DbConnectionStringBuilder.Item Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets the value associated with the specified key.

Namespace: System.Data.Common
Assembly: System.Data (in system.data.dll)

public:
virtual property Object^ default [String^] {
	Object^ get (String^ keyword);
	void set (String^ keyword, Object^ value);

/** @property */
public Object get_Item (String keyword)

/** @property */
public void set_Item (String keyword, Object value)

JScript supports the use of indexed properties, but not the declaration of new ones.

Parameters

keyword

The key of the item to get or set.

Property Value

The value associated with the specified key. If the specified key is not found, trying to get it returns a null reference (Nothing in Visual Basic), and trying to set it creates a new element using the specified key. Passing a null (Nothing in Visual Basic) key throws an ArgumentNullException. Assigning a null value removes the key/value pair.

Exception typeCondition

ArgumentNullException

keyword is a null reference (Nothing in Visual Basic).

NotSupportedException

The property is set, and the DbConnectionStringBuilder is read-only.

-or-

The property is set, keyword does not exist in the collection, and the DbConnectionStringBuilder has a fixed size.

When you set this property, if the specified key already exists in the dictionary, the value is replaced; otherwise, a new element is created.

The following console application creates a new DbConnectionStringBuilder and adds key/value pairs to its connection string, using the Item property.
