Question

here a solution is given to get value of a property of a class by supplying its name . now I wonder how I can do the same in this condition :

I have a class MyClass . this class ha a property of type Foo named foo . the Foo has a property of type Bar named bar . and bar has a string property named value .

properties are not static .

I want to be able to get value of foo.bar.value by passing the string “foo.bar.value” as propertyName . in other word I want to pass the property path to get its value .

is it possible ?

Answer 1

You can do this with a recursive method. Each call takes the value with the first word in path and call the method again with the rest of the part.

public object GetPropertyValue(object o, string path)
{
    var propertyNames = path.Split('.');
    var value = o.GetType().GetProperty(propertyNames[0]).GetValue(o, null);

    if (propertyNames.Length == 1 || value == null)
        return value;
    else
    {
        return GetPropertyValue(value, path.Replace(propertyNames[0] + ".", ""));
    }
}
