[英]Check if there are same elements in two string array?
I have two string arrays that hold values. 我有两个包含值的字符串数组。 How can i check if the first array contains an element that is also in the second array?
如何检查第一个数组是否包含同样位于第二个数组中的元素? I want to make a loop that checks through if there are any elements that are same in both, then i want to use that value and and display it in a message box.
我想创建一个循环来检查两者中是否有任何相同的元素,然后我想使用该值并将其显示在消息框中。 How do i compare them like that?
我如何比较那样?
string[] weekDays = { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" };
string[] potenDays = { "Mon", "Tue", "None", "None", "None", "None", "None" };
foreach (var weekDay in weekDays.Where(wd => potenDays.Contains(wd)))
{
// Show weekDay
}
