範例

下列程式碼範例示範如何使用 SupportsSearching 成員。 如需完整的範例，請參閱類別概觀主題。

private void button1_Click(object sender, EventArgs e)
{
    if (binding1.SupportsSearching != true)
    {
        MessageBox.Show("Cannot search the list.");
    }
    else
    {
        int foundIndex = binding1.Find("Name", textBox1.Text);
        if (foundIndex > -1)
            listBox1.SelectedIndex = foundIndex;
        else
            MessageBox.Show("Font was not found.");
    }
}

    Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) _
        Handles button1.Click

        If binding1.SupportsSearching <> True Then
            MessageBox.Show("Cannot search the list.")
        Else
            Dim foundIndex As Integer = binding1.Find("Name", textBox1.Text)
            If foundIndex > -1 Then
                listBox1.SelectedIndex = foundIndex
            Else
                MessageBox.Show("Font was not found.")
            End If
        End If

    End Sub
End Class

備註

如果資料來源不是 IBindingList ， SupportsSearching 則一律會傳 false 回 。
