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

public OleDbParameter(
	string name,
	OleDbType dataType,
	int size,
	string srcColumn
)

Parameters

One of the OleDbType values.
size
Type: System.Int32
The length of the parameter.

The value supplied in the dataType parameter is an invalid back-end data type.

The Size is inferred from the value of the dataType parameter if it is not explicitly set in the size parameter.

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