 "System.Data.OracleClient.OracleParameter does not contain a constructor that takes 8 arguments    C:\Documents and Settings\bers\Мои документы\Visual Studio 2010\Projects\Ora\Ora\OraTable.Designer.cs

There are several Constructors for OracleParameter:
 
* OracleParameter()
* OracleParameter(String, OracleType)
* OracleParameter(String, Object)
* OracleParameter(String, OracleType, Int32)
* OracleParameter(String, OracleType, Int32, String)
* OracleParameter(String, OracleType, Int32, ParameterDirection, String,   
  DataRowVersion, Boolean, Object)
* OracleParameter(String, OracleType, Int32, ParameterDirection, Boolean, Byte, 
  Byte, String, DataRowVersion, Object)
 
The compile error says that you try to instantiate the Class OracleParameter with 8 Parameters within OraTable.Designer.cs , but there seems to be no Constructor with 8 parameters. Looking at the listing above there is one constructor that could fit:
 
* OracleParameter(String, OracleType, Int32, ParameterDirection, String,
  DataRowVersion, Boolean, Object)
 
Initializes a new instance of the OracleParameter class that uses the parameter name, data type, size, direction, source column, source version, and other properties.
 
Maybe you are using unsupported datatypes?
 

Could you post the snippet where you try to instantiate OracleParameter? How does the instantiation look like? Which parameter you try to use?
