C# 如何在表单中动态放置项？

c语言中是否有类似于css的“float:left | right | none | inherit”？
我想在我的表单中显示-

TextBox

和每个

TextBox

-

PictureBox

。所以我不知道每个

TextBox

的大小，它可能不同，结果我的

pictureboxs

cover

TextBox

 static int k = 1;

 for (int att = 0; att < feed.response.items[i].attachments.Count(); att++)
 {
     string switchCase = feed.response.items[i].attachments[att].type;
     switch (switchCase)
     {
         case "photo":                                          
             TextBox text = new TextBox();
             text.Text =Encoding.UTF8.GetString(Encoding.Default.GetBytes(feed.response.items[i].text));
             Point p = new Point(20, 30 * k);
             text.Location = p;
             this.Controls.Add(text);

             PictureBox mypic = new PictureBox();
             mypic.ImageLocation =  feed.response.items[i].attachments[att].photo.photo_130;
             mypic.Size = new Size(100, 100);
             Point g = new Point(40, 160 * k);
             mypic.Location = g;
             this.Controls.Add(mypic);
             k++;
             break;
....
    }
}

static int k=1；
对于（int att=0；att

如所示，您可以使用两个TableLayoutPanel，其中一个在设计时添加到表单中。另一个是动态创建的，并使用正确的控件填充，以实现所需的功能。您的代码如下所示：

private void AddOne()
{
    // create a new tablelayoutpanel
    // with 2 rows, 1 column
    var table = new TableLayoutPanel();
    table.RowCount = 2;
    table.RowStyles.Add(new RowStyle());
    table.RowStyles.Add(new RowStyle());
    table.ColumnCount = 1;
    table.Dock = DockStyle.Fill; // take all space

    // create a label, notice the Anchor setting
    var lbl = new Label();
    lbl.Text = "lorem ipsum\r\nnext line\r\nthree";
    lbl.Anchor = AnchorStyles.Left | AnchorStyles.Right;
    lbl.AutoSize = true;
    // add to the first row
    table.Controls.Add(lbl, 0, 0);

    // create the picturebox
    var pict = new PictureBox();
    pict.Image = Bitmap.FromFile(@"demo.png");
    pict.Anchor = AnchorStyles.Left | AnchorStyles.Right;
    pict.SizeMode = PictureBoxSizeMode.Zoom;
    // add to the second row
    table.Controls.Add(pict, 0, 1);

    //add the table to the main table that is on the form
    mainTable.Controls.Add(table, 0, mainTable.RowCount);
    // increase the rowcount...
    mainTable.RowCount++;

}

您将使用和属性以及AutoSize属性让框架的布局引擎为您完成所有繁重的工作

您将得到如下结果：

private void AddOne()
{
    // create a new tablelayoutpanel
    // with 2 rows, 1 column
    var table = new TableLayoutPanel();
    table.RowCount = 2;
    table.RowStyles.Add(new RowStyle());
    table.RowStyles.Add(new RowStyle());
    table.ColumnCount = 1;
    table.Dock = DockStyle.Fill; // take all space

    // create a label, notice the Anchor setting
    var lbl = new Label();
    lbl.Text = "lorem ipsum\r\nnext line\r\nthree";
    lbl.Anchor = AnchorStyles.Left | AnchorStyles.Right;
    lbl.AutoSize = true;
    // add to the first row
    table.Controls.Add(lbl, 0, 0);

    // create the picturebox
    var pict = new PictureBox();
    pict.Image = Bitmap.FromFile(@"demo.png");
    pict.Anchor = AnchorStyles.Left | AnchorStyles.Right;
    pict.SizeMode = PictureBoxSizeMode.Zoom;
    // add to the second row
    table.Controls.Add(pict, 0, 1);

    //add the table to the main table that is on the form

尝试使用google并搜索如何将控件动态添加到表单winforms C#我会使用gridlayout来处理这类东西，您可能需要将

ColumnCount

属性设置为

1

。如果没有这一点，很难说清楚，不要介意用代码示例提供有用的答案。尝试使用google并搜索如何将控件动态添加到窗体winforms C#如果
