我如何使用文本框将项目添加到字典中,因为我在类中创建了字典,所以我在将字典链接到列表框时也遇到了问题,我如何alphabet
从类调用到 Form1
我的课与字典
class MyCipher: ICipherDecipher
{
private Dictionary<string, string> alphabet;
public MyCipher()
{
alphabet = new Dictionary<string, string>();
alphabet.Add("4", " take 4");
alphabet.Add("3", " take 3");
alphabet.Add("5d", " for 5 days");
}
}
主要代码
public partial class Form1 : Form
{
private ICipherDecipher myCipher;
public Form1()
{
myCipher = new MyCipher();
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string textToBeCiphered = textBox1.Text;
string textCiphered = myCipher.Cipher(textToBeCiphered, 6);
textBox2.Text = textCiphered;
}
}
我如何将字典alphabet
从我的类调用到 Form1 中的主代码,以便我可以在列表框属性中显示它?
将类型更改myCipher
为MyCipher
改变这一行:
private ICipherDecipher myCipher;
到这一行:
private MyCipher myCipher;
为字母表添加属性
改变这一行:
private Dictionary<string, string> alphabet;
到这一行:
public Dictionary<string, string> alphabet {get; set;}
然后你可以将它绑定到你的列表框:
listBox1.DataSource = new BindingSource(myCipher.alphabet, null);
根据字典设置 ListView(2 列):
listView1.Items.Clear();
listView1.Items.AddRange(myCipher.alphabet.Select(c => new ListViewItem
(
new string[] { c.Key, c.Value}
)).ToArray());
根据字典设置 ListView(1 列):
listView1.Items.AddRange(myCipher.alphabet.Select(c => new ListViewItem(c.Key + " : " + c.Value)).ToArray());
