c# win App 中 Visual Basic Power Pack 工具中线条形状的标签

Question

Line shape是VisualBasic power pack 1.0（在vs2010中）的工具之一，

当我将标签属性添加到容器控件时，如何定义标签属性并为其设置值：

我的代码低于并且（在设计时）需要

public class MyLine:Microsoft.VisualBasic.PowerPacks.LineShape
{
    public Label label ;
    public MyLine()
    {
    }       
    public MyLine(ShapeContainer container)
        : base(container)
    {
        label = new Label() { Text = "Ali_Sarshogh" };
    }
}

///--------- 以主表单调用：

private Microsoft.VisualBasic.PowerPacks.ShapeContainer shapeContainer1;

 //--- in Button1_Click() i want to draw it :
  MyLine lineShape1 = new MyLine(shapeContainer1);
        lineShape1.Name = "lineShape1";
        lineShape1.X1 = 25;
        lineShape1.X2 = 160;
        lineShape1.Y1 = 18;
        lineShape1.Y2 = 17;
 this.shapeContainer1.Shapes.Add(lineShape1);

结果：表格上画线但标签不可见

Answer 1

给标签一个大小和位置，并将它也添加到控件中。比如：

public MyLine(ShapeContainer container) : base(container)
{
    label = new Label() { Text = "Ali_Sarshogh" };
    label.Location = new Point(0, 0);
    label.Size = new Size(100, 14);
    this.Controls.Add(label);
}

查看您创建的表单的任何 Designer.cs 文件，您将了解 IDE 是如何执行此操作的。
