Examples

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.

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        SqlConnectionStringBuilder builder = 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();
    }
}

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

Remarks

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.
