OracleParameter.Direction Property

Gets or sets a value that indicates whether the parameter is input-only, output-only, bidirectional, or a stored procedure return value parameter.

Namespace: System.Data.OracleClient
Assembly: System.Data.OracleClient (in system.data.oracleclient.dll)

public override ParameterDirection Direction { get; set; }
/** @property */
public ParameterDirection get_Direction ()

/** @property */
public void set_Direction (ParameterDirection value)

public override function get Direction () : ParameterDirection

public override function set Direction (value : ParameterDirection)

Not applicable.

Property Value

One of the ParameterDirection values. The default is Input.

Exception typeCondition

ArgumentException

The property was not set to one of the valid ParameterDirection values.

If the ParameterDirection is output, and execution of the associated OracleCommand does not return a value, the OracleParameter contains a null value.

Output, InputOut, and ReturnValue parameters returned by calling ExecuteReader cannot be accessed until you call Close on the OracleDataReader.

The following example creates a OracleParameter and sets some of its properties.

public void CreateOracleDbParameter() 
{
   OracleParameter parameter = new OracleParameter();
   parameter.ParameterName = "pDName";
   parameter.DbType = DbType.String;
   parameter.Value = "ENGINEERING";
   parameter.SourceColumn = "DName";
}
