C# 开源仪表盘库

1、简介

有个叫A.J.Bauer 的大神在System.Windows.Forms.Control类的基础上建立了一个显示各种仪表盘的类。

英文版简介：C# Tutorial, A gauge control with all source code, .net 2.0 http://ucancode.net/CSharp_Tutorial_GDI+_Gauge_Source_Code.htm

Github地址：Code-Artist/AGauge: C# Gauge Control https://github.com/Code-Artist/AGauge

安装包地址：NuGet Gallery | CodeArtEng.Controls 2.2.0 https://www.nuget.org/packages/CodeArtEng.Controls/

2、下载及安装

（1）使用VS自带的NuGet来安装

不清楚NuGet的童鞋可以参考这篇：真心好用的VS扩展--NuGet - 阿里云 https://www.aliyun.com/jiaocheng/624805.html

接下来，开始安装，打开安装包地址 https://www.nuget.org/packages/CodeArtEng.Controls/

可以看到支持package Manager 安装，只需输入下面指令：

Install-Package CodeArtEng.Controls -Version 2.2.0

先打开VS，进入Tools即工具选项卡，找到NuGet，打开其控制台

然后在控制台输入上面的指令：

成功安装后，就可以愉快的引用了。

（2）手动下载软件包并导入

在网站右侧有下载按钮，直接下载的包名称为 agauge_v2.2.0.2.nupkg

接下来添加本地的nuget包，可参考一下文章：

NuGet添加本地包(Package) - Hejin.Wong - 博客园 https://www.cnblogs.com/egger/archive/2013/03/19/2970138.html

进入工具(Tools)，最下面一行选项（Options），找到NugetPackageManager,在包来源处添加本地包所在的目录。

之后再进入Tools->NuGet，从设定好的package source 目录中选择我们的本地库进行导入。

3、新建winForm工程并添加Agauge

首先从github下载了Agauge的作者写的demo，里面是没有.sln文件的，打开csproj文件即可。

这个项目用vs2013打开之后是直接可以运行的，界面是一个仪表盘和一个滑动条，拖动滑动条可以改变仪表盘的指针。

为了快速编写自己的例子，我新建了一个C#的winForm工程，仪表盘的代码直接从demo

拷贝过来。我新建的工程放在了 https://github.com/sheep12345679/C-Agauge-Test.git

注意新建项目一定要使用Nuget导入agauge的package。

主要修改了MainForm.Designer.cs和MainForm.cs里的代码：

MainForm.Designer.cs中定义了使用的控件，同时在InitializeComponent()函数中对控件做了初始化。

private void InitializeComponent()

        {

            System.Windows.Forms.AGaugeLabel aGaugeLabel1 = new System.Windows.Forms.AGaugeLabel();

            this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Absolute, 50F));

            this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 100F));

            this.button2.UseVisualStyleBackColor = true;

            // MainForm

            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);

            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

            this.ClientSize = new System.Drawing.Size(, );

            //this.Controls.Add(this.aGauge1);

            //this.Controls.Add(this.panel1);

            //this.Controls.Add(trackBar1);

            //this.Controls.Add(this.button1);

            this.Controls.Add(tableLayoutPanel1);

            //this.Controls.Add(this.button2);

            this.Name = "MainForm";

            this.Text = "Form1";

            ((System.ComponentModel.ISupportInitialize)(this.trackBar1)).EndInit();

            this.panel1.ResumeLayout(false);

            this.tableLayoutPanel1.ResumeLayout(false);

            this.tableLayoutPanel1.PerformLayout();

            this.ResumeLayout(false);

        }

需要注意的是，在设置完控件的参数之后，不要忘了this.Controls.Add(tableLayoutPanel1); 这句话，否则控件无法显示在窗口上。

        private System.Windows.Forms.AGauge aGauge1;

        private System.Windows.Forms.TrackBar trackBar1;

        private System.Windows.Forms.Panel panel1;

        private System.Windows.Forms.TableLayoutPanel tableLayoutPanel1;

        private System.Windows.Forms.Button button1;

        private System.Windows.Forms.Button button2;

之后对MainForm.cs进行修改，定义操作控件的函数

//MainForm.cs

public partial class MainForm : Form

    {

        private System.Windows.Forms.AGaugeLabel label;

        private System.Windows.Forms.AGaugeRange alert;

        public MainForm()

        {

            InitializeComponent();

            label = aGauge1.GaugeLabels.FindByName("GaugeLabel1");

            alert = aGauge1.GaugeRanges.FindByName("AlertRange");

            aGauge1.ValueInRangeChanged += AGauge1_ValueInRangeChanged;

        }

        private void AGauge1_ValueInRangeChanged(object sender, ValueInRangeChangedEventArgs e)

        {

        }

        private void trackBar1_ValueChanged(object sender, EventArgs e)

        {

            aGauge1.Value = trackBar1.Value;

        }

        private void aGauge1_ValueChanged(object sender, EventArgs e)

        {

            label.Text = aGauge1.Value.ToString();

        }

        private void aGauge1_ValueInRangeChanged(object sender, System.Windows.Forms.ValueInRangeChangedEventArgs e)

        {

            System.Diagnostics.Debug.WriteLine("InRange Event.");

            if (e.Range == alert)

            {

                panel1.BackColor = e.InRange ? Color.Red : Color.FromKnownColor(KnownColor.Control);

            }

        }

        private void button1_Click(object sender, EventArgs e)

        {

            //aGauge1.GaugeRanges.RemoveAt(0);

            //aGauge1.GaugeRanges.Add(new AGaugeRange(Color.Blue, 40, 60, , ));

        }

    }
