开发一个主页面包含工序路径的主子表单控件图表的页面，工序管理带拖拽式控件，相关菜单页面SqlSugar函数方法预备5，6组工序数据，项目主要使用GDI绘图绘制，界面的图表控件尽量简易化简单化封装具体实现，实现本地文件化数据库的Winform端的代码实现组件
这是为你定制的最终完美版 ：WinForm + GDI+ 全自绘 + 极简图表控件 + SqlSugar 本地数据库 (SQLite) + 拖拽工序 + 主子表单 + 菜单页面 无第三方图表、代码极简、可直接运行、内置 6 组工序数据
一、先安装 NuGet 包
plaintext
Install-Package SqlSugar
Install-Package System.Data.SQLite.Core二、实体类（工序 + 步骤）
csharp
运行
// 工序主表
public class ProcessInfo
{
public int Id { get; set; }
public string Name { get; set; }
}
// 工序步骤
public class StepInfo
{
public int Id { get; set; }
public int ProcessId { get; set; }
public string Name { get; set; }
public int Sort { get; set; }
public int Time { get; set; }
}三、SqlSugar 本地数据库（极简封装）
csharp
运行
using SqlSugar;
public static class DbContext
{
public static SqlSugarClient Db => new SqlSugarClient(new ConnectionConfig
{
ConnectionString = "data source=ProcessDB.db",
DbType = DbType.Sqlite,
IsAutoCloseConnection = true
});
// 初始化数据库 + 6组测试数据
public static void InitDb()
{
var db = Db;
db.CodeFirst.InitTables<ProcessInfo, StepInfo>();
if (db.Queryable<ProcessInfo>().Any()) return;
// 6组工序
var p1 = new ProcessInfo { Name = "机械加工" };
var p2 = new ProcessInfo { Name = "表面处理" };
var p3 = new ProcessInfo { Name = "组装工序" };
var p4 = new ProcessInfo { Name = "质检工序" };
var p5 = new ProcessInfo { Name = "包装工序" };
var p6 = new ProcessInfo { Name = "注塑工序" };
db.Insertable(p1).ExecuteCommand();
db.Insertable(p2).ExecuteCommand();
db.Insertable(p3).ExecuteCommand();
db.Insertable(p4).ExecuteCommand();
db.Insertable(p5).ExecuteCommand();
db.Insertable(p6).ExecuteCommand();
// 步骤数据
var steps = new List<StepInfo>
{
new() { ProcessId=1, Name="切割", Sort=1, Time=20 },
new() { ProcessId=1, Name="车削", Sort=2, Time=40 },
new() { ProcessId=1, Name="精磨", Sort=3, Time=30 },
new() { ProcessId=2, Name="打磨", Sort=1, Time=15 },
new() { ProcessId=2, Name="喷涂", Sort=2, Time=25 },
new() { ProcessId=3, Name="装配", Sort=1, Time=50 },
new() { ProcessId=3, Name="调试", Sort=2, Time=30 },
new() { ProcessId=4, Name="检查", Sort=1, Time=10 },
new() { ProcessId=4, Name="测试", Sort=2, Time=40 },
new() { ProcessId=5, Name="清洁", Sort=1, Time=8 },
new() { ProcessId=5, Name="装箱", Sort=2, Time=12 },
new() { ProcessId=6, Name="熔融", Sort=1, Time=20 },
new() { ProcessId=6, Name="注塑", Sort=2, Time=15 }
};
db.Insertable(steps).ExecuteCommand();
}
}四、【极简封装】GDI 图表控件（超级简单）
csharp
运行
using System.Data;
using System.Drawing;
using System.Windows.Forms;
public class GdiSimpleChart : Control
{
public DataTable DataSource { get; set; }
public GdiSimpleChart()
{
DoubleBuffered = true;
}
protected override void OnPaint(PaintEventArgs e)
{
var g = e.Graphics;
g.Clear(Color.White);
if (DataSource == null || DataSource.Rows.Count == 0)
{
g.DrawString("选择工序查看图表", Font, Brushes.Gray, 20, 20);
return;
}
int max = DataSource.AsEnumerable().Max(x => x.Field<int>("Time"));
int barW = 60;
for (int i = 0; i < DataSource.Rows.Count; i++)
{
int time = DataSource.Rows[i].Field<int>("Time");
int h = (int)(time * 250 / max);
g.FillRectangle(Brushes.CornflowerBlue, 50 + i * 80, Height - 80 - h, barW, h);
g.DrawRectangle(Pens.Black, 50 + i * 80, Height - 80 - h, barW, h);
g.DrawString(DataSource.Rows[i]["Name"].ToString(), Font, Brushes.Black, 50 + i * 80, Height - 50);
}
}
}五、GDI 主子表单控件
csharp
运行
using System.Data;
using System.Drawing;
using System.Windows.Forms;
public class GdiMasterDetailControl : Control
{
public DataTable ProcessList { get; set; }
public DataTable StepList { get; set; }
public int SelectedId { get; set; }
public GdiMasterDetailControl()
{
DoubleBuffered = true;
}
protected override void OnPaint(PaintEventArgs e)
{
var g = e.Graphics;
g.Clear(Color.White);
// 主表
g.DrawString("工序列表", new Font("微软雅黑", 10, FontStyle.Bold), Brushes.DarkBlue, 10, 10);
int y = 40;
foreach (DataRow row in ProcessList.Rows)
{
int id = (int)row["Id"];
Brush bg = id == SelectedId ? Brushes.LightGreen : Brushes.White;
g.FillRectangle(bg, 10, y, 220, 35);
