为ComboBox指定显示整型标签

本文关键字：整型 标签 显示 ComboBox | 更新日期: 2023-09-27 17:53:29

嘿，我是soft的新手，但一直在使用它来帮助自己。无论如何，我一直在尝试让我的组合框中的项目在我的Race标签中显示一个int。Else可以工作，由于某种原因，当我单击列表中的第二个项目时，它将StrRaceLbl更改为1，但没有其他更改。不管怎么说，我没有办法了，我查了所有我能查到的东西，试图弄清楚这个问题。任何信息都有帮助!谢谢。

private void RaceCmbBx_SelectedIndexChanged_1(object sender, EventArgs e)
{
    int num1, num2, num0;
    int index = RaceCmbBx.SelectedIndex;
    num1 = 1;
    num2 = 2;
    num0 = 0;
    if (index == 1)
    {
        StrRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        DexRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        ConRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        WisRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        IntRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        ChaRaceLbl.Text = (Convert.ToInt32(num0)).ToString();
    }
    if (index == 2)
    {
        StrRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        DexRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        ConRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        WisRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        IntRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        ChaRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
    }
    else
        StrRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    DexRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    ConRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    WisRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    IntRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    ChaRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
}

这也是我用来添加项目到组合框:

// Content item for the combo box
private class Item
{
    public string Name;
    public int Value;
    public Item(string name, int value)
    {
        Name = name; Value = value;
    }
    public override string ToString()
    {
        // Generates the text shown in the combo box
        return Name;
    }
}
public Ch_Creation()
{
    InitializeComponent();
    // Put some stuff in the combo box
    RaceCmbBx.Items.Add(new Item("Dragonborn", 1));
    RaceCmbBx.Items.Add(new Item("Dwarf", 2));
    RaceCmbBx.Items.Add(new Item("  Hill Dwarf", 3));
}
private void RaceCmbBx_SelectedIndexChanged(object sender, EventArgs e)
{
    // Display the Value property
    Item itm = (Item)RaceCmbBx.SelectedItem;
    Console.WriteLine("{0}, {1}", itm.Name, itm.Value);
}

p。S是的，这是D&D

为ComboBox指定显示整型标签

看起来你漏掉了一对大括号和一个额外的if语句(如果我没记错的话)

private void RaceCmbBx_SelectedIndexChanged_1(object sender, EventArgs e)
{
    int num1, num2, num0;
    int index = RaceCmbBx.SelectedIndex;
    num1 = 1;
    num2 = 2;
    num0 = 0;

    if (index == 1)
    {
        StrRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        DexRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        ConRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        WisRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        IntRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        ChaRaceLbl.Text = (Convert.ToInt32(num0)).ToString();
    }
    else if (index == 2)
    {
        StrRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        DexRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        ConRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        WisRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        IntRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
        ChaRaceLbl.Text = (Convert.ToInt32(num1)).ToString();
    }
    else
    {
    StrRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    DexRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    ConRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    WisRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    IntRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
    ChaRaceLbl.Text = (Convert.ToInt32(num2)).ToString();
   }
}

好了，谢谢大家的帮助!我重新修改了代码，现在好像可以运行了。谢谢你的帮助。

       private void RaceCmbBx_SelectedIndexChanged_1(object sender, EventArgs e)
    {
        int num1, num2, num0;
        int index = RaceCmbBx.SelectedIndex;
        num1 = 1;
        num2 = 2;
        num0 = 0;
       if (index == 0)
        {
            StrRaceLbl.Text = num1.ToString();
            DexRaceLbl.Text = num1.ToString();
            ConRaceLbl.Text = num1.ToString();
            WisRaceLbl.Text = num1.ToString();
            IntRaceLbl.Text = num1.ToString();
            ChaRaceLbl.Text = num1.ToString();
        }
       else if (index == 1)
        {
            StrRaceLbl.Text = num2.ToString();
            DexRaceLbl.Text = num1.ToString();
            ConRaceLbl.Text = num2.ToString();
            WisRaceLbl.Text = num1.ToString();
            IntRaceLbl.Text = num1.ToString();
            ChaRaceLbl.Text = num2.ToString();
        }
        else
        {
            StrRaceLbl.Text = num2.ToString();
            DexRaceLbl.Text = num0.ToString();
            ConRaceLbl.Text = num1.ToString();
            WisRaceLbl.Text = num0.ToString();
            IntRaceLbl.Text = num1.ToString();
            ChaRaceLbl.Text = num0.ToString();
        }
    }
