ParameterCollection.Add Method (String, TypeCode, String)
Assembly: System.Web (in system.web.dll)
public int Add ( String name, TypeCode type, String value )
public function Add ( name : String, type : TypeCode, value : String ) : int
Parameters
- name
The name of the parameter.
- type
A string that serves as a default value for the parameter.
- value
A TypeCode that describes the type of the parameter.
Return Value
The index value of the added item.Use the Add(String,TypeCode,String) method to create and append a strongly typed Parameter object with a default value to the end of the collection. This implementation of the method creates the Parameter object using the name, type and value specified by the name, type and value parameters, respectively, and appends it to the collection.
The following code example demonstrates how the Add(String,TypeCode,String) method can be used to add new Parameter objects to a ParameterCollection collection by supplying the name, value, and type parameters. In this example, a Parameter object is added to an Update command of an Access data source control that provides the value of the current system time. The parameter is added with the TypeCode of DateTime.
