C# Array CreateInstance(Type, Int64[])

Description

Array CreateInstance(Type, Int64[]) creates a multidimensional Array of the specified Type and dimension lengths, with zero-based indexing. The dimension lengths are specified in an array of 64-bit integers.

Syntax

Array.CreateInstance(Type, Int64[]) has the following syntax.

public static Array CreateInstance(
  Type elementType,
  params long[] lengths
)

Parameters

Array.CreateInstance(Type, Int64[]) has the following parameters.

• elementType - The Type of the Array to create.
• lengths - An array of 64-bit integers that represent the size of each dimension of the Array to create. Each integer in the array must be between zero and Int32.MaxValue, inclusive.

Returns

Array.CreateInstance(Type, Int64[]) method returns A new multidimensional Array of the specified Type with the specified length for each dimension, using zero-based indexing.

Example

The following code example shows how to create and initialize a multidimensional Array.

/* w  ww  .  j  a  va2s .  co m*/
using System;
public class SamplesArray  {

   public static void Main()  {

      int[] myLengthsArray = new int[4] { 2, 3, 4, 5 };
      Array my4DArray=Array.CreateInstance( typeof(String), myLengthsArray );
      for ( int i = my4DArray.GetLowerBound(0); i <= my4DArray.GetUpperBound(0); i++ )
         for ( int j = my4DArray.GetLowerBound(1); j <= my4DArray.GetUpperBound(1); j++ )
            for ( int k = my4DArray.GetLowerBound(2); k <= my4DArray.GetUpperBound(2); k++ )
               for ( int l = my4DArray.GetLowerBound(3); l <= my4DArray.GetUpperBound(3); l++ )  {
                  int[] myIndicesArray = new int[4] { i, j, k, l };
                  my4DArray.SetValue( i, myIndicesArray );
               }

   }
}

The code above generates the following result.
