New Post: How about generic method invocations?

vankirkc — Tue, 15 Jul 2008 08:05:43 GMT

I'd like to use your approach to handling generic class instantiation and generic method invocation, but I don't see any way to do it.

Here's a sample of code I'd like to use it for.

creating a strongly typed object:

CreateObject<T>( string a, int b, params object[] c )
{
SomeObject<T> rv = new SomeObject<T>( a, b, c )

return rv;
}

calling a strongly typed generic proc or function:

...
void Foo<T>( T arg1, T arg2 ) {}
Q bar<Q>( int i, double j ) { }

Is there a way to accomplish this with this thing?

Yes, i've a solution.

You can see a sample in my project Tangibilis in Codeplex.

Is there any expectation of extending this to support nested objects? aka something.somethingelse.something
I have taken your base and manipulated it with some other examples I have found to support this but it is not fully functional. As I do not fully understand how this works. I can supply you with the code I got if your willing to make the modification to your base to support this.

The problem I have with mine is as long as all of the nested objects are populate it works, but if they are not they will have a value of null and it causes an compare error. These objects are not of type nullable but they have a value of null.

Does this make any sense?
Thanks for the library its been very helpful.

NEW POST: How to access the field like System.Data.RelatedView.values ?

BixasBxB — Tue, 04 Dec 2007 11:18:20 GMT

The problem is that the type System.Data.RelatedView is internal into System.Data.dll so the following code can't be compiled :
Dynamic<System.Data.RelatedView>.Instance.Field<object[]>.Getter.CreateDelegate("values");

so I've wrote this to access it without your lib:

Type relatedViewType = System.Reflection.Assembly.GetAssembly(typeof(System.Data.DataSet))
.GetType("System.Data.RelatedView");

FieldInfo valuesField = relatedViewType.GetField("values", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);

//build setter
DynamicMethod setterDef = new DynamicMethod(relatedViewType.Name + "" + valuesField + "Setter",
typeof(void),
new Type[] { typeof(DataView), typeof(object[]) }, //define 1st param as DataView cause RelatedView is not an accessible type
relatedViewType);

ILGenerator setterIL = setterDef.GetILGenerator();
setterIL.Emit(OpCodes.Ldarg_0); //we expect in top of the stack object instance
setterIL.Emit(OpCodes.Ldarg_1);
setterIL.Emit(OpCodes.Stfld, valuesField);
setterIL.Emit(OpCodes.Ret); //note: we have to return, even if method is void

//assign s_RelatedViewKeyValuesSetter with the builded method
s_RelatedViewKeyValuesSetter = (Common.Utility.CodeEmit.Proc<DataView, object[]>)setterDef.CreateDelegate(typeof(Common.Utility.CodeEmit.Proc<DataView, object[]>));

COMMENTED FEATURE: Allow sorting on object graph public properties

ngruson — Thu, 29 Nov 2007 13:02:03 GMT

It would be helpful if there were a simple way to sort objects deeper in the object graph via their public properties.

An Example Scenario:
Parent object has children objects with property of Firstname
The ability to specify an orderby (or alternative means) to sort by Parent.Child.Firstname (where Firstname is a public property of Child object)
Comments: ** Comment from web user: ngruson **

I made some changes to the code to support this requirement and it works for me. You can get it at http://nils-gruson.blogspot.com/. Marc, can you take a look at this?

Greets,
Nils Gruson
