求教，foreach如何赋值给数组

Question

我想用foreach遍历的第一个值赋值给string[0]，第二个值string[1]依此类推
但是for语句写不好，真心求教

Answer 1

count为你要遍历的对象的长度
for(int i=0;i<count;i++)
{
string[i]=value
}yourlist为你要遍历的对象
int i=0;
foreach(string str in yourlist)
{
string[i]=str;
i++;
}

Answer 2

 private void button1_Click(object sender, EventArgs e)
        {
            String[] s ={"1","2","3"};
            String[] co = new string[3];
            int n = 0;
            foreach(String str in s)
            {
              co[n]=str;
             n++;
            }            MessageBox.Show(co[0] + co[1] + co[2]);
        }

Answer 3

for可以这样写..string[] arr1=new string[3]{"1","2","3"};
string[] arr2=new string[3];
int cnt=arr1.length;
for(int i=0,i<cnt,i++)
{
arr2[i]=arr1[i];
}
foreach:string[] arrs=new string[3]{"1","2","3"};
List<string> arrList=new List<string>();
foreach(string arr in arrs)
{
arrList.add(arr);
}
string[] temp=arrList.ToArray();
