使用C＃中的反射从字符串获取属性值-继承类的问题

Question

I have a class Cinherited which inherits from class Cbase .

When I attempt to list the properties for class Cinherited , using reflection, it only returns the properties for the base class, Cbase .

Here is the (somewhat simplified) code that demonstrates the problem:

public class Cinherited: Cbase
{
    public int x;

    public void printProperties()
    {
        Type t = this.GetType();
        PropertyInfo[] pi = t.GetProperties();
        foreach (PropertyInfo prop in pi)
        {
            // ERROR: Next line only prints properties in base class Cbase.
            Console.Write("Prop: {0}: {1}\n", prop.Name, prop.GetValue(this,null));             
        }
    }
}

Answer 1

It looks like you've declared fields rather than properties on your derived class. You can use code like this to access them:

public void PrintField()
{
    Type t = this.GetType();
    FieldInfo[] fi = t.GetFields();
    foreach (FieldInfo field in fi)
    {
        Console.Write("Field: {0}: {1}\n", field.Name, prop.GetValue(this));
    }
}

You can set the value of this field by calling SetValue() :

field.SetValue(this, -1);

Answer 2

Properties should be defined as

public int x {get; set;}

But this is a public field:

public int x;
