注释
The IDataParameter interface enables you to implement a Parameter class, which represents a parameter to a Command object. An application does not create an instance of the IDataParameter interface directly, but creates an instance of a class that implements IDataParameter.
Classes that implement IDataParameter must implement the required members, and typically define additional members to add provider-specific functionality.
When you implement the IDataParameter interface, you should implement the following constructors:
Class |
Description |
|---|---|
PrvParameter() |
Initializes a new instance of the PrvDataParameter class. |
PrvParameter(string parameterName, object value) |
Initializes a new instance of the PrvDataParameter class with the parameter name and an object that is the value of the parameter. |
