ForEachItems.IsSynchronized Property
Returns a Boolean that indicates whether access to the ForEachItems collection is synchronized (thread-safe).
Namespace: Microsoft.SqlServer.Dts.Runtime.Enumerators.Item
Assembly: Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)
Syntax
'Declaration
Public ReadOnly Property IsSynchronized As Boolean
Get
'Usage
Dim instance As ForEachItems
Dim value As Boolean
value = instance.IsSynchronized
public bool IsSynchronized { get; }
public:
virtual property bool IsSynchronized {
bool get () sealed;
}
abstract IsSynchronized : bool
override IsSynchronized : bool
final function get IsSynchronized () : boolean
Property Value
Type: System.Boolean
true if access to the collection is synchronized (thread-safe); otherwise, false. The default is false.
Implements
Remarks
Implements ICollection.IsSynchronized. If a collection is thread safe, the IsSynchronized property returns true, and the programmer does not have to do anything to keep the collection thread safe.
If the property returns false, then the SyncRoot property returns an object that can be used with the C# lock keyword. For more information, see ICollection.IsSynchronized.
Examples
The ArrayList is a .NET Framework Class that inherits and implements the IsSynchronized property. The following code example shows how to synchronize an ArrayList, determine if an ArrayList is synchronized and use a synchronized ArrayList.
using System;
using System.Collections;
public class SamplesArrayList
{
public static void Main()
{
// Creates and initializes a new ArrayList.
ArrayList myAL = new ArrayList();
myAL.Add( "The" );
myAL.Add( "quick" );
myAL.Add( "brown" );
myAL.Add( "fox" );
// Creates a synchronized wrapper around the ArrayList.
ArrayList mySyncdAL = ArrayList.Synchronized( myAL );
// Displays the sychronization status of both ArrayLists.
Console.WriteLine( "myAL is {0}.", myAL.IsSynchronized ? "synchronized" : "not synchronized" );
Console.WriteLine( "mySyncdAL is {0}.", mySyncdAL.IsSynchronized ? "synchronized" : "not synchronized" );
}
}
Imports System
Imports System.Collections
Public Class SamplesArrayList
Public Shared Sub Main()
' Creates and initializes a new ArrayList.
Dim myAL As ArrayList = New ArrayList()
myAL.Add("The")
myAL.Add("quick")
myAL.Add("brown")
myAL.Add("fox")
' Creates a synchronized wrapper around the ArrayList.
Dim mySyncdAL As ArrayList = ArrayList.Synchronized(myAL)
' Displays the sychronization status of both ArrayLists.
Console.WriteLine("myAL is {0}.", myAL.IsSynchronized ? "synchronized" : "not synchronized")
Console.WriteLine("mySyncdAL is {0}.", mySyncdAL.IsSynchronized ? "synchronized" : "not synchronized")
End Sub
End Class
Sample Output:
myAL is not synchronized.
mySyncdAL is synchronized.
