c＃winforms如何重复字符串数组成员？(c# winforms how to repeat string array members?)

首先，我需要从DataGridView.SelectedCells.Values创建一个字符串数组。 然后我需要将该字符串追加到自身，直到达到member.count的限制。 例如，如果

string [] = {"a", "b", "c"}; // Where abc are selectedCells.Values.

新的字符串[]应该是：

{"a", "b", "c", "a", "b", "c", "a", "b"}

例如，如果限制为8。

我怎么能解决这个问题呢？

First, I need to create a string array from a DataGridView.SelectedCells.Values. Then I need to append that string to itself, until a limit of member.count is reached. For example, if

string [] = {"a", "b", "c"}; // Where abc are selectedCells.Values.

the new string [] should be:

{"a", "b", "c", "a", "b", "c", "a", "b"}

if limit is 8, for example.

How could I solve this, please?

最满意答案

你可以在for循环中使用% （模数）。

string[] oldArr = new string[3] {"a","b","c"}; string[] newArr = new string[8]; int limit = 8; for ( int i = 0 ; i < limit ; i++ ) { newArr[i] = oldArr[i%oldArr.Length]; }

而已。

you can use the % (Modulus) in a for loop.

string[] oldArr = new string[3] {"a","b","c"}; string[] newArr = new string[8]; int limit = 8; for ( int i = 0 ; i < limit ; i++ ) { newArr[i] = oldArr[i%oldArr.Length]; }

That's it.
