为什么当我的Window Forms应用程序出现循环时，我只能看到一些文本输出? [英] Why do I only see some of my text output when my Window Forms application has a loop?

问题描述

我试图提供两个数字(最大值和最小值)来创建乘法表.我当前的代码可以在控制台中完美运行，但是无法将其正确打印到Windows Forms Applications中的文本框中.我只能打印一个最大的数字.

Im trying to provide two numbers, a maximum and minimum, to create a multiplication table. My current code works perfectly in console, but I cant get it to properly print to a text box in Windows Forms Applications. I only manage to print a single, maximum, number.

private void MultiTab_CheckedChanged(object sender, EventArgs e)
{
    string final = "The Multiplication Table Is:";
    int i = Convert.ToInt32(Max.Text);
    int k = Convert.ToInt32(Min.Text);

    for (i = 1; i <= k; i++)
    {
        Result.Text = (i + "\t");
        for (int j = 1; j <= k; j++)
        {
            string x;

            if (i > k)  x = i * j + "\t";
            else x = j + "\t";
            Result.Text = final + x;
        }
        Result.Text = ("\n");
    }
}

推荐答案

Result.Text =将替换整个字符串，包括换行符.

Result.Text = will replace the entire string, including newlines.

您需要添加到Result.Text而不是替换它.

You need to add to Result.Text instead of replacing it.

在for循环之前，将其初始化为空字符串:

Before the for loop, initialize it to an empty string:

Result.Text = "";

然后在该点以下，始终添加而不是替换，例如

Then below that point, always append rather than replacing, e.g.

Result.Text += (i + "\t");

代替

Result.Text = (i + "\t");

以此类推.
