示例1: Main
//引入命名空間
using System;
public class SamplesArray {
public static void Main() {
// Creates and initializes a new Array of type Int32.
Array myIntArray=Array.CreateInstance( typeof(System.Int32), 5 );
for ( int i = myIntArray.GetLowerBound(0); i <= myIntArray.GetUpperBound(0); i++ )
myIntArray.SetValue( i+1, i );
// Creates and initializes a new Array of type Object.
Array myObjArray = Array.CreateInstance( typeof(System.Object), 5 );
for ( int i = myObjArray.GetLowerBound(0); i <= myObjArray.GetUpperBound(0); i++ )
myObjArray.SetValue( i+26, i );
// Displays the initial values of both arrays.
Console.WriteLine( "Int32 array:" );
PrintValues( myIntArray );
Console.WriteLine( "Object array:" );
PrintValues( myObjArray );
// Copies the first element from the Int32 array to the Object array.
Array.Copy( myIntArray, myIntArray.GetLowerBound(0), myObjArray, myObjArray.GetLowerBound(0), 1 );
// Copies the last two elements from the Object array to the Int32 array.
Array.Copy( myObjArray, myObjArray.GetUpperBound(0) - 1, myIntArray, myIntArray.GetUpperBound(0) - 1, 2 );
// Displays the values of the modified arrays.
Console.WriteLine( "Int32 array - Last two elements should now be the same as Object array:" );
PrintValues( myIntArray );
Console.WriteLine( "Object array - First element should now be the same as Int32 array:" );
PrintValues( myObjArray );
}
public static void PrintValues( Array myArr ) {
System.Collections.IEnumerator myEnumerator = myArr.GetEnumerator();
int i = 0;
int cols = myArr.GetLength( myArr.Rank - 1 );
while ( myEnumerator.MoveNext() ) {
if ( i < cols ) {
i++;
} else {
Console.WriteLine();
i = 1;
}
Console.Write( "\t{0}", myEnumerator.Current );
}
Console.WriteLine();
}
}輸出：
Int32 array:
1 2 3 4 5
Object array:
26 27 28 29 30
Int32 array - Last two elements should now be the same as Object array:
1 2 3 29 30
Object array - First element should now be the same as Int32 array:
1 27 28 29 30
