由枚舉型

Question

填充組合框我有性別的枚舉：

enum gender 
{ 
    Female, 
    Male 
} 

現在，我想填充在鑄造字符串的枚舉的每一個字符串使用DisplayMember的值組合框（在此案「女」和「男」） ，然後ValueMember的枚舉的每一個索引（在這種情況下，0和1）

Answer 1

enum gender 
    { 
     Female, 
     Male 
    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
     foreach (var value in Enum.GetValues(typeof(gender))) 
     { 
      genderComboBox.Items.Add(value.ToString()); 
     } 
    } 

Answer 2

//Define the template for storing the items that should be added to your combobox 
    public class ComboboxItem 
    { 
     public string Text { get; set; } 

     public object Value { get; set; } 

     public override string ToString() 
     { 
      return Text; 
     } 
    } 

添加項目到您的ComboBox這樣的：

 //Get the items in the proper format 
     var items = Enum.GetValues(typeof(gender)).Cast<gender>().Select(i => new ComboboxItem() 
     { Text = Enum.GetName(typeof(gender), i), Value = (int)i}).ToArray<ComboboxItem>(); 
     //Add the items to your combobox (given that it's called comboBox1) 
     comboBox1.Items.AddRange(items); 

實施例用例：

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) 
    { 

     //Example usage: Assuming you have a multiline TextBox named textBox1 
     textBox1.Text += String.Format("selected text: {0}, value: {1} \n", ((ComboboxItem)comboBox1.SelectedItem).Text, ((ComboboxItem)comboBox1.SelectedItem).Value); 

    }
