get all class attributes

[s.luongo]

Hello everybody,

Trying to get all attributes from a class (class1), I got them through
properties, is it a simple way to get all class atributes not using
their properties??

public void GetAllClassAttr ibutes()
{
Type classType = class1.GetType( );
PropertyInfo[] a_pi= classType.GetPr operties();
foreach ( PropertyInfo pi in a_pi)
{
if ( pi.CanRead ) pi.GetValue(res umen, null).ToString( );
}
Console.Read();
}

You need to make the distinction between attributes applied to the class
and those applied to the class members.

For a class, or more properly a type, you can use GetType().Attri butes.

For other members you would go via the TypeDescriptor to obtain the
MemberInfo objects for the members you were interested in such as
properties, fields and methods.

You are getting the property values, not attributes here. If you want
the attributes on the class, then you need to call the GetCustomAttrib utes
method on the Type instance for that method.

If you are asking how to get all the values on all the properties
exposed by a type, then what you are doing is the best way.

...
Type classType = class1.GetType( );

I really think that the right terminology would help here... first
"class1" appears to be an object, not a class - and you appear to be
obtaing the values of instance properties, nothing to do with
attributes. It also isn't clear whether "class1" and "resumen" are the
same thing, or what the code is intended to do (since it doesn't
output anything).

This is not intended as criticism; just so that you know the right
terms etc in case you want to clarify what you mean.

For other members you would go via the TypeDescriptor to obtain the

MemberInfo objects for the members you were interested in such as
properties, fields and methods.

Unless I missed it, TypeDescriptor doesn't really yield MemberInfo
instances - that is the reflection world. You can get at
PropertyDescrip tors and EventDescriptor s, but not fields (since
component-model [=TypeDescriptor] isn't implementation-specific, but
fields are /usually/ an implementation detail).

To get at MemberInfo (including FieldInfo) you would use the Type
directly.

You're right about the detail. Posting while tired ;-)
