Activator.Creat eInstance for new Array Element. Type Problem

[garak]

Hi,

I got the following problem :

I have an defined an Array of different Actions:
public PRootActions[] AllActions = new PRootActions [10];

I got a dynamic method where all Actions or other things like
Materials are loaded from a Database to my Actions or Materials
Array:
public void All_Db2Cl (Object[] AllData, ref int totalData)

This method is called like this:
PMain.myPArray. All_Db2Cl (AllAction, ref
PMain.myPGlobal s.totalActions) ;

Inside this Method I call the Activator.Creat eInstance Method to
initialize the Array Element:
AllData = Ativator.Create Instance (null,
"PentaEngine.PR ootActions");

With this instruction I receive the following error message :

An unhandled exception of type 'System.ArrayTy peMismatchExcep tion'
occurred in PentaEngine.exe

Additional information: Attempted to store an element of the incorrect
type into the array.
Does anyone has an idea ?

Thank you very much
Frank

Arrays must be created using System.Array.Cr eateInstance.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

OK Thanks,
but with Array.CreateIns tance I need to have a TYPE variable,
describing the desired type. I only have the typename as a STRING
variable.
Is there a way to get a TYPE variable with the typename ?

Type.GetType.
