ArrayList.SetRange Method
Assembly: mscorlib (in mscorlib.dll)
public void SetRange ( int index, ICollection c )
public function SetRange ( index : int, c : ICollection )
Not applicable.
Parameters
- index
The zero-based ArrayList index at which to start copying the elements of c.
- c
The ICollection whose elements to copy to the ArrayList. The collection itself cannot be a null reference (Nothing in Visual Basic), but it can contain elements that are a null reference (Nothing in Visual Basic).
| Exception type | Condition |
|---|---|
| index is less than zero. -or- index plus the number of elements in c is greater than Count. | |
| c is a null reference (Nothing in Visual Basic). | |
| The ArrayList is read-only. |
The following code example shows how to set and get a range of elements in the ArrayList.
using namespace System; using namespace System::Collections; void PrintValues( IEnumerable^ myList, char mySeparator ); int main() { // Creates and initializes a new ArrayList. ArrayList^ myAL = gcnew ArrayList; myAL->Add( "The" ); myAL->Add( "quick" ); myAL->Add( "brown" ); myAL->Add( "fox" ); myAL->Add( "jumped" ); myAL->Add( "over" ); myAL->Add( "the" ); myAL->Add( "lazy" ); myAL->Add( "dog" ); // Creates and initializes the source ICollection. Queue^ mySourceList = gcnew Queue; mySourceList->Enqueue( "big" ); mySourceList->Enqueue( "gray" ); mySourceList->Enqueue( "wolf" ); // Displays the values of five elements starting at index 0. ArrayList^ mySubAL = myAL->GetRange( 0, 5 ); Console::WriteLine( "Index 0 through 4 contains:" ); PrintValues( mySubAL, '\t' ); // Replaces the values of five elements starting at index 1 with the values in the ICollection. myAL->SetRange( 1, mySourceList ); // Displays the values of five elements starting at index 0. mySubAL = myAL->GetRange( 0, 5 ); Console::WriteLine( "Index 0 through 4 now contains:" ); PrintValues( mySubAL, '\t' ); } void PrintValues( IEnumerable^ myList, char mySeparator ) { IEnumerator^ myEnum = myList->GetEnumerator(); while ( myEnum->MoveNext() ) { Object^ obj = safe_cast<Object^>(myEnum->Current); Console::Write( "{0}{1}", mySeparator, obj ); } Console::WriteLine(); } /* This code produces the following output. Index 0 through 4 contains: The quick brown fox jumped Index 0 through 4 now contains: The big gray wolf jumped */
