是否可以列出我们所有的字符串变量名称和值

Question

是否可以从实例和它的值列出我们的变量名称.

  public class Car
  {
    public string Color;
    public string Model;
    public string Made;
  }

  protected void Page_Load(object sender, EventArgs e)
  {

//Create new instance
    Car MyCar = new Car();
    MyCar.Color = "Red";
    MyCar.Model = "NISSAN";
    MyCar.Made = "Japan";

//SOMETHING HERE
    foreach (MyCar Variable in MyCar)
    {
      Response.Write("<br/>Variable Name"+  "XXX"+ "Variable Value");
    }

}

Answer 1

尝试这样的事情:

using System;

class Car
{
    public string Color;
    public string Model;
    public string Made;
}

class Example
{
    static void Main()
    {
        var car = new Car
        {
            Color = "Red",
            Model = "NISSAN",
            Made = "Japan"
        };

        foreach (var field in typeof(Car).GetFields())
        {
            Console.WriteLine("{0}: {1}", field.Name, field.GetValue(car));
        }
    }    
}

你需要反思来做到这一点.在这里,您可以看到一个类似的问题:如何获取类中所有公共变量的列表？(C#).

基于此,我认为您的案例将通过以下代码解决:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    FieldInfo[] myFieldInfo;
    Type myType = typeof(Car);

    myFieldInfo = myType.GetFields(BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Public);

    string result = @"The String fields of Car class are:";

    for (int i = 0; i < myFieldInfo.Length; i++)
    {
        if (myFieldInfo[i].FieldType == typeof(String))
        {
            result += "\r\n" + myFieldInfo[i].Name;
        }
    }

    MessageBox.Show(result);
}

public class Car
{
    public string Color;
    public string Model;
    public string Made;
}
