Question

我使用GUI创建了64个图片框。现在我想将这些图片框组合成一个图片盒阵列，因为我需要它不断更新所述图片框中的图片。

我有以下代码：

private PictureBox[] pictureBoxArray= new PictureBox[64]; //Initialize array to group picture boxes into picture box array

  private void Main_Load(object sender, EventArgs e)
    {
        ConvertGuiPBtoGuiPbArray(ref pictureBoxArray);
    }

public static void ConvertGuiPBtoGuiPbArray(ref PictureBox[] pictureBoxArray)
    {
        foreach(PictureBox index in pictureBoxArray)
        {
        //Some code to do the following:
        pictureBoxArray[0]=pictureBox1; //this is the name of the pictureBox on the GUI
        pictureBoxArray[1]=pictureBox2;
        pictureBoxArray[2]=pictureBox3;
        .
        .
        .
        pictureBoxArray[63]=pictureBox64;

       //

    }

我看过Controls.ofType的命令，但我似乎不理解它。任何建议将不胜感激。我在这里先向您的帮助表示感谢！

Answer 1

假设您坚持使用表单的设计和64个单独的pictureBoxNN属性，基本反射可以根据需要填充数组。我认为Controls不能保证订购正确。

for (int i = 0; i < 64; i++)
{
    pictureBoxArray[i] = (PictureBox)GetType().GetProperty("pictureBox" + (i + 1)).GetValue(this);
}

此代码将表单的所有图片框添加到pictureBoxArray

private PictureBox[] pictureBoxArray;
private void Main_Load(object sender, EventArgs e)
{
     pictureBoxArray = this.Controls.OfType<PictureBox>().OrderBy(x => x.Name).ToArray();
}

＆＃34;如果你想添加另一个容器的图片框，例如 groupbox 或任何容器是指Form >只需替换 ＆＃34;此＆＃34; ，您的容器名称。

如果您想按降序排序，可以使用 OrderByDescending 代替 OrderBy 。

完整的代码可以是这样的：

private static PictureBox[] pictureBoxArray; public static void ConvertGuiPBtoGuiPbArray(ContainerControl container) { pictureBoxArray = container.Controls.OfType<PictureBox>().OrderBy(x => x.Name).ToArray(); } private void Main_Load(object sender, EventArgs e) { ConvertGuiPBtoGuiPbArray(this);//Or Whatever container like groupbox }

如果它们没有嵌套在其他控件中，而是直接放在您的表单上，您可以这样做：

PictureBox[] pictureBoxes = this.Controls.OfType<PictureBox>().ToArray();

修改

对于嵌套控件，您需要传递所有控件容器并检查它们中是否包含PictureBox。你可以这样做：

private void Form_Shown(object sender, EventArgs e) { List<PictureBox> pictureBoxes = new List<PictureBox>(); GetAllPictureBoxes(ref pictureBoxes, this.Controls); PictureBox[] pictureBoxesArray = pictureBoxes.OrderBy(pb => pb.Name).ToArray(); } private void GetAllPictureBoxes(ref List<PictureBox> pictureBoxes, Control.ControlCollection controls) { foreach (Control control in controls) { if (control.HasChildren) GetAllPictureBoxes(ref pictureBoxes, control.Controls); if (control is PictureBox) pictureBoxes.Add((PictureBox)control); } }

好的，所以过了一段时间我开始使用以下方法：

private PictureBox[] pictureBoxArray = new PictureBox[64]; //Initialize array to group picture boxes into picture box array

private void Main_Load(object sender, EventArgs e)
    {
        ConvertGuiPBtoGuiPbArray(ref pictureBoxArray);
    }

public void ConvertGuiPBtoGuiPbArray(ref PictureBox[] pictureBoxArray)
{
        int i = 0;
        string NameofPictureBox;
        string PictureBoxNumber;

        foreach (var item in groupBox_DataLayer.Controls)
        {
            if (item is PictureBox)
            {
                NameofPictureBox = ((PictureBox)item).Name;
                PictureBoxNumber = Regex.Match(NameofPictureBox, @"\d+").Value; // \d+ is regex for integers only
                i = Int32.Parse(PictureBoxNumber);  //Convert only number string to int
                i = i - 1;  //bcs of index of array starts from 0-63, not 1-64
                pictureBoxArray[i] = (PictureBox)item; //put PictureBox object in desired position
            }

        }
}

这对我来说完全有效，我在排序方面遇到了问题，但现在一切正常。谢谢大家的帮助！

您可以使用LinQ查询来搜索具有特定名称的控件：

public void ConvertGuiPBtoGuiPbArray(ref PictureBox[] pictureBoxArray)
{
    for (int i = 0; i <= pictureBoxArray.Count() - 1; i++)
    {
        int count = i;
        pictureBoxArray[i] = (PictureBox)this.Controls.Cast<Control>().Where(c => c.Name.ToLower() == "picturebox" + (count + 1)).First();
    }
}

你基本上循环遍历从0到63的indizes并搜索名称的图片框＆＃34; picturebox +（index + 1）＆＃34;并将其分配给数组中的此索引。

如果源图片框未在this.Controls集合中排序，则会跳过问题。

鉴于您对组合框的评论：在这种情况下，图片框不属于this.Controls，您需要用

替换查询

pictureBoxArray[i] = (PictureBox)groupboxName.Controls.Cast<Control>().Where(c => c.Name.ToLower() == "picturebox" + (count + 1)).First();

将64个图片框组成图片框阵列
