示例1: ROCollection
//引入命名空间
using System;
using System.Collections;
public class ROCollection : ReadOnlyCollectionBase {
public ROCollection( IList sourceList ) {
InnerList.AddRange( sourceList );
}
public Object this[ int index ] {
get {
return( InnerList[index] );
}
}
public int IndexOf( Object value ) {
return( InnerList.IndexOf( value ) );
}
public bool Contains( Object value ) {
return( InnerList.Contains( value ) );
}
}
public class SamplesCollectionBase {
public static void Main() {
// Create an ArrayList.
ArrayList myAL = new ArrayList();
myAL.Add( "red" );
myAL.Add( "blue" );
myAL.Add( "yellow" );
myAL.Add( "green" );
myAL.Add( "orange" );
myAL.Add( "purple" );
// Create a new ROCollection that contains the elements in myAL.
ROCollection myCol = new ROCollection( myAL );
// Display the contents of the collection using foreach. This is the preferred method.
Console.WriteLine( "Contents of the collection (using foreach):" );
PrintValues1( myCol );
// Display the contents of the collection using the enumerator.
Console.WriteLine( "Contents of the collection (using enumerator):" );
PrintValues2( myCol );
// Display the contents of the collection using the Count property and the Item property.
Console.WriteLine( "Contents of the collection (using Count and Item):" );
PrintIndexAndValues( myCol );
// Search the collection with Contains and IndexOf.
Console.WriteLine( "Contains yellow: {0}", myCol.Contains( "yellow" ) );
Console.WriteLine( "orange is at index {0}.", myCol.IndexOf( "orange" ) );
Console.WriteLine();
}
// Uses the Count property and the Item property.
public static void PrintIndexAndValues( ROCollection myCol ) {
for ( int i = 0; i < myCol.Count; i++ )
Console.WriteLine( " [{0}]: {1}", i, myCol[i] );
Console.WriteLine();
}
// Uses the foreach statement which hides the complexity of the enumerator.
// NOTE: The foreach statement is the preferred way of enumerating the contents of a collection.
public static void PrintValues1( ROCollection myCol ) {
foreach ( Object obj in myCol )
Console.WriteLine( " {0}", obj );
Console.WriteLine();
}
// Uses the enumerator.
// NOTE: The foreach statement is the preferred way of enumerating the contents of a collection.
public static void PrintValues2( ROCollection myCol ) {
System.Collections.IEnumerator myEnumerator = myCol.GetEnumerator();
while ( myEnumerator.MoveNext() )
Console.WriteLine( " {0}", myEnumerator.Current );
Console.WriteLine();
}
}输出：
Contents of the collection (using foreach): red blue yellow green orange purple Contents of the collection (using enumerator): red blue yellow green orange purple Contents of the collection (using Count and Item): [0]: red [1]: blue [2]: yellow [3]: green [4]: orange [5]: purple Contains yellow: True orange is at index 4.
