Examples

Im folgenden Beispiel wird ein OleDbConnection erstellt und einige seiner Eigenschaften in der Verbindungs Zeichenfolge festgelegt.The following example creates an OleDbConnection and sets some of its properties in the connection string.

// The connectionString argument contains the Connect Timeout
// keywords, as follows: "... ;Connect Timeout=30;"
public void InsertRow(string connectionString, string insertSQL)
{
    using (OleDbConnection connection = new OleDbConnection(connectionString))
    {
        // The insertSQL string contains a SQL statement that
        // inserts a new row in the source table.
        OleDbCommand command = new OleDbCommand(insertSQL);

        // Set the Connection to the new OleDbConnection.
        command.Connection = connection;

        // Open the connection and execute the insert command.
        try
        {
            connection.Open();
            command.ExecuteNonQuery();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        // The connection is automatically closed when the
        // code exits the using block.
    }
}
' The connectionString argument contains the Connect Timeout 
' keywords, as follows: "... ;Connect Timeout=30;"
Public Sub InsertRow(ByVal connectionString As String, _
    ByVal insertSQL As String)

    Using connection As New OleDbConnection(connectionString)
        ' The insertSQL string contains a SQL statement that
        ' inserts a new row in the source table.
        Dim command As New OleDbCommand(insertSQL)

        ' Set the Connection to the new OleDbConnection.
        command.Connection = connection

        ' Open the connection and execute the insert command.
        Try
            connection.Open()
            command.ExecuteNonQuery()
        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try
        ' The connection is automatically closed when the
        ' code exits the Using block.
    End Using
End Sub

Remarks

Der Wert 0 gibt keine Begrenzung an und sollte in einem ConnectionString vermieden werden, da der Verbindungsversuch unbegrenzt wartet.A value of 0 indicates no limit, and should be avoided in a ConnectionString because an attempt to connect will wait indefinitely.
