为什么foreach不将字符串数组识别为数组

Question

我有这个代码:

private readonly string[,] sSOMETHING = new string[,]
{
    {"ONE", "TWO", "THREE"},
    {"FOUR", "FIVE", "SIX"}
};

...

foreach (string[] sELSE in sSOMETHING)
{
    ...
}

我在foreach中得到一个错误,即当sSOMETHING是一个数组时,它无法将字符串转换为字符串[].为什么它不将字符串数组识别为数组？foreach有多维数组的问题吗？

Answer 1

您正在创建2D数组,而不是数组的锯齿状数组.将声明更改为以下内容:

private readonly string[][] sSOMETHING = new string[][]
{
    new []{"ONE", "TWO", "THREE"},
    new []{"FOUR", "FIVE", "SIX"}
};
