如何显示增加值而不是减少值

本文介绍了如何显示增加值而不是减少值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有这个代码可以让我增加两个数字。

I have this code that gives me the increase between two numbers.

int k = Convert.ToInt32(TextBoxLYTHCAS.Text.Replace(",", ""));
        int l = Convert.ToInt32(TextBoxTHCAS.Text.Replace(",", ""));
        TextBoxHC50.Text = Convert.ToString(Math.Round((Math.Abs(l - k)) * 100.0 / ((k))));
        TextBoxHC50.Text = Math.Round(Convert.ToDouble(TextBoxHC50.Text), 2).ToString();

它工作正常，直到我输入一些数字反过来。我将首先向您展示它的正确工作方式。

TextBoxLYTHCAS = 321

TextBoxTHCAS = 321

TextBoxHC50 = 93

正如您所看到的，这不是两个数字之间的增加。它等于相同的数字。如何才能获得在TextBoxHC50中显示的增加数字而不显示TextBoxHC50中的减少值？

It works fine until I entered in some numbers the other way around. I will show you first the correct way it works.

TextBoxLYTHCAS = 321
TextBoxTHCAS = 321
TextBoxHC50 = 93

As you can see this is not an increase between two numbers. It is equal to the same number. How can I just get the increase number to display in TextBoxHC50 and not show the decrease value in TextBoxHC50?

推荐答案

int k = Convert.ToInt32(TextBoxLYTHCAS.Text.Replace(",", ""));
           int l = Convert.ToInt32(TextBoxTHCAS.Text.Replace(",", ""));
           if (l >= k)
           {
               TextBoxHC50.Text = Convert.ToString(Math.Round((Math.Abs(l - k)) * 100.0 / ((k))));
               TextBoxHC50.Text = Math.Round(Convert.ToDouble(TextBoxHC50.Text), 2).ToString();
           }
           else
           {
               TextBoxHC50.Text = "";
           }
