RangeValidator公式正确可以提高50％ [英] RangeValidator Formula Correct to get 50% higher

问题描述

我有一个公式计算，应该找到一个值增加50％。如果值为100且50％增加将为151.我试图查看我的代码是否正确。我对此进行了测试，即使数量相同或小于50％，RangeValidator也会触发。如果代码是否正确，请告诉我。

I have a formula calculation that should find the 50% increase on a value. If a value is 100 and the 50% increase will be 151. I am trying to see if my code of getting this is correct. I tested this and the RangeValidator fires even when the number is the same or less than 50%. Please let me know if the code is correct or not.

int itxtVal13 = Convert.ToInt32(TextBox1.Text);
        int iminVal13 = (itxtVal13 * 0);
        int imaxVal13 = (itxtVal13 + itxtVal13 * 150 / 100);
        RangeValidatorLYFTE4050.MinimumValue = iminVal13.ToString();
        RangeValidatorLYFTE4050.MaximumValue = imaxVal13.ToString();

推荐答案

如果你有itxtVal13 = 100并在断点上放置一个断点line

If you have itxtVal13 = 100 and put a breakpoint on the line

RangeValidatorLYFTE4050.MinimumValue = iminVal13.ToString();

然后检查 imaxVal13 你看到了什么？



你计算了250％的itxtVal13而不是150％



将计算更改为

then examine the value of imaxVal13 what do you see?

You have calculated 250% of itxtVal13 not 150%

Either change the calculation to

int imaxVal13 = itxtVal13 + (itxtVal13 * 50 / 100);

或者

int imaxVal13 =(itxtVal13 * 150 / 100);

看到区别？





上面提到的断点就是imaxVal13的断点已经计算好了。您更正的代码（仅限此问题）如下所示：

See the difference?


The breakpoint on the line mentioned was just so that imaxVal13 had already been calculated. Your corrected code (this issue only) will look like:

int itxtVal13 = Convert.ToInt32(TextBox1.Text);
int iminVal13 = (itxtVal13 * 0);  // Which = 0 by the way!!
int imaxVal13 = itxtVal13 * (150 / 100);
RangeValidatorLYFTE4050.MinimumValue = iminVal13.ToString();
RangeValidatorLYFTE4050.MaximumValue = imaxVal13.ToString();
