Question

求，用C#如何把1-4,6变成1,2,3,4,6？还有1-3,5,7-10这样类似的字符串呢？

Answer 1

string s = "1-4,6";
string[] arr = s.split(',');
List<int> list = new List<int>();
foreach (string i in arr)
{
if (i.Contains("-"))
{
for (int x = Convert.ToInt32(i.split('-')[0]); x <= Convert.ToInt32(i.split('-')[1]); x++) list.Add(x);
}
else
list.Add(Convert.ToInt32(i));
}

手写的，你参考下
