遍历名称相似的控件 [英] Looping through controls with similar names

问题描述

我有一个带有选项卡式控件的窗体(5个选项卡)，在一个选项卡上，我有10个图片框，分别名为pic1，pic，pic3等.在VBA中，可以使用以下方式遍历控件:

I have a form with a tabbed control (5 tabs) and on one tab I have 10 picture boxes, named pic1, pic, pic3 and so on. In VBA it is possible to loop through the controls using something like this:

 For i = 1 To 10
    Me.Controls("Img" & i).Picture = Me.cboProperty.Column(i)
 Next

此刻我有

 this.pic1.DataBindings.Add("ImageLocation", this.mainTableBindingSource, "localPic1");
 this.pic2.DataBindings.Add("ImageLocation", this.mainTableBindingSource, "localPic2");
 this.pic3.DataBindings.Add("ImageLocation", this.mainTableBindingSource, "localPic3");

直到10，但是肯定有更好的方法吗?

until 10, but surely there is a better way?

推荐答案

就像那样，不.通常，您会加入如下一组控件:

Like that, no. Normally, you would acceess a group of controls like this:

foreach (var pictureBox in PictureTab.Controls.OfType(Of PictureBox)())
{
   pictureBox.Picture = //...
}

当然，这里的窍门是没有索引，无法知道要查看哪一列.但这很容易解决:

Of course, the trick here is that there is no index, to know which column to look at. But that's easy enough to get around:

int i = 0;
foreach (var pictureBox in PictureTab.Controls.OfType<PictureBox>())
{
   pictureBox.Picture = cboProperty.Column[i];
   i++;
}

根据您的修改，您可能需要这样做:

Based on your edit, you may want this:

int i = 0;
foreach(var pictureBox in PictureTab.Controls.OfType<PictureBox>())
{
    picutreBox.DataBindings.Add("ImageLocation", mainTableBindingSource, string.Format("loalPic{0}", i));
    i++;
}
