我是新来的,也是Visual Studio中C#编程的新手。c#visual studio如何将值从子类传递给父类?
目前我有一个关于C#重构的任务。
这是原班

以下归类是父类和子类,我想设置。
父:calculator.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace HUANG_Kai_30077528_Assign1
{
public partial class calculator : Form
{
//private string maleCaloriesCalculation();
//private string maleWeightCalculation();
//private string femaleCaloriesCalculation();
//private string femaleWeightCalculation();
public calculator()
{
InitializeComponent();
}
private void rbtnMale_CheckedChanged(object sender, EventArgs e)
{
}
private void btnCalculate_Click(object sender, EventArgs e)
{
//Clear old results
txtIdealWeight.Text = "";
txtCalories.Text = "";
/* Validate User Input: */
//Validate height (feet) is numeric value
double result;
if (!double.TryParse(txtFeet.Text, out result))
{
MessageBox.Show("Feet must be a numeric value.");
txtFeet.Select();
return;
}
//Validate height (inches) is numeric value
if (!double.TryParse(txtInches.Text, out result))
{
MessageBox.Show("Inches must be a numeric value.");
txtInches.Select();
return;
}
//Validate weight is numeric value
if (!double.TryParse(txtWeight.Text, out result))
{
MessageBox.Show("Weight must be a numeric value.");
txtWeight.Select();
return;
}
//Validate age is numeric value
if (!double.TryParse(txtAge.Text, out result))
{
MessageBox.Show("Age must be a numeric value.");
txtAge.Select();
return;
}
if (!(Convert.ToDouble(txtFeet.Text) >= 5))
{
MessageBox.Show("Height has to be equal to or greater than 5 feet!");
txtFeet.Select();
return;
}
/*End validation*/
calculation();
}
private void calculation()
{
if (rbtnMale.Checked)
{
txtCalories.Text = maleCalculator.maleCalories().ToString();
//txtCalories.Text = maleCalculator.maleCaloriesCalculation();
//txtIdealWeight.Text = maleCalculator.maleWeightCalculation();
}
else
{
txtCalories.Text = femaleCalculator.femaleCaloriesCalculation();
txtIdealWeight.Text = femaleCalculator.femaleWeightCalculation();
}
}
private void btnClear_Click(object sender, EventArgs e)
{
rbtnMale.Checked = false;
rbtnFemale.Checked = false;
txtFeet.Text = "";
txtInches.Text = "";
txtWeight.Text = "";
txtAge.Text = "";
txtCalories.Text = "";
txtIdealWeight.Text = "";
}
}
}
子类:maleCalculation.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace HUANG_Kai_30077528_Assign1
{
class maleCalculator: calculator
{
//private string maleCaloriesCalculation;
//private string maleWeightCalculation;
public maleCalculator maleCalories()
{
(66 + (6.3 * Convert.ToDouble(txtWeight.Text))
+ (12.9 * ((Convert.ToDouble(txtFeet.Text) * 12)
+ Convert.ToDouble(txtInches.Text)))
- (6.8 * Convert.ToDouble(txtAge.Text))).ToString();
return maleCalories();
//this.txtCalories.Text = new maleCalculator.maleCalories;
}
public maleCalculator maleWeight()
{
((50 + (2.3 * (((Convert.ToDouble(txtFeet.Text) - 5) * 12)
+ Convert.ToDouble(txtInches.Text)))) * 2.2046).ToString();
return maleWeight();
}
}
}
子类:femaleCalculation.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace HUANG_Kai_30077528_Assign1
{
class femaleCalculator : calculator
{
public double femaleCaloriesCalculation()
{
txtCalories.Text = (655 + (4.3 * Convert.ToDouble(txtWeight.Text))
+ (4.7 * ((Convert.ToDouble(txtFeet.Text) * 12)
+ Convert.ToDouble(txtInches.Text)))
- (4.7 * Convert.ToDouble(txtAge.Text))).ToString();
return femaleCaloriesCalculation();
}
public double femaleWeightCalculation()
{
txtIdealWeight.Text = ((45.5 + (2.3 * (((Convert.ToDouble(txtFeet.Text) - 5) * 12)
+ Convert.ToDouble(txtInches.Text)))) * 2.2046).ToString();
return femaleWeightCalculation();
}
}
}
正如我们可以看到,这两个亚类用于计算卡路里和理想体重。他们计划在原始类calculator.cs中取代private void calorieCalculation()和private void weightCalculation()。
我需要的功能是这样的:
当我执行程序和需要计算idealWeight和热量,父类calculator.cs将获得从公式计算出的结果包含在子类中,和文本框中的ToString。这就是为什么calculator.cs中有txtCalories和txtIdealWeight的原因。
所以问题是如何获得子类的结果,并填写文本框?
伙计们,请帮助我,因为这对我来说真的很重要!
谢谢大家!
谢谢你的帮助。但我尝试一次,失败。正如你所看到的,在父类calculator.cs中有另一个if和else的私有void计算()。而这个calculation()方法将被用来根据不同的性别自动填充特定的文本框。所以我需要的是我可以调用包含在子类中的计算公式的结果,当我运行该程序时,在calculator.cs的文本框中设置ToString。 – hkmax721 2013-05-04 10:54:08
我不理解你的评论,或者我不明白这个问题。你能更清楚一点吗? – WhyMe 2013-05-16 21:39:50
嗯,没关系。这项工作是在上周完成的。别管它吧。感谢您的帮助! – hkmax721 2013-05-17 07:20:56
