OleDbConnectionStringBuilder.ContainsKey(String) Method

Definition

Determines whether the OleDbConnectionStringBuilder contains a specific key.

public:
 override bool ContainsKey(System::String ^ keyword);
public override bool ContainsKey (string keyword);
override this.ContainsKey : string -> bool
Public Overrides Function ContainsKey (keyword As String) As Boolean

Parameters

keyword
String

The key to locate in the OleDbConnectionStringBuilder.

Returns

true if the OleDbConnectionStringBuilder contains an element that has the specified key; otherwise, false.

Exceptions

keyword is null (Nothing in Visual Basic).

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.
