示例1: Main
//引入命名空間
using System;
public class SamplesArray {
public static void Main() {
// Creates and initializes two new Arrays.
Array mySourceArray=Array.CreateInstance( typeof(String), 6 );
mySourceArray.SetValue( "three", 0 );
mySourceArray.SetValue( "napping", 1 );
mySourceArray.SetValue( "cats", 2 );
mySourceArray.SetValue( "in", 3 );
mySourceArray.SetValue( "the", 4 );
mySourceArray.SetValue( "barn", 5 );
Array myTargetArray=Array.CreateInstance( typeof(String), 15 );
myTargetArray.SetValue( "The", 0 );
myTargetArray.SetValue( "quick", 1 );
myTargetArray.SetValue( "brown", 2 );
myTargetArray.SetValue( "fox", 3 );
myTargetArray.SetValue( "jumps", 4 );
myTargetArray.SetValue( "over", 5 );
myTargetArray.SetValue( "the", 6 );
myTargetArray.SetValue( "lazy", 7 );
myTargetArray.SetValue( "dog", 8 );
// Displays the values of the Array.
Console.WriteLine( "The target Array contains the following (before and after copying):" );
PrintValues( myTargetArray, ' ' );
// Copies the source Array to the target Array, starting at index 6.
mySourceArray.CopyTo( myTargetArray, 6 );
// Displays the values of the Array.
PrintValues( myTargetArray, ' ' );
}
public static void PrintValues( Array myArr, char mySeparator ) {
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( "{0}{1}", mySeparator, myEnumerator.Current );
}
Console.WriteLine();
}
}輸出：
The target Array contains the following (before and after copying): The quick brown fox jumps over the lazy dog The quick brown fox jumps over three napping cats in the barn
示例2: Main
public class SamplesArray2{
public static void Main() {
// Creates and initializes the source Array.
Array myArrayZero=Array.CreateInstance( typeof(String), 3 );
myArrayZero.SetValue( "zero", 0 );
myArrayZero.SetValue( "one", 1 );
// Displays the source Array.
Console.WriteLine( "The array with lower bound=0 contains:" );
PrintIndexAndValues( myArrayZero );
// Creates and initializes the target Array.
int[] myArrLen = { 4 };
int[] myArrLow = { 2 };
Array myArrayTwo=Array.CreateInstance( typeof(String), myArrLen, myArrLow );
myArrayTwo.SetValue( "two", 2 );
myArrayTwo.SetValue( "three", 3 );
myArrayTwo.SetValue( "four", 4 );
myArrayTwo.SetValue( "five", 5 );
// Displays the target Array.
Console.WriteLine( "The array with lower bound=2 contains:" );
PrintIndexAndValues( myArrayTwo );
// Copies from the array with lower bound=0 to the array with lower bound=2.
myArrayZero.CopyTo( myArrayTwo, 3 );
// Displays the modified target Array.
Console.WriteLine( "\nAfter copying to the target array from index 3:" );
PrintIndexAndValues( myArrayTwo );
}
public static void PrintIndexAndValues( Array myArray ) {
for ( int i = myArray.GetLowerBound(0); i <= myArray.GetUpperBound(0); i++ )
Console.WriteLine( "\t[{0}]:\t{1}", i, myArray.GetValue( i ) );
}
}輸出：
The array with lower bound=0 contains:
[0]: zero
[1]: one
[2]:
The array with lower bound=2 contains:
[2]: two
[3]: three
[4]: four
[5]: five
After copying to the target array from index 3:
[2]: two
[3]: zero
[4]: one
[5]:
