CLR Table valued functions error

Hi,

I'm trying to create a CLR functions

this is the Sql Function attribute and the FillRowMethod signature

[Microsoft.SqlServer.Server.SqlFunction(DataAccess = DataAccessKind.Read, SystemDataAccess = SystemDataAccessKind.Read,

FillRowMethodName = "FillRows",IsPrecise=true,

TableDefinition = "SOCIETA nvarchar(55),CLIENTE nvarchar(150),NUMEROCONTRATTO nvarchar(255),FIRMA datetime,CHIUSURA datetime,AUTORIZZATO float"

)]

publicstaticIEnumerable dbf_Create_RiepilogoAccordi(SqlInt32 commessa, SqlInt32 tipo_commessa, SqlInt32 progetto, SqlInt32 DAC, SqlInt32 figura, SqlDateTime dataFatturazioneDa, SqlDateTime dataFatturazioneA)

publicstaticvoid FillRows(Object obj, outSqlString SOCIETA, outSqlString CLIENTE, outSqlString NUMEROCONTRATTO, outSqlDateTime FIRMA, outSqlDateTime CHIUSURA, SqlDouble AUTORIZZATO)

Whe I try to deploy my function, I get the following error:

Error 1 Function signature of "FillRow" method (as designated by SqlFunctionAttribute.FillRowMethodName) does not match SQL declaration for table valued CLR function 'dbf_Create_RiepilogoAccordi' due to column 6. CM.Reports.SIA.RiepilogoAccordi

I get this error whichever combination of name/value I use for column 6

Can someone help me?

Thanks

Marco

I forgot to mark parameter AUTORIZZATO as an out parameter. the signature should be

publicstaticvoid FillRows(Object obj, outSqlString SOCIETA, outSqlString CLIENTE, outSqlString NUMEROCONTRATTO, outSqlDateTime FIRMA, outSqlDateTime CHIUSURA, out SqlDouble AUTORIZZATO)
