Update a property on an object knowing only its name

Question

I have some public variables that are defined as follows:

public class FieldsToMonitor
{
    public int Id { get; set; }
    public string Title { get; set;          


        

Answer 1

This is all heavily dependent on how these values are being retrieved, and it is difficult to tell from your limited example if the values are strings or the correct type just boxed as an object.

That being said, the following could work (but is hardly efficient):

public static void SetValue(T obj, string propertyName, object value)
{
    // these should be cached if possible
    Type type = typeof(T);
    PropertyInfo pi = type.GetProperty(propertyName);

    pi.SetValue(obj, Convert.ChangeType(value, pi.PropertyType), null);
}

Used like:

SetValue(fm, field.Name, revision.Fields[field.Name].Value);
// or SetValue(fm, ...);
