SqlConnectionStringBuilder.Clear Method

Clears the contents of the SqlConnectionStringBuilder instance.

Namespace:  System.Data.SqlClient
Assembly:  System.Data (in System.Data.dll)

'Declaration
Public Overrides Sub Clear

Implements

IDictionary.Clear

The Clear method removes all key/value pairs from the SqlConnectionStringBuilder, and resets all corresponding properties. This includes setting the Count property to 0, and setting the ConnectionString property to an empty string.

The following example demonstrates calling the Clear method. This example populates the SqlConnectionStringBuilder with some key/value pairs, and then calls the Clear method and shows the results.

Imports System.Data.SqlClient

Module Module1
    Sub Main()
        Dim builder As New SqlConnectionStringBuilder
        builder.DataSource = "(local)"
        builder.IntegratedSecurity = True
        builder.InitialCatalog = "AdventureWorks"
        Console.WriteLine("Initial connection string: " & builder.ConnectionString)

        builder.Clear()
        Console.WriteLine("After call to Clear, count = " & builder.Count)
        Console.WriteLine("Cleared connection string: " & builder.ConnectionString)
        Console.WriteLine()

        Console.WriteLine("Press Enter to continue.")
        Console.ReadLine()
    End Sub 
End Module
