如何使用多个if语句并计算百分比？ [英] How to use multiple if statement and to calculate percentage?

问题描述

我有20个字段fname，lname，dob，email等

当用户填写两个字段时百分比增加

i已经使用

string value =（int）Math.Round（（double）（count * 100）/ MAX）+％;计算百分比



现在，当用户填写其他字段时，百分比必须增加



有人可以帮忙我...

提前致谢。



我尝试了什么：



int count = 0;

int max = 20;

if（fname！=&& lname！= ）

{

count + = 2;

string value =（int）Math.Round（（double）（count * 100） ）/ MAX）+％;

}

现在我想增加dob和更多字段

I have 20 fields fname,lname,dob,email etc
when user fill two fields the percentage increases
i have used
string value = (int)Math.Round((double)(count * 100) / MAX) + "%"; to calcuate the percent

Now, when user fills other fields the percentage must increase

Can someone help me...
Thanks in advance.

What I have tried:

int count=0;
int max=20;
if(fname !="" && lname!="")
{
count +=2;
string value = (int)Math.Round((double)(count * 100) / MAX) + "%";
}
now i want to increase for dob and further fields

推荐答案

试试这样



将所有控制值添加到列表中并迭代每个项目以检查空值

try like this

Add all the control values to a list and iterate each item for checking empty value

List<string> lstControls = new List<string>();
               lstControls.Add(TextBox1.Text.Trim());
               lstControls.Add(TextBox2.Text.Trim());
               lstControls.Add(TextBox3.Text.Trim());
               lstControls.Add(TextBox4.Text.Trim());
               lstControls.Add(TextBox5.Text.Trim());
               int max = lstControls.Count;
               int count = 0;
               for (int i = 0; i < max; i++)
                   if (lstControls[i] != "")
                       count++;


               string value = (int)Math.Round((double)(count * 100) / max) + "%";

if(fname !="" && lname!="")

您有20个要测试的字段，如果您开始组合测试字段，您将给了测试这20个领域的每一个组合。更好的选择是通过1测试字段。



我们不做你的HomeWork。

HomeWork不会测试你的技能乞求其他人做你的工作，它会让你思考并帮助你的老师检查你对所学课程的理解，以及你应用它们时遇到的问题。

你的任何失败都会帮助你的老师发现你的弱点并设定补救措施。

所以，试一试，重读你的课程并开始工作。如果您遇到特定问题，请显示您的代码并解释这个问题，我们可能会提供帮助。



作为程序员，您的工作是创建算法解决特定问题，你不能依赖别人永远为你做，所以有一段时间你必须学会​​如何。而且越快越好。

当你要求解决方案时，就像试图通过培训其他人来学习开车一样。

创建算法基本上是找到数学并做出必要的调整以适应你的实际问题。

You have 20 fields to test, if you start to test fields in combination, you will gave to test every single combination of those 20 fields. Better option is to test fields 1 by 1.

We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.

As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.
