Question

c# 鼠标获取坐标。怎么在鼠标 箭头上出现坐标。比如箭头上显示（X,Y）。

Answer 1

我这是Winform版本的，就是在Form窗体中加：ToolTip控件， 然后在Form中的MouseMove事件中加：
toolTip1.Show("" + e.X + ";" + e.Y, this, new Point(e.X, e.Y));
就完了。。。

页面代码：
namespace WindowsFormsApplication1
{
partial class Form1
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;

/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

#region Windows Form Designer generated code

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
this.label1 = new System.Windows.Forms.Label();
this.toolTip1 = new System.Windows.Forms.ToolTip(this.components);
this.SuspendLayout();
//
// label1
//
this.label1.AutoSize = true;
this.label1.Location = new System.Drawing.Point(227, 106);
this.label1.Name = "label1";
this.label1.Size = new System.Drawing.Size(41, 12);
this.label1.TabIndex = 0;
this.label1.Text = "label1";
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(641, 382);
this.Controls.Add(this.label1);
this.Name = "Form1";
this.Text = "Form1";
this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseMove);
this.ResumeLayout(false);
this.PerformLayout();

}

#endregion

private System.Windows.Forms.Label label1;
private System.Windows.Forms.ToolTip toolTip1;
}
}

主要代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_MouseMove(object sender, MouseEventArgs e)
{
toolTip1.Show("" + e.X + ";" + e.Y, this, new Point(e.X, e.Y));
}
}
}

Answer 2

int x = Control.MousePosition.X;
int y = Control.MousePosition.Y;
Point p = new Point(x,y);
.net封装好的类

如何实现在鼠标 箭头上面显示。比如鼠标放在某个坐标上 一定时间无动作后，在箭头上显示（x,y）

追答

是做BS还是做CS 如果是BS的话 那就弹出一个层 层的location位置的P

追问

只是个简单的窗口程序。能不能实现

追答

那就用lable lable的location位置=point

追问

有没专门的API实现。

好的。我试下。

追答

有 不过这个我不懂 你可以baidu一下

追问

百度不知道。 谢谢。我试下
