隨手記，假設有以下類別

class Member
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Address { get; set; }
} 

 

初始化

private void Form1_Load(object sender, EventArgs e)
{
    this._memberList = new List<Member>() 
    { 
        new Member(){Name="Yao",Age=18,Address="火星"},
        new Member(){Name="GG",Age=20,Address="地球"}
    };
} 

轉成ToDictionary<string,Member>

 

Dictionary<string, Member> dictionary = this._memberList.ToDictionary(data => data.Name);
foreach (var item in dictionary)
{
    this.listBox1.Items.Add(item.Key);
}

 

 

轉成ToDictionary<string,string>

 

Dictionary<string, string> dictionary = this._memberList.ToDictionary(data => data.Name, data => data.Address);
foreach (var item in dictionary)
{
    this.listBox1.Items.Add(item.Key);
}
