SortedList.Synchronized(SortedList) Method is used to get the synchronized (thread-safe) wrapper for a SortedList object.
Syntax:
public static System.Collections.SortedList Synchronized (System.Collections.SortedList list);
Here, list is the name of the SortedList object which is to be synchronized.
Exception: This method will throw ArgumentNullException
if the list is null.
Below programs illustrate the use of above-discussed method:
Example 1:
// C# code to create a synchronized // (thread-safe) wrapper for a // SortedList object using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating an SortedList
SortedList mySortedList = new SortedList();
// Adding elements to SortedList
mySortedList.Add( "1" , "one" );
mySortedList.Add( "2" , "two" );
mySortedList.Add( "3" , "three" );
mySortedList.Add( "4" , "four" );
mySortedList.Add( "5" , "five" );
// Creating a synchronized wrapper
// around the SortedList.
SortedList mySortedList_1 =
SortedList.Synchronized(mySortedList);
// --------- Using IsSynchronized Property
// print the status of both SortedList
Console.WriteLine( "mySortedList SortedList is {0}." ,
mySortedList.IsSynchronized ? "synchronized" :
"not synchronized" );
Console.WriteLine( "mySortedList_1 SortedList is {0}." ,
mySortedList_1.IsSynchronized ? "synchronized" :
"not synchronized" );
}
} |
Output:
mySortedList SortedList is not synchronized. mySortedList_1 SortedList is synchronized.
Example 2:
// C# code to create a synchronized // (thread-safe) wrapper for a // SortedList object using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating an SortedList
SortedList mySortedList = new SortedList();
// Adding elements in SortedList
mylist.Add( "4" , "Even" );
mylist.Add( "9" , "Odd" );
mylist.Add( "5" , "Odd and Prime" );
mylist.Add( "2" , "Even and Prime" );
// it will give runtime error as
// table parameter can't be null
SortedList my2 = SortedList.Synchronized( null );
}
} |
Runtime Error:
Unhandled Exception:
System.ArgumentNullException: Value cannot be null.
Parameter name: list
Note: For the thread safety of a SortedList object, all operations must be done through this wrapper only.
