如何在字符串数组中插入元素 [英] How do I insert elements in a string array

问题描述

我想在特定字符串之前在字符串数组中插入一个元素。



Ram

ravi

Teja

Vikram



在上面的字符串数组中，我想在Teja之前添加Kumar。



编译应该问我在哪里插入，并且字符串应该插入到所需的索引中。





这里我的代码：

I want to insert an element in string array before a particular string.

Ram
ravi
Teja
Vikram

Here in the above string array I want to add Kumar before Teja.

Compile should ask me where to insert and the string should be inserted in the required index.


Here my code:

Console.Write("Enter the size of the array: ");
          string inputSize = Console.ReadLine();
          int stringSize;
          int.TryParse(inputSize, out stringSize);

          string[] stringArray=new string[stringSize];
          for (int index = 0; index < stringSize; index++)
          {
              stringArray[index] = Console.ReadLine();
          }
          foreach (string strings in stringArray)
          {
              Console.WriteLine(strings);
          }

          Console.ReadLine();

推荐答案

您可能需要为此编写函数，例如

You may required to write function for this like

string[] RemoveAt(string[] array, int index){
    int newLength = array.Length - 1;

    if(newLength < 1)
    {
        return array;//probably want to do some better logic for removing the last element
    }

    //this would also be a good time to check for "index out of bounds" and throw an exception or handle some other way

    string[] result = new string[newLength];
    int newCounter = 0;
    for(int i = 0; i < array.Length; i++)
    {
        if(i == index)//it is assumed at this point i will match index once only
        {
            continue;
        }
        result[newCounter] = array[i];
        newCounter++;
    }

    result result;
}
