c#-获取选定微调器项的特定值或位置

我有个问题

我与一些客户创建了一个纺纱机。微调器是从一个包含4列的列表中构建的：Id、Name、Age、Gender。在微调器中，我创建了如下项目：
Id:1-姓名：John-年龄：46-性别：男性
Id:2-姓名：Micheal-年龄：32-性别：男性 等等

现在我想要的是获取所选项目的Id，但我无法确定它，因为我创建了一个自定义项目字符串。所以当我需要输入时，我当然会得到整个字符串。我如何才能只获取字符串的Id并切断：“Id:=>-姓名：…-年龄：…-性别：…”所以剩下的唯一一件事就是Id作为Int

private void CustomerSpinner_ItemSelected(object sender, AdapterView.ItemSelectedEventArgs e)
{
    Spinner spinner = (Spinner)sender;
    SelectedSpinnerCustomer = spinner.GetItemAtPosition(e.Position).ToString();
    LoadCustomerInfo(SelectedSpinnerCustomer);
}

因此，为了明确起见，我希望SelectedSpinnerCustomer是一个int。如何才能做到这一点？

最好的方法是创建一个自定义Spinner类，该类继承常规Spinner类并包含所有四个属性

public class MySpinner : Spinner
{
   public int Id { get; set; }
   public int Age { get; set; }
   public string Name { get; set; }
   public string Gender { get; set; }
} 

那么

private void CustomerSpinner_ItemSelected(object sender, AdapterView.ItemSelectedEventArgs e)
{
    MySpinner spinner = sender as MySpinner;
    int SelectedSpinnerCustomer = spinner.Id;
    int age = spinner.Age;
    string name = spinner.Name;
    string gender = spinner.Gender;
}

string

类中有几种不同的方法可用于此操作。这里有一个稍微简化的方法，它使用了多种字符串方法

//Save the string in a local variable with a short name for better readability
string str = spinner.GetItemAtPosition(e.Position).ToString();

//Split the string by the underscores ('-')
string[] splitted = str.Split("-");
//Now you have a string array with all the values by themselves
//We know that ID is the first element in the array since your string starts with the ID
//So save it in a new string
string idStr = splitted[0];
//idStr is now "id: x "
//Remove the spaces by replacing them with nothing
idStr = idStr.Replace(" ", "");
//idStr is now "id:x"
//To get only 'x' we need to remove "id:" which can be done in multiple ways
//In this example I will use String.Remove() method
//Start at index 0 and remove 3 characters. This will remove "id:" from "id:x"
idStr = idStr.Remove(0, 3);
//Now idStr is "x" which is an integer, so we can just parse it
int id = int.Parse(idStr);
//Now you have the id as an integer!

我需要在

私有无效客户pinner\u ItemSelected（对象发送者，AdapterView.ItemSelectedEventArgs e）

中执行什么操作？感谢您的帮助！谢谢你的帮助！
