c# Rank屬性與GetUpperBound方法的深入分析

來源:互聯網
上載者:User

Array的Rank 屬性:
文法:public int Rank { get; } 得到Array的秩(維數)。
Array而GetUpperBound 方法:
文法:public int GetUpperBound(int dimension) 用於擷取 Array 的指定維度上限。

複製代碼 代碼如下:using System;
public class SamplesArray {
public static void Main() {
// Creates a new one-dimensional Array of type Int32.
Array my1DIntArray = Array.CreateInstance( typeof(Int32), 5 );
// Uses GetLowerBound and GetUpperBound in the for loop.
for ( int i = my1DIntArray.GetLowerBound(0); i <= my1DIntArray.GetUpperBound(0); i++ )
my1DIntArray.SetValue( i+1, i );
// Displays the bounds and values of the one-dimensional Array.
Console.WriteLine( "One-dimensional Array:" );
Console.WriteLine( "Rank/tLower/tUpper" );
Console.WriteLine( "{0}/t{1}/t{2}", 0, my1DIntArray.GetLowerBound(0), my1DIntArray.GetUpperBound(0) );
Console.WriteLine( "Values:" );
PrintValues( my1DIntArray );
Console.WriteLine();
// Creates a new three-dimensional Array of type Int32.
Array my3DIntArray = Array.CreateInstance( typeof(Int32), 2, 3, 4 );
// Uses GetLowerBound and GetUpperBound in the for loop.
for ( int i = my3DIntArray.GetLowerBound(0); i <= my3DIntArray.GetUpperBound(0); i++ )
for ( int j = my3DIntArray.GetLowerBound(1); j <= my3DIntArray.GetUpperBound(1); j++ )
for ( int k = my3DIntArray.GetLowerBound(2); k <= my3DIntArray.GetUpperBound(2); k++ ) {
my3DIntArray.SetValue( (i*100)+(j*10)+k, i, j, k );
}
// Displays the bounds and values of the multidimensional Array.
Console.WriteLine( "Multidimensional Array:" );
Console.WriteLine( "Rank/tLower/tUpper" );
for ( int i = 0; i < my3DIntArray.Rank; i++ )
Console.WriteLine( "{0}/t{1}/t{2}", i, my3DIntArray.GetLowerBound(i), my3DIntArray.GetUpperBound(i) );
Console.WriteLine( "Values:" );
PrintValues( my3DIntArray );
}
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();
}
}
/*
This code produces the following output.
One-dimensional Array:
Rank Lower Upper
0 0 4
Values:
1 2 3 4 5
Multidimensional Array:
Rank Lower Upper
0 0 1
1 0 2
2 0 3
Values:
0 1 2 3
10 11 12 13
20 21 22 23
