还有个问题C# 中String 和string有什么区别？

Answer 1

string test = "54,143,55,142,56,142,57,142,58,142,59,142,60,142,61,142,62,142,63,142,64,142,65,142,66,142,67,142,68,142,69,142,70,142,71,142,72,142,73,142,74,142,75,142,76,142,77,142,78,142,79,142,80,142,81,142,82,142,83,142,84,142,85,142,86,142,87,143,87,144,87,145,87,146,87,147,87,148,87,149,87,150,87,151,87,152,86,153,85,153,84,153,83,153,82,153,81,153,80,153,79,153,78,153,77,153,76,153,75,153,74,153,73,153,72,153,71,153,70,153,69,153,68,153,67,153,66,153,65,153,64,153,63,153,62,153,61,153,60,153,59,153,58,153,57,153,56,153,55,153,54,152,54,151,54,150,54,149,54,148,54,147,54,146,54,145,54,144";
string[] nums = test.Split(',');
List<int> list = new List<int>();
foreach (string s in nums)
{
    list.Add(Convert.ToInt32(s));
}string是String的别名而已，没什么区别

Answer 2

String 是string的封装类，string 是他的属性而已，

Answer 3

string s=""
List<int> list = new List<int>();
foreach (string s in s.Split(','))
{
    list.Add(Convert.ToInt32(s));
}
String是.net Framework的类
string在C#中是System.String类的别名
对C#编译器来说string就是System.String

Answer 4

string str=""
List<int> list = new List<int>();
foreach (string s in str.Split(','))
{
  list.Add(Convert.ToInt32(s));
}

Answer 5

String 是封装类，string 是String 的属性。

Answer 6

string是String的别名
            string test = "54,143,55,142,56,142,57,142,58,142,59,142,60,142,61,142,62,142,63,142,64,142,65,142,66,142,67,142,68,142,69,142,70,142,71,142,72,142,73,142,74,142,75,142,76,142,77,142,78,142,79,142,80,142,81,142,82,142,83,142,84,142,85,142,86,142,87,143,87,144,87,145,87,146,87,147,87,148,87,149,87,150,87,151,87,152,86,153,85,153,84,153,83,153,82,153,81,153,80,153,79,153,78,153,77,153,76,153,75,153,74,153,73,153,72,153,71,153,70,153,69,153,68,153,67,153,66,153,65,153,64,153,63,153,62,153,61,153,60,153,59,153,58,153,57,153,56,153,55,153,54,152,54,151,54,150,54,149,54,148,54,147,54,146,54,145,54,144";
            Regex reg = new Regex(@"\d+");
            List<int> list = new List<int>();
            foreach (Match m in reg.Matches(test))
            {
                list.Add(Convert.ToInt32(m.Value));
            }            foreach (int i in list)
                Console.WriteLine(i);

Answer 7

List 使用完之后需要销毁吗？
链表和集合有什么区别？

Answer 8

ArrayList 和LISt有什么区别？

Answer 9

ArrayList属于System.Colletions命名空间，是一个基于object的数组类型，也就是说要将其运用于特定的类型需要拆箱操作。 
List<T>属于System.Collections.Generic(泛型)命名空间，可以指定数组基于的类。这一点比ArrayList好用的多

Answer 10

请问把一个 数加入list 是复制一份加入，还是把它的地址加进去？

Answer 11

ArrayList中元素是object， 如果是值类型，add,取时需要装箱，拆箱
List<T>是泛型，里面元素类型都为T

Answer 12

list是泛型 相当于多个实体的集合
arraylist是Object型的 操作时多数是要进行装箱拆箱的```

Answer 13

string s = "54,143,55,142,56,142,57,142,58,142,59,142,60,142,61,142,62,142,63,142,64,142,65,142,66,142,67,142,68,142,69,142,70,142,71,142,72,142,73,142,74,142,75,142,76,142,77,142,78,142,79,142,80,142,81,142,82,142,83,142,84,142,85,142,86,142,87,143,87,144,87,145,87,146,87,147,87,148,87,149,87,150,87,151,87,152,86,153,85,153,84,153,83,153,82,153,81,153,80,153,79,153,78,153,77,153,76,153,75,153,74,153,73,153,72,153,71,153,70,153,69,153,68,153,67,153,66,153,65,153,64,153,63,153,62,153,61,153,60,153,59,153,58,153,57,153,56,153,55,153,54,152,54,151,54,150,54,149,54,148,54,147,54,146,54,145,54,144";
        int[] result = s.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries).Select(t => int.Parse(t)).ToArray();

Answer 14

应该是把他的地址加进去，里面放的还是地址
上次我也遇到这样的问题，比如说判断两个list里的某个位置的值是否相等，这样写“list1[1]==list2[1]”即使这两个位置的值相当，但是编译时也认为不等，所以我觉得应该存储的是地址。

Answer 15

综合楼上各位的有关String和string的解释进行补充:
其实在定义string型变量时建议用String,而不是string.因为String编译器会编译的更快
