Examples

The following example creates an OleDbConnectionStringBuilder instance, sets some of its properties, and then tries to determine whether various keys exist within the object by calling the ContainsKey method.

Remarks

Although setting the Provider property may implicitly fill in appropriate key/value pairs for the provider, the ContainsKey method does not return true for implicitly provided keys. This method returns true only for explicitly provided keys.
