如何在C＃中的1维数组索引从1开始 [英] How to create a 1-Dimensional Array in C# with index starting at 1

问题描述

有关多维数组Array.CreateInstance可以用来创建非从零开始的索引数组，但是如果你尝试，对于一个一维数组（向量），如例如：

For multidimensional arrays Array.CreateInstance can be used to create non-zero index based arrays, but if you try that for a 1-dimensional arrays (vectors) as in e.g.:

public double[] myArray = (double[])Array.CreateInstance(typeof(double), new int[1] { 12 }, new int[1] { 1 });

这将在运行时从多维数组要转换成一维数组失败，失败

this will fail at run-time when the cast from the the multidimensional Array to a single-dimensional array fails

"Unable to cast object of type 'System.Double[*]' to type 'System.Double[]'"

现在我可以只创建一个零基于阵列并忽略第一个值，或偏移等工作，但我俯瞰一些C＃语法魔力，允许基于非零矢量？

Now I could just create a zero based array and ignore the first value, or work with offsets etc., but am I overlooking some c# syntactic magic that allows for non zero based vectors?

更新：

如果他说我要埃里克利珀的的话<一个href=\"http://stackoverflow.com/questions/955732/c-nonzero-based-arrays-are-not-cls-compliant\">There's没有明显的方式，使在C＃中一个非零基于阵列

I'll take Eric Lippert's word for it if he says "There's no obvious way to make a non-zero-based array in C#"

推荐答案

在C＃中所有的数组都是从零开始的。据我所知是没有办法创造一个1基于阵列。想象一下，什么样的乱七八糟的都不会发生，如果这是可能的。这里有一个类似的线程这就解释更多的细节问题 - C＃：非零基于阵列不符合CLS

All arrays in C# are zero based. As far as I know there is no way to create a 1 based array. Imagine what kind of a mess would have happened if that was possible. Here is a similar thread which explains the issue with more details - C#: Nonzero-based arrays are not CLS-compliant
