如何将2D清单二维数组在C＃

问题描述

我有下面的C＃列表：

 列表＆LT;应变及GT; listAllData =新的List＆LT;应变及GT;（）;listAllData.Add（新响应（）{
    strId =亲presponse.strId，
    则strName =亲presponse.strName
}）;
 

然后我将其转换为数组作为这样的：

 对象[]数组2 = listAllData.ToArray（）;
 

但是，当我试图用写数据到一个范围：

  rngValues​​.Value =数组2;
 

我得到一个错误

I am (reasonably) certain this is b/c the resulting array2 is not actually a 2D multidimensional array, but instead an array-of-arrays.

So my question is... How do I get my listAllData into a 2D array?

It is not a "jagged array" meaning there are always 2 elements in each entry.

解决方案

No, it's a 1-D array of Response objects. If you want it in a 2-D array of objects (where the row is the two string properties from the source object) you'll have to build a loop (Linq does not support 2-D arrays):

object[,] array2 = new object[listAllData.Count,2];
for(int i = 0; i < listAllData.Count; i++)
{
     array2[i,0] = listAllData[i].strId;
     array2[i,1] = listAllData[i].strName;
}
