文本框到数组声明 [英] textbox to array declaration

问题描述

我对c＃编程很新，所以请耐心等待。我正在开发一个简单的小程序，它允许用户在同一个文本框中输入25个值，一旦完成，我希望能够在列表框中将这25个值显示为5个数组按5列排，我想找出数组中最大的数字。

Hi I’m fairly new to c# programming so please bear with me. I’m currently working on a "simple" little program which allows the user to enter 25 values into the same text box and once this has been done I want to be able to display this 25 values in a list box as an array of 5 row by 5 column and i want to find out the largest number in the array.

private void button1_Click(object sender, EventArgs e)
{
    int arrayrows = 5;
    int arraycolomns = 5;
    int[,] arraytimes;
    arraytimes = new int[array rows, array columns];


    // list_Matrix.Items.Add(tb_First.Text);
    for (int i = 0; i != 5; i++)
    {
        for (int j = 0; j != 5; j++)
        {
           array times [i,j]= Convert. To String(Tb_First.Text);
            list_Matrix.Items.Add(array times[i, j].To String());

        }

    }
}

我试图在列表中显示数组框。但它不起作用..因为我没有找到这个我不能移动到下一部分找到其中最大的数字。任何帮助将非常感激，因为我已经打砖墙



干杯

this is what i tried for displaying the array in a list box. but it isn't working.. since i dont find this i cant move to next section of finding the largest number among them. Any help will be much appreciated as i have hit a brick wall

Cheers

推荐答案

TextBox 内容（即其 Text 属性）是一个字符串，因此您应首先解析它以提取所有数字（使用 String.Split 方法和 Int32.TryParse 您可以轻松完成任务）。

The TextBox content (i.e. its Text property) is a string, hence you should first parse it in order to extract all the numbers (with String.Split method and Int32.TryParse you may easily accomlpish the task).