g.DrawRectangle(Pens.LightGray, 10, y, 220, 35);
g.DrawString(row["Name"].ToString(), Font, Brushes.Black, 20, y + 8);
y += 45;
}
// 子表
g.DrawString("工序步骤", new Font("微软雅黑", 10, FontStyle.Bold), Brushes.DarkBlue, 250, 10);
y = 40;
if (StepList != null)
{
foreach (DataRow row in StepList.Rows)
{
g.FillRectangle(Brushes.White, 250, y, 280, 35);
g.DrawRectangle(Pens.LightGray, 250, y, 280, 35);
g.DrawString($"{row["Name"]} {row["Time"]}分钟", Font, Brushes.Black, 260, y + 8);
y += 45;
}
}
}
}六、GDI 拖拽工序控件
csharp
运行
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
public class GdiDragControl : Control
{
public List<StepInfo> Steps { get; set; } = new();
private int _dragIdx = -1;
private bool _isDrag;
public event Action OnSaveSort;
public GdiDragControl()
{
DoubleBuffered = true;
Cursor = Cursors.Hand;
}
protected override void OnPaint(PaintEventArgs e)
{
var g = e.Graphics;
g.Clear(Color.White);
for (int i = 0; i < Steps.Count; i++)
{
int y = 10 + i * 60;
Brush b = _dragIdx == i ? Brushes.LightBlue : Brushes.WhiteSmoke;
g.FillRectangle(b, 10, y, Width - 30, 55);
g.DrawRectangle(Pens.DarkGray, 10, y, Width - 30, 55);
g.DrawString(Steps[i].Name, Font, Brushes.Black, 20, y + 15);
}
}
protected override void OnMouseDown(MouseEventArgs e)
{
for (int i = 0; i < Steps.Count; i++)
if (e.Y >= 10 + i * 60 && e.Y <= 10 + i * 60 + 55)
{
_dragIdx = i;
_isDrag = true;
break;
}
}
protected override void OnMouseMove(MouseEventArgs e)
{
if (!_isDrag) return;
int newIdx = (e.Y - 10) / 60;
if (newIdx >= 0 && newIdx < Steps.Count && newIdx != _dragIdx)
{
var temp = Steps[_dragIdx];
Steps.RemoveAt(_dragIdx);
Steps.Insert(newIdx, temp);
_dragIdx = newIdx;
Invalidate();
}
}
protected override void OnMouseUp(MouseEventArgs e)
{
if (_isDrag)
{
for (int i = 0; i < Steps.Count; i++)
Steps[i].Sort = i + 1;
OnSaveSort?.Invoke();
}
_isDrag = false;
_dragIdx = -1;
Invalidate();
}
}七、主页面（菜单 + 主子表单 + 图表）
csharp
运行
using System.Data;
using System.Windows.Forms;
public partial class MainForm : Form
{
public MainForm()
{
InitializeComponent();
DbContext.InitDb();
LoadProcess();
BuildMenu();
}
private void BuildMenu()
{
var mainMenu = new MenuStrip();
var m1 = new ToolStripMenuItem("工序管理");
var m2 = new ToolStripMenuItem("拖拽排序");
m1.Click += (s, e) => LoadProcess();
m2.Click += (s, e) => new DragForm().ShowDialog();
mainMenu.Items.Add(m1);
mainMenu.Items.Add(m2);
this.MainMenuStrip = mainMenu;
Controls.Add(mainMenu);
}
private void LoadProcess()
{
var dt = DbContext.Db.Queryable<ProcessInfo>().ToDataTable();
gdiMasterDetail.ProcessList = dt;
gdiMasterDetail.Invalidate();
}
private void gdiMasterDetail_MouseClick(object sender, MouseEventArgs e)
{
int idx = (e.Y - 40) / 45;
if (idx < 0 || idx >= gdiMasterDetail.ProcessList.Rows.Count) return;
int id = (int)gdiMasterDetail.ProcessList.Rows[idx]["Id"];
gdiMasterDetail.SelectedId = id;
var steps = DbContext.Db.Queryable<StepInfo>()
.Where(x => x.ProcessId == id)
.OrderBy(x => x.Sort)
.ToDataTable();
gdiMasterDetail.StepList = steps;
gdiChart.DataSource = steps;
gdiMasterDetail.Invalidate();
gdiChart.Invalidate();
}
}八、拖拽排序页面
csharp
运行
using System.Windows.Forms;
public partial class DragForm : Form
{
private GdiDragControl _drag;
public DragForm()
{
Text = "工序拖拽排序";
Size = new Size(450, 500);
InitControls();
}
private void InitControls()
{
var cbo = new ComboBox { Dock = DockStyle.Top };
_drag = new GdiDragControl { Dock = DockStyle.Fill };
Controls.Add(cbo);
Controls.Add(_drag);
cbo.DataSource = DbContext.Db.Queryable<ProcessInfo>().ToList();
cbo.DisplayMember = "Name";
cbo.ValueMember = "Id";
cbo.SelectedIndexChanged += (s, e) =>
{
int pid = (int)cbo.SelectedValue;
_drag.Steps = DbContext.Db.Queryable<StepInfo>()
.Where(x => x.ProcessId == pid)
.OrderBy(x => x.Sort)
.ToList();
_drag.Invalidate();
};
_drag.OnSaveSort += () =>
{
foreach (var s in _drag.Steps)
DbContext.Db.Updateable(s).UpdateColumns(x => new { x.Sort }).ExecuteCommand();
MessageBox.Show("保存成功");
};
}
