Setting/getting the class properties by string name

You can add indexer property, a pseudocode:

public class MyClass 
{
     public object this[string propertyName] 
     {
        get
        {
           // probably faster without reflection:
           // like:  return Properties.Settings.Default.PropertyValues[propertyName] 
           // instead of the following
           Type myType = typeof(MyClass);                   
           PropertyInfo myPropInfo = myType.GetProperty(propertyName);
           return myPropInfo.GetValue(this, null);
        }
        set
        {
           Type myType = typeof(MyClass);                   
           PropertyInfo myPropInfo = myType.GetProperty(propertyName);
           myPropInfo.SetValue(this, value, null);
        }
     }
}

You can add an indexer to your class and use reflection to aces the properties:

using System.Reflection;

public class MyClass {

    public object this[string name]
    {
        get
        {
            var properties = typeof(MyClass)
                    .GetProperties(BindingFlags.Public | BindingFlags.Instance);

            foreach (var property in properties)
            {
                if (property.Name == name && property.CanRead)
                    return property.GetValue(this, null);
            }

            throw new ArgumentException("Can't find property");

        }
        set {
            return;
        }
    }
}
