catch区内的异常

是的,最后总是执行.

演示行为的简单示例:

private void Button_Click(object sender, EventArgs e)
{
    try
    {
        ThrowingMethod();
    }
    catch
    { 
    }
}

private void ThrowingMethod()
{
    try
    {
        throw new InvalidOperationException("some exception");
    }
    catch
    {
        throw;
    }
    finally
    {
        MessageBox.Show("finally");
    }
}
