int数组转换为string字符串

将数值数组拼合为字符串，一直使用循环的方式，代码虽简单，但总想更简洁，重构嘛

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，简洁的可爱！

 

int数组转有分隔符的字符串

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

int数组转string[]数组也不需要写循环

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() );

 

 

字符串数组排序

//arrID 是已有的字符串数组
IOrderedEnumerable<string> enumStr=  arrID.OrderBy(x => x);
 string[] newArrID = enumStr.ToArray<string>();
