int数组转换为string字符串

int[] intArray = new int[] { 1, 2, 3, 4, 5 };
string result = string.Empty;
for (int i = 0; i < intArray.Length; i++)
{
    if (!string.IsNullOrEmpty(result))
       result += "," + intArray[i];
    else
       result = intArray[i].ToString();
}

int[] ints = { 1, 2, 3 };
string[] strs = Array.ConvertAll<int, string>(ints, delegate(int input) { return input.ToString();});
string result = string.Join(";", strs);

int[] ints={1,2,3,4};
List list = Arrays.asList(ints);
String[] arr = (String[])list.toArray(new String[ints.length]);

int[] ints = { 1, 2, 3 };
string[] output = Array.ConvertAll<int, string>( ints, i => i.ToString() );
