用WinForm寫的員工考勤項目！！！！！！

先說幾句，作為一個還在學習的程序員，掌握的知識有限；但我利用自身所學，給一些像我一樣還在學習的碼農提供我的綿薄之力！

寫的不好，但是盡力了，希望大牛指點。多多吐槽！！！

   好了開始說項目需求: 實現新增員工；使用DataGridView控件展示員工信息；實現根據員工工號進行模糊查詢；實現刪除員工信息；每天只能簽到一次；簽退前必須已經簽到

看到這些需求，我們先要思考下該做什么，理清思路才能更快的完成項目。我通常先搭建窗體，然后根據要求逐步實現項目要求！

這是我們所要用的到的三個窗體

我們建一個輔助類，初始化一個單列的泛型集合，給單列的泛型集合付個初值

 

class Worker
    {
        private string id;
        private string name;
        private int age;
        private string sex;
        public string ID
        {
            get
            {
                return id;
            }

            set
            {
                id = value;
            }
        }

        public string Name
        {
            get
            {
                return name;
            }

            set
            {
                name = value;
            }
        }

        public int Age
        {
            get
            {
                return age;
            }

            set
            {
                age = value;
            }
        }

        public string Sex
        {
            get
            {
                return sex;
            }

            set
            {
                sex = value;
            }
        }
        
        public static List<Worker> list = new List<Worker>();
        public static void Insert()
        {
            Worker w1 = new Worker();
            w1.ID = "20090101";
            w1.Name = "王小毛";
            w1.Age = 20;
            w1.Sex = "男";
            list.Add(w1);
            Worker w2 = new Worker();
            w2.ID = "20090102";
            w2.Name = "周新雨";
            w2.Age = 19;
            w2.Sex = "女";
            list.Add(w2);
        }
    }

　這是員工信息維護窗體的Load事件的代碼

 private void FrmSecond_Load(object sender, EventArgs e)
        {
如果list沒有數據就添加數據，確保調用這個窗體是，只有在沒有數據時才能添加數據！
            if (Worker.list.Count==0)
            {
                Worker.Insert();
            }
清除datagridview的英文列，並且綁定數據
            dgvList.AutoGenerateColumns = false;
            dgvList.DataSource = Worker.list;
        }

　這是新增里的代碼

private void toolStripButton1_Click(object sender, EventArgs e)
        {
調用添加員工員工信息窗體
            FrmFirst ff = new FrmFirst();
            this.Hide();
            ff.Show();
        }

private void btn1_Click(object sender, EventArgs e)
        {
確保一個工號只能添加一次
            foreach (Worker item in Worker.list)
            {
                if (item.ID==txt01.Text)
                {
                    MessageBox.Show("工號已存在！！！！");
                    return;
                }
               
            }
添加一個員工信息
            Worker w1 = new Worker();
            w1.ID = txt01.Text;
            w1.Name = txt03.Text;
            w1.Age = Convert.ToInt32(txt02.Text);
            w1.Sex =cob01.Text;
            Worker.list.Add(w1);
            FrmSecond fs = new FrmSecond();
            this.Close();
            fs.Show();

        }

　

這是刪除的代碼
private void toolStripButton3_Click(object sender, EventArgs e)
        {
提示點擊是才會刪除
            DialogResult result = MessageBox.Show("提示","是否刪除",MessageBoxButtons.YesNo,MessageBoxIcon.Question);
            if(result==DialogResult.Yes)
            {

                string id = dgvList.SelectedRows[0].Cells[0].Value.ToString();
                //string id = dgvList.SelectedCells[0].Value.ToString();
如果ID和我選中的ID相等才會刪除
                foreach (Worker item in Worker.list)
                {
                       if(item.ID==id)
                      {
                        Worker.list.Remove(item);
                        break;
                      }
                }
            }
            //dgvList.AutoGenerateColumns = false;
            dgvList.DataSource = new BindingList<Worker>(Worker.list);

        }

　

這段是重點難點在寫這段之前先建好另一個輔助類
  class Record
    {
        public string id { get; set; }
        public string name { get; set; }
        public DateTime SignInTime { get; set; }
        public DateTime SignOutTime { get; set; }
        創建一個雙列泛型集合
        public static Dictionary<string, Record> relist = new Dictionary<string, Record>();
       
    }
 
public int num;
        private void 簽到ToolStripMenuItem_Click(object sender, EventArgs e)
        {
給num賦值，把你選中的type值付給num
            Worker w = new Worker();
            foreach (Worker item in Worker.list)
            {
                if (item.Name == dgvList.SelectedCells[1].Value.ToString())
                {
                    w = item;
                    break;
                }
            }
            num = w.type;
判斷如果num是0才可以簽到
            if (num == 0)
            {
                Record r = new Record();
                r.id = dgvList.SelectedRows[0].Cells[0].Value.ToString();
                r.name = dgvList.SelectedRows[0].Cells[1].Value.ToString();
                r.SignInTime = DateTime.Now;
                Record.relist.Add(r.name, r);
給你選中的type賦值一個1
                w.type = 1;
                MessageBox.Show("簽到成功");
            }
            else
            {
                MessageBox.Show("您已經簽到過了");
            }
        }

        private void 簽退ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            Worker w = new Worker();
            foreach (Worker item in Worker.list)
            {
                if (item.Name == dgvList.SelectedCells[1].Value.ToString())
                {
                    w = item;
                    break;
                }
            }
把你選中的type賦值給num
            num = w.type;
如果num是1，才可以簽退
            if (num == 1)
            {
                foreach (string item in Record.relist.Keys)
                {
                    if (item == dgvList.SelectedRows[0].Cells[1].Value.ToString())
                    {
                        Record.relist[dgvList.SelectedRows[0].Cells[1].Value.ToString()].SignOutTime = DateTime.Now;
                        w.type = 2;
                        MessageBox.Show("簽退成功");
                        break;
                    }
                }
            }
如果是0證明沒有簽到
            else if (num == 0)
            {
                MessageBox.Show("沒有簽到，無法簽退");

            }
否則已經簽退過了
            else
            {

                MessageBox.Show("您已經簽退過了");
            }

        //dgvList.AutoGenerateColumns = false;
        //dgvList.DataSource = new BindingList<Worker>(Worker.list);
    }

　　

把員工的簽到信息展示在DataGridView上

private void FrmThisd_Load(object sender, EventArgs e)
        {
            dgvList.AutoGenerateColumns = false;
            BindingSource bs = new BindingSource();
            bs.DataSource = Record.relist.Values;
            dgvList.DataSource = bs;

            lbl1.Text = dgvList.RowCount.ToString();
        }
