无法将类型为“ System.Reflection.RuntimePropertyInfo”的对象转换为类型为“ System.IConvertible”的对象

Question

I am having issues with the following code. I am iterating through a set to see if an object has a certain property type and if so, do some conversion to it.

var props = obj.GetType().GetProperties();
foreach (var p in props)
{     
    if (p.PropertyType == typeof(System.Boolean))
    {
    var conv = Convert.ToByte(p);
    }
}

I get the following error when I try to run it:

"Unable to cast object of type 'System.Reflection.RuntimePropertyInfo' to type 'System.IConvertible'."

Answer 1

I assume you want to get the value of the property and convert that to a byte, right? Not the property itself... so:

var conv = Convert.ToByte(p.GetValue(obj, null));

It seems odd to have it as a byte rather than a bool , admittedly... I'd have expected:

var conv = (bool) p.GetValue(obj, null);

I'd also personally use:

if (p.PropertyType == typeof(bool))

rather than spelling out the System.Boolean explicitly.
