int數組轉換為string字元串

将數值數組拼合為字元串，一直使用循環的方式，代碼雖簡單，但總想更簡潔，重構嘛

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();
}      

今天才知道真的有小技巧，簡潔的可愛！

int數組轉有分隔符的字元串

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

int數組轉string[]數組也不需要寫循環

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

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

字元串數組排序

//arrID 是已有的字元串數組
IOrderedEnumerable<string> enumStr=  arrID.OrderBy(x => x);
 string[] newArrID = enumStr.ToArray<string>();
