从对象列表中获取变量

Question

How would you get a variable from each object in a list?

I've got this so far:

void SortList()
{
    int j = modules.Count;
    string[] titles = new string[j];

    for (int i = 0; i > modules.Count; i++)
    {
        titles[i] = 
    }
}

And I'm trying to get the variable "code" from each object in modules.

thanks.

Answer 1

Implying modules is a list or an array,

void SortList()
{
    int j = modules.Count;
    string[] titles = new string[j];

    foreach (String title in modules)
    {
        titles[i] = title.code
    }
}

As stated by Cuong Le, you could also use Linq to get a shorter version (Depending of which .Net version you are on).

titles = modules.Select(x => x.code).ToArray();

Answer 2

您可以使用带有Select方法的简单代码使用LINQ：

titles = modules.Select(x => x.code).ToArray();
