我试图在我的Windows窗体应用程序中创建一个对象,但如果我在构造函数中创建它,那么我就无法在整个应用程序中访问它...(就像事件一样) Time1以下的代码不可用。我很高兴收到你的来信......
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace ClockApp
{
public partial class ClockApp : Form
{
public ClockApp()
{
InitializeComponent();
ClockApp Time1 = new ClockApp();
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void ClockApp_Load(object sender, EventArgs e)
{
}
private void btnOk_Click(object sender, EventArgs e)
{
//ClockApp Time1 = new ClockApp();
Time1.getHour = Convert.ToInt16(txtHour.Text);
Time1.getMin = Convert.ToInt16(txtMin.Text);
Time1.getSec = Convert.ToInt16(txtSec.Text);
if(rbUniversal.Checked == true)
{
Time1.ToUniversal();
}else if(rbStandard.Checked == true)
{
Time1.ToStandard();
}
else
{
lblTime.Text = "NOT Working...";
}
}
}
}
以下代码是我的班级:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace ClockApp
{
public partial class ClockApp : Form
{
// Fields
private int Hour;
private int Min;
private int Sec;
// Properties
public int getHour
{
get
{
return Hour;
}
set
{
if(value > 23 && value < 0)
{
Hour = 23;
}
else
{
Hour = value;
}
}
}
public int getMin
{
get
{
return Min;
}
set
{
if(value > 59 && value < 0)
{
Min = 59;
}
else
{
Min = value;
}
}
}
public int getSec
{
get
{
return Sec;
}
set
{
if(value > 59 && value < 0)
{
Sec = 59;
}
else
{
Sec = value;
}
}
}
// Constructors
// Methods
// ToUniversal()
public void ToUniversal()
{
lblTime.Text = Hour.ToString() + ":" + Min.ToString() + ":" + Sec.ToString();
}
// ToStandard()
public void ToStandard()
{
if(Hour > 12)
{
int[] Modifier = new int[12];
for (int i = 0; i < 12; i++)
{
Modifier[i] = i + 13;
if (Hour == Modifier[i])
{
Hour = i+1;
lblAMPM.Text = "PM";
}
}
lblTime.Text = Hour.ToString() + ":" + Min.ToString() + ":" + Sec.ToString();
}
else
{
lblAMPM.Text = "AM";
lblTime.Text = Hour.ToString() + ":" + Min.ToString() + ":" + Sec.ToString();
}
}
}
}
答案 0 :(得分:0)
this.props.children.map(function(child, i) {
...
}, this);

的新实例。
ClockApp
=&gt; Time1.getHour = Convert.ToInt16(txtHour.Text);
getHour = Convert.ToInt16(txtHour.Text);
=&gt; Time1.ToUniversal();
这应该使您的代码至少可以编译。
<强>错误:强>
ToUniversal();
总是假的。您必须使用value > 23 && value < 0
代替||
。&&
代码约定:
我知道你刚开始使用c#,但请检查通用编码约定以提高可读性:
value > 59 && value < 0
,Hour
或Min
即可。
