错误 CS0029：无法将类型“string”隐式转换为“int”

Question

In my program, I have to take 7 names and display them in alphabetical order. But I get the error

Error CS0029: Cannot implicitly convert type 'string' to 'int'

What am I doing wrong?

Code:

static void Main(string[] args)
{
    int size = 7;
    
    int[] people = new int[size];
    
    for(int i = 0; i < size; i++)
    {
        Console.WriteLine("Please enter " + i+1 + ". person's name: ");
    
        // Here
        people[i] = Console.ReadLine();
    }
    
    Console.WriteLine("After alphabetic ordering: ");
    
    Array.Sort(people);
    
    for (int j = 0; j < size; j++)
    {
        Console.WriteLine(j + 1 + "person's name : " + people[j]);
    }

    // ...
}

Answer 1

ReadLine method returns a string. So this code try to assign a string value to the int variable people. Rewrite the code like below.

String[] people = new String[size];

or

var people = new String[size];

Answer 2

You sould define string[] Not int[] so Use string[]

static void Main(string[] args)
{
    int size = 7;
    
    string[] people = new string[size];
    
    for(int i = 0; i < size; i++)
    {
        Console.WriteLine("Please enter " + i+1 + ". person's name: ");
        
        // Here
        people[i] = Console.ReadLine();
    }
    
    Console.WriteLine("After alphabetic ordering: ");
    
    
    
    Array.Sort(people);
    
    for (int j = 0; j < size; j++)
    {
        Console.WriteLine(j + 1 + "person's name : " + people[j]);
    }

    // ...
}
