OleDbParameter.DbType Property

Gets or sets the DbType of the parameter.

Namespace:  System.Data.OleDb
Assembly:  System.Data (in System.Data.dll)

public override DbType DbType { get; set; }

Property Value

Type: System.Data.DbType
One of the DbType values. The default is String.

Implements

IDataParameter.DbType

ExceptionCondition
ArgumentOutOfRangeException

The property was not set to a valid DbType.

The OleDbType and DbType are linked. Therefore, setting the DbType changes the OleDbType to a supporting OleDbType.

For a list of the supported data types, see the appropriate OleDbType member. For more information, see DataAdapter Parameters.

The following example creates an OleDbParameter and sets some of its properties.

public void CreateOleDbParameter() 
 {
    OleDbParameter parameter = new OleDbParameter("Description", OleDbType.VarChar, 88);
    parameter.Direction = ParameterDirection.Output;
 }
