Adds an OleDbParameter to the OleDbParameterCollection given the parameter name and value.

Public Function Add (parameterName As String, value As Object) As OleDbParameter

Parameters

parameterName
String

The name of the parameter.

value
Object

The Value of the OleDbParameter to add to the collection.

Returns

OleDbParameter

The index of the new OleDbParameter object.

Attributes
ObsoleteAttribute

Exceptions

InvalidCastException

The value parameter is not an OleDbParameter.

Remarks

Use caution when using this overload of the Add method to specify integer parameter values. Because this overload takes a value of type Object, you must convert the value to an Object type when the value is zero, as the following C# example demonstrates.

parameters.Add("@pname", Convert.ToInt32(0));

If you do not perform this conversion, the compiler will assume you are attempting to call the Add overload.
