C＃将多维数组转换为单个数组并返回！ [英] C# Convert multidimensional array to single array and back !

问题描述

Hello Codeproject，



我如何转换

 [XmlIgnore] 
  public  Block [，] _Blocks { get ;  set ; } 

To：

  public 阻止[] _Blocks { get ;  set ; } 

回到：

  public 阻止[] _Blocks { get ;  set ;我需要保存块列表，但是XML序列化器不允许多维数组。
解决方案
 
如果您没有任何规范，这里有一些int []转换的示例代码。注意：这仅适用于具有相同宽度和高度的多维数组... 
 
 
 
 
  static   int  [，] SingleToMulti（ int  [] array） 
 {
  int  index =  0 ; 
  int  sqrt =（ int ）Math.Sqrt（array.Length）; 
  int  [，] multi =  new   int  [sqrt，sqrt]; 
  for （ int  y =  0 ; y <  sqrt; y ++）
 {
  for （< span class =code-keyword> int  x =  0 ; x <  sqrt ; x ++）
 {
 multi [x，y] = array [index]; 
 index ++; 
} 
} 
 返回多个; 
} 
 
 
 
 
 
 静态  int  [] MultiToSingle（ int  [，] array）
 {
 < span class =code-keyword> int  index =  0 ; 
  int  width = array.GetLength（ 0 ）; 
  int  height = array.GetLength（ 1 ）; 
  int  [] single =  new   int  [width * height]; 
  for （ int  y =  0 ; y <  height; y ++）
 {
  for （< span class =code-keyword> int  x =  0 ; x < 宽度; x ++）
 {
 single [index] = array [x，y]; 
 index ++; 
} 
} 
 返回单; 
} 
 
 
 
Hello Codeproject,



How would I converted



[XmlIgnore]
public Block[,] _Blocks { get; set; }




To:



public Block[] _Blocks { get; set; }




And back to:



public Block[] _Blocks { get; set; }
,



I need this for my XML Serializer, because I need to save the list of blocks, but the XML serializer does not allow Multi-dimensional array.
解决方案
Here''s some sample code of an int[] conversion if you don''t have any specifications. NOTE: this only works with multi-dimensional array''s with the same width and height...



static int[,] SingleToMulti(int[] array)
{
     int index = 0;
     int sqrt = (int)Math.Sqrt(array.Length);
     int[,] multi = new int[sqrt, sqrt];
     for (int y = 0; y < sqrt; y++)
     {
        for (int x = 0; x < sqrt; x++)
        {
            multi[x, y] = array[index];
            index++;
        }
      }
      return multi;
}




static int[] MultiToSingle(int[,] array)
{
     int index = 0;
     int width = array.GetLength(0);
     int height = array.GetLength(1);
     int[] single = new int[width * height];
     for (int y = 0; y < height; y++)
     {
         for (int x = 0; x < width; x++)
         {
            single[index] = array[x, y];
            index++;
         }
     }
     return single;
}
