

I hope this helps.

Kindest Regards
