窗体上枚举控件 [英] Enumerating Controls on a Form

问题描述

我有一个就可以了约30控件的窗体，当用户点击一个按钮，从每个控制数据被保存到一个文件中。但是我需要去通过表单（这是我能做到）在每一个控制，但它需要是为了，例如，我需要开始就在表格的左上方和下工作，我的路到底正确的形式。

I have a form with about 30 controls on it, and when the user clicks a button, data from each control is saved to a file. But I need to go through every single control on the form (which I can do), but it needs to be in order, For example, I need to start right at the top left of the form and work my way down to the bottom right of the form.

这是一个foreach循环将如何运作？即：

Is this how a foreach loop would work? I.e.:

foreach(Control control in this.Controls)
{
}

或者它不经过他们为了？

Or does it not go through them in order?

推荐答案

这将返回控制在它们被添加到形式，而不是在可视顺序的顺序。

That would return the controls in the order they are added to the form, not in visual order.

如果您已经设置了的TabIndex 作为要分析你可以使​​用LINQ通过的TabIndex <对它们进行排序的控件相同的顺序/ code>。

If you have set up your TabIndex in the same order as you want to parse the controls you can use LINQ to sort them by TabIndex.

foreach (Control control in this.Controls.Cast<Control>().OrderBy(c => c.TabIndex))
{
}
