The ForEach-Object cmdlet performs an operation on each item in a collection of input objects. The input objects can be piped to the cmdlet or specified using the InputObject parameter. Starting in Windows PowerShell 3.0, there are two different ways to
An object that configures the behavior of this operation. localInit Func<TLocal> The function delegate that returns the initial state of the local data for each task. body Func<TSource,ParallelLoopState,TLocal,TLocal> The delegate that is invoked once per iteration. localFinally Action<TLoca...
Foreach From Variable enumerator to enumerate the enumerable object that a specified variable contains. The enumerable object can be an array, an ADO.NETDataTable, an Integration Services enumerator, and so on. For example, you can enumerate the values of an array that contains the name of ser...
看下jdk源码对Iterable接口的声明: /** Implementing this interface allows an object to be the target of * the "foreach" statement. * @since 1.5 */ public interface Iterable<T> { /** * Returns an iterator over a set of elements of type T. * * @return an Iterator. */ Iterator<T> ...
// Init an arraylist object int[] nArray = new int[100]; ArrayList arrInt = new ArrayList(); arrInt.AddRange( nArray ); // Use "foreach" to loop an arraylist foreach( int i in arrInt ) Debug.WriteLine( i.ToString() );
The ForEach-Object cmdlet performs an operation on each of a set of input objects. The input objects can be piped to the cmdlet or specified by using the InputObject parameter. The operation to perform is described within a script block that is provided to the cmdlet as the value of the...
