如何删除字符串数组的第一个元素 [英] How can I remove first element of string array

问题描述

我有一个字符串数组，其中最多有4个字符串

Hi,
I have a string array in which there are max of 4 strings

string[] userInput = new string[4];

我需要消除数组的第一个元素，并将剩余的元素分配给另一个字符串数组，如下所示

I need to eliminate first element of the array and assign the remaining elements to another string array like below

GWmsgDetails.GatewayBuses = userInput;

br mode =hold/>任何人都可以告诉我，我怎么能为此编写代码





谢谢

John

br mode="hold" />Can anyone please tell me, how can I wrote code for this


Thanks

推荐答案

尝试：

Try:

string[] userInput = new string[] { "hello", "there", "world"};
string[] withFirstBitMissing = new string[userInput.Length - 1];
Array.Copy(userInput, 1, withFirstBitMissing, 0, withFirstBitMissing.Length);  

使用linq的另一个解决方案：

another solution by using linq:

string[] arr1 = new string[4] { "1", "2", "3", "4" };
string[] arr2 = arr1.Skip(1).ToArray();

for循环解决方案



string [] userInput = new string [4] {1 ，2，3，4};

string [] userOutput = new string [userInput.Length -1];



for（int i = 1，j = 0; i< userInput.Length; i ++，j ++）

userOutput [j] = userInput [i];

Solution by for loop

string[] userInput = new string[4] {"1","2","3","4"};
string[] userOutput = new string[userInput.Length -1 ];

for (int i = 1, j = 0 ; i < userInput.Length; i++ , j++)
userOutput[j] = userInput[i];
