When acquire the mining results, I got an error
"Try to read or write protection memory. this usually indicates other memory has been damaged"

The following is my code:

Microsoft.AnalysisServices.System.DataMining.AssociationRules asrule = new Microsoft.AnalysisServices.System.DataMining.AssociationRules();
DataTable dtResult = new DataTable(); 
asrule.GetHashCode(); // I think there is no problem in this line  
//The following occurs problem 
dtResult = asrule.GetItemsets("Table1", 0, 0, 1, 0, (double)0.01, "", true);

Here cue “Try to read or write protection memory. this usually indicates other memory has been damaged”


The results of debugging:

PFSetLastError(Int32 , PF_External , UInt16* , UInt16* , UInt64 )\r\n  
PFSetLastError(Int32 in_hrError, UInt16* in_szNote, UInt16* in_szTag, UInt64 in_mskState)\r\n

I load the function of Microsoft.AnalysisServices.System.DataMining.AssociationRules.
From the returned stack,the error occurs in
Microsoft.AnalysisServices.AdomdServer.g_GetMDContext()
that is this class: msmgdsrv.dll

Does anyone know the solution? Hope you could give me some help.Thanks.
