ArrayList::Repeat Method
Returns an ArrayList whose elements are copies of the specified value.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System::Object
The Object to copy multiple times in the new ArrayList. The value can be nullptr.
- count
- Type: System::Int32
The number of times value should be copied.
Return Value
Type: System.Collections::ArrayListAn ArrayList with count number of elements, all of which are copies of value.
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | count is less than zero. |
ArrayList accepts nullptr as a valid value and allows duplicate elements.
This method is an O(n) operation, where n is count.
The following code example shows how to create and initialize a new ArrayList with the same value.
using namespace System; using namespace System::Collections; void PrintValues( IEnumerable^ myList ); int main() { // Creates a new ArrayList with five elements and initialize each element with a null value. ArrayList^ myAL = ArrayList::Repeat( 0, 5 ); // Displays the count, capacity and values of the ArrayList. Console::WriteLine( "ArrayList with five elements with a null value" ); Console::WriteLine( " Count : {0}", myAL->Count ); Console::WriteLine( " Capacity : {0}", myAL->Capacity ); Console::Write( " Values:" ); PrintValues( myAL ); // Creates a new ArrayList with seven elements and initialize each element with the string "abc". myAL = ArrayList::Repeat( "abc", 7 ); // Displays the count, capacity and values of the ArrayList. Console::WriteLine( "ArrayList with seven elements with a string value" ); Console::WriteLine( " Count : {0}", myAL->Count ); Console::WriteLine( " Capacity : {0}", myAL->Capacity ); Console::Write( " Values:" ); PrintValues( myAL ); } void PrintValues( IEnumerable^ myList ) { IEnumerator^ myEnum = myList->GetEnumerator(); while ( myEnum->MoveNext() ) { Object^ obj = safe_cast<Object^>(myEnum->Current); Console::Write( " {0}", obj ); } Console::WriteLine(); } /* This code produces the following output. ArrayList with five elements with a null value Count : 5 Capacity : 16 Values: ArrayList with seven elements with a string value Count : 7 Capacity : 16 Values: abc abc abc abc abc abc abc */
