多维与锯齿状数组 [英] Multidimensional vs Jagged array

问题描述

我使用了如下的多维数组

I have used a MultiDimesional Array as follows

  string[,] Columns = { { "clientA", "clientB" }}

    if (Columns.Length != 0)
            {
                for (int i = 0; i < Columns.Length / 2; i++)
                {
                    bulkCopy.ColumnMappings.Add(Columns[i, 0], Columns[i, 1]);
                }
            }

代码分析后，我收到警告消息，

After code analysis I got warning message as

Severity    Code    Description Project File    Line    Suppression State
Warning CA1814  'Order.GetLastOrderID()' uses a multidimensional array of  
'string[,]'. Replace it with a jagged array if possible.    

我已经在互联网上研究了锯齿状阵列，但是如何用锯齿状阵列替换我的阵列.

I have researched jagged arrays on internet but How do I replace my array with jagged array.

推荐答案

锯齿状的数组是数组的数组，因此您将定义更改为:

A jagged array is an array of arrays, so you change your definition to:

string[][] Columns = { new string[] { "clientA", "clientB" }};

从...更改阵列访问权限

Change array access from...

var value = Columns[0,0];

...到...

var value = Columns[0][0];

您还可以选择禁止显示警告(右键单击警告，然后选择所需的选项). 根据MSDN ，此警告可以安全地在某些情况下.在更改代码之前，请检查您的情况是否如此.

You also have the option to suppress the warning (right-click on it and select the option you need). According to MSDN, this is a warning that is safe to suppress in certain cases. Check if yours is such a case before you change the code.
