本文实例为大家分享了C#实现餐饮管理系统的具体代码,供大家参考,具体内容如下

此系统采用C#语言的Winfrom和ADO.NET技术搭建的简单的CS系统。

部分代码:

frmBook.cs

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;

    {
      string Filter = " WHERE 1 = 1 ";

      if (txtName.Text.Trim() != "")
      {
        Filter += " AND Name Like '%" + txtName.Text + "%'";

      }

      BookEntity book = new BookEntity();
      DataTable dt = book.Query(Filter);
      this.dataGridView1.DataSource = dt;

      for (int i = 1; i < this.dataGridView1.Columns.Count; i++)
      {
        this.dataGridView1.Columns[i].ReadOnly = true;
      }

    }

    private void frmBook_Load(object sender, EventArgs e)

    }

    //全选
    private void btnChose_Click(object sender, EventArgs e)
    {
      bool b = false;
      if (btnChose.Text == "全 选")
      {

      }

      for (int i = 0; i < this.dataGridView1.Rows.Count; i++)
      {
        dataGridView1.Rows[i].Cells[0].Value = b;
      }
      this.dataGridView1.EndEdit();
      this.dataGridView1.CurrentCell = null;

      getData();
    }

    //查询
