如何进行多个用户输入？ [英] How do I take multiple user inputs?

问题描述

如何使用数组（例如我在控制台中编写的代码）从1个texbox中获取多个用户输入。由于我是编程新手，我已经搜索了几个小时，我找不到任何东西。



我尝试过：



int i;

int size = 2;

string [] name = new string [size];

string [] age = new string [size];



Console.WriteLine（**输入姓名和年龄来查找记录* *）;



for（i = 0; i< size; i ++）

{

Console.WriteLine（输入名称：）;

name [i] = Console.ReadLine（）;



Console.WriteLine（ 输入年龄：）;

age [i] = Console.ReadLine（）;



}





Console.WriteLine（输入姓名或年龄来查找记录：）;

string find = Console.ReadLine（）;



for （i = 0;我<尺寸; i ++）

{



if（find == name [i]）

{

Console.WriteLine（姓名：+姓名[i] +年龄：+年龄[i]）;



i ++;

}



否则if（find == age [i]）

{





Console.WriteLine（年龄：+年龄[i] +姓名：+姓名[i]）;

i ++ ;



}

how do i take multiple user inputs from 1 texbox using array like the code i wrote in console. As i am new to programming, i have searched for hours and i can't find anything.

What I have tried:

int i;
int size = 2;
string[] name = new string [size];
string[] age = new string[size];

Console.WriteLine(" **Enter name and age to find your record** ");

for (i = 0; i < size; i++)
{
Console.WriteLine("Enter Name: ");
name[i] = Console.ReadLine();

Console.WriteLine("Enter Age: ");
age[i] = Console.ReadLine();

}


Console.WriteLine("Enter name or age to find record:");
string find = Console.ReadLine();

for (i = 0; i < size; i++)
{

if (find == name[i])
{
Console.WriteLine("Name : " + name[i] + " Age : " + age[i]);

i++;
}

else if (find == age[i])
{


Console.WriteLine("Age :" + age[i] + " Name : " + name[i]);
i++;

}
