Question

In C# how do you use reflection to get variables that doesn’t have getters/setters? For example the getValue method below will work for d2, but not d1.

public class Foo {

    public String d1;
    public String d2 { get; set; }

    public object getValue(String propertyName){
        return this.GetType().GetProperty(propertyName).GetValue(this, null);
    }
}

Answer 1

d1 is not a property. It is a field. Use the reflection methods for Fields instead.

public class Foo {

    public String d1;
    public String d2 { get; set; }

    public object getValue(String propertyName){
        var member = this.GetType().GetMember(propertyName).Single();
        if (member is PropertyInfo)
        {
            return ((PropertyInfo)member).GetValue(this, null);
        }
        else if (member is FieldInfo)
        {
            return ((FieldInfo)member).GetValue(this);
        }
        else throw new ArgumentOutOfRangeException();
    }
}
