Dim arr2() As Object
ReDim arr2(arr1.Length-1)
Array.Copy(arr1, arr2, arr1.Length)
Dim arr1() As Object = {"string1", "string2", "string3"}Dim arr2() As Object = arr1传值:
Dim arr1() As Object = {"string1", "string2", "string3"}Dim arr2() As ObjectReDim arr2(arr1.Length-1)Array.Copy(arr1, arr2, arr1.Length)
