获取所有客户端ID并将其存储在C＃中的列表中

Question

我正在编写应用程序，我希望获取所有客户端ID并将它们存储在列表中，以便在comboBox上将它们显示为DataSource。

像列表中的ClientId = 1,2,3一样。

            cln = new Client();

        List<String> getClients = new List<String>{ cln.Id };

        getClients.ElementAt(0);

        clientIdComboBox.DataSource = getClients;

编辑2：

List<Client> clients = new List<Client>();
        clients.Add(new Client() { Id = "1" });
        clients.Add(new Client() { Id = "2" });

        clientIdComboBox.DataSource = clients;

This is how it looks like when I added the above code. There are 2 but empty.

首先，您需要正确设置列表：

List<Client> clients = new List<Client();
clients.Add(new Client() { Id = 1});
clients.Add(new Client() { Id = 2});
[...]

clientIdComboBox.DataSource = clients;
