## 场景 ##

Winform控件-DevExpress18下载安装注册以及在VS中使用：

在使用ZedGraph进行添加曲线时，曲线数量如果很多的情况下，速度会比较慢。

所以在进行添加曲线的过程中需要显示进度，效果如下

## 实现 ##

在当前要添加进度条的页面打开设计器，并在安装了DevExpress的工具箱中拖拽一个ProgressBarControl

然后在当前窗体的构造方法中进行进度条控件的一些属性设置

public FrmCurveCompareInOne()
            {
                InitializeComponent();
                progressBarControl1.Visible = true;
                //设置一个最小值
                progressBarControl1.Properties.Minimum = 0;
                //设置一个最大值
                progressBarControl1.Properties.Maximum = 100;
                //设置进度条的样式
                progressBarControl1.Properties.ProgressViewStyle = DevExpress.XtraEditors.Controls.ProgressViewStyle.Solid;
                //当前值
                progressBarControl1.Position = 0;
                //是否显示进度数据
                progressBarControl1.Properties.ShowTitle = true;
                //是否显示百分比
                progressBarControl1.Properties.PercentView = true;
              
            }

然后在触发显示进度条的方法中传递当前进度条对象

ChartCompareHelper.RefreshPaneComInOne(this.zedGraphControl1, xYModelStore.YAxisModelList,this.progressBarControl1);

在上面刷新ZedGraph的图形的方法中，添加曲线的部分进行进度的设置

if (yList != null && yList.Count > 0)
                {
                    PointPairList list = null;
                    for (int i = 0; i < yList.Count; i++)
                    {
                        //截取前100个循环进行显示
                        Global.Instance.PrepareCompareDataInOne = Global.Instance.PrepareCompareDataInOne.Where(p => (int.Parse(p.Id) < 101)).ToList();
                        //计算进度条步长
                        int step = 1;
                        //曲线总数小于100
                        if (Global.Instance.PrepareCompareDataInOne.Count < 100)
                        {
                            step = 100 / Global.Instance.PrepareCompareDataInOne.Count;
                        }
                        else
                        {
                            step = Global.Instance.PrepareCompareDataInOne.Count / 100;
                        }
                        if(progressBar !=null)
                        {
                            //将进度条初始化为0%
                            progressBar.Position = 0;
                        }
                        //循环添加曲线
                        foreach(DataTreeNode node in Global.Instance.PrepareCompareDataInOne)
                        {
                            IEnumerable<Entity.Record> record =  Global.Instance.VirtualData.RecordDataList.Where(p => p.CycleIndex == int.Parse(node.Id));
                            list = SetCurveTextInOne(yList[i].TitleKey,record);
                            LineItem myCurve = myPane.AddCurve(yList[i].Title, list, System.Drawing.ColorTranslator.FromHtml(yList[i].Color), SymbolType.None);
                            myCurve.YAxisIndex = i;                                                                 //很关键，对应使用那个坐标值
                            if(progressBar !=null)
                            {
                                //添加成功一条曲线则进度条增加一个步数
                                progressBar.Position += step;
                                if (progressBar.Position >=100)
                                {
                                    //如果总进度已经大于100了 则赋值为100
                                    progressBar.Position = 100;
                                }
                                //更新进度条的进度
                                progressBar.Update();
                            }
                        }
                        if (progressBar != null)
                        {
                            //最终添加完所有曲线后将进度条设置为100%
                            progressBar.Position = 100;
                        }
                    }
