*SOLVED* Oracle Data types and C#.NET

[DJ_Catboy]

Hi,

Does anybody know what the equivalent data type in C# is for an oracle NUMBER value? I have tried all that I can think and I keep getting an ORA-06650 error (wrong number or types of arguments in call to 'IFSAPP.SALES_PART_API.GET_LIST_PRICE').

odc = new OleDbCommand();
odc.CommandText = "ifsapp.sales_part_api.get_list_price('" + sContract + "','" + sPartNo + "' )";
odc.CommandType = CommandType.StoredProcedure;
odc.Connection = odbIFS;
				
prm = new OleDbParameter("rv",OleDbType.Integer,25);
prm.Direction = ParameterDirection.ReturnValue;
odc.Parameters.Add(prm);
				
prm = new OleDbParameter("contract_",OleDbType.VarChar,5);
prm.Direction = ParameterDirection.Input;
prm.Value = sContract;
odc.Parameters.Add(prm);
				
prm = new OleDbParameter("part_no_",OleDbType.VarChar,25);
prm.Direction = ParameterDirection.Input;
prm.Value = sPartNo;
odc.Parameters.Add(prm);
				
odc.ExecuteNonQuery();

Hope somebody can help!?
Thanks,
DJ
