C# 數組、集合和字符串之間的相互轉換

字符串轉為數組

string str = "1,2,3,4";

string[] strArr = str.Split(',');

 

數組轉為字符串

string[] scoresArr = { "1", "2", "3", "4", "5" };
string scores = string.Join(",", scoresArr);

 

字符串轉為集合

string str = "a,b,c";

List<string> strList = str.Split(',').ToList();

 

集合轉為字符串

List<string> abcList = new List<string> { "a", "b", "c", "d" };
string str = string.Join(",", abcList);
