嗨,,, lineto和moveto是c和c ++在graphics.h库中的图形方法,,,我想在ac＃中使用这些方法，请帮帮我

,,lineto and moveto are a graphical method in c and c++ in graphics.h library,,,i wanna to use these methods in a c#,,,please help me

推荐答案

请参阅 控制台.SetCursorPosition（） [ ^ ]。 除此之外，您需要使用Console.Write（）来编写行的每个字符。



对于Windows窗体，使用 Graphics.DrawLine（） [< a href =http://msdn.microsoft.com/en-us/library/system.drawing.graphics.drawline(v=vs.90).aspxtarget =_ blanktitle =New Window> ^ ]

See Console.SetCursorPosition()[^].  Other than that you'll need to use Console.Write() to write each character of your line.

For Windows Forms, use Graphics.DrawLine()[^]

使用基于使用Paint事件的C＃本机绘图工具的替代方法，是获取Visual Basic PowerPacks线和形状控件：[ ^ ]。



使用这些工具，您无需明确关注笔，画笔，图形对象等。 />


这里有一个关于如何使用它们的教程：[ ^ ]。



这是C＃中使用VB PowerPack LineShape的代码示例使用Microsoft.VisualBasic.PowerPacks绘制一条红色对角线，宽度为4像素，宽度为4像素，从左到右，形状为900,600：

An alternative to using C#'s native drawing facility which is based on using the Paint Event, is to get the Visual Basic PowerPacks "Line and Shape" controls: [^].

Using those tools, you do not need to explicitly concern yourself with pens, brushes, graphic objects, etc.

There's a tutorial on how to use them here: [^].

Here's an example of code in C# that uses the VB PowerPack LineShape facility to draw a red diagonal line 4 pixels in width from the top, left to bottom, right of a Form of size 900,600:

// required
using Microsoft.VisualBasic.PowerPacks;
//
// somewhere in your code ...
ShapeContainer canvas = new ShapeContainer();
canvas.Parent = this;
LineShape aLine = new LineShape(0, 0, 900, 600);
aLine.Parent = canvas;
aLine.BorderStyle = System.Drawing.Drawing2D.DashStyle.Solid;
aLine.BorderWidth = 4;
aLine.BorderColor = Color.Red;
aLine.Click += aLine_Click;

通过定义Click EventHandler：

By defining a Click EventHandler:

private void aLine_Click(object sender, EventArgs e)
{
    MessageBox.Show("aLine clicked");
}

我们现在有一条可点击的行，如果有必要，你可以通过一些技巧（通常用于在表格上制作其他控件的技术）完全适用于线条和形状对象）。



请注意，Line总是在后面的上绘制所有其他控件：调用BringToFront（）就不会导致错误，但不会产生任何影响。



在CodeProject上发表声明表示你无法成功继承Form或UserControl具有使用VB PowerPack工具创建的线条或形状，并使线条或形状起作用。我已经验证你确实可以使用VB工具从UserControl继承，并且继承控件中的行和形状工作。



你可能会采取如果您希望深入研究.NET中的绘图形状，请查看Erdal Halici 2013年关于CP的文章：[ ^ ]。



是否使用VB工具的成本（内存，性能）在你的C＃应用​​程序中绘图是可接受的是你可以决定的东西。



我会选择只在我想持久的时候使用VB工具用户可以在运行时与交互的图形对象。

We now have a "clickable" line, and a line you could, if necessary, make movable by some trickery (the techniques commonly used to make other Controls on a Form movable don't quite work with the line and shape objects).

Note that the Line is always drawn on the Form behind all other Controls: calling BringToFront() on it will not cause an error, but will have no effect.

Statements have been made on CodeProject that you cannot successfully inherit from a Form or UserControl which has lines, or shapes, created with the VB PowerPack Tools, and have the lines, or shapes, "work." I have verified that you can, indeed, inherit from a UserControl using the VB Tools, and the lines and shapes "work" in the inheriting Control.

You might take a look at Erdal Halici's 2013 article here on CP if you wish to go deeply into drawing shapes in .NET: [^].

Whether the "cost" (memory, performance) of using the VB tools for drawing in your C# application is acceptable is something only you can decide.

I would choose to use the VB Tools only when I wanted persistent graphic objects the user could interact with at run-time.
