【源代码的实现】

登录模块

登录模块根据用户角色不同在登陆成功以后被赋予相应的操作权限，对管理系统有对进货商品的录入、销售商品的录入等一些操作权限。 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; using System.Data.SqlClient;

namespace csharp {

public partial class Form1 : Form {

public Form1() {

InitializeComponent(); }

private void button2_Click(object sender, EventArgs e) {

}

private void button1_Click(object sender, EventArgs e) {

SqlConnection con = new

SqlConnection(\); con.Open(); SqlDataAdapter da = new SqlDataAdapter(\* from log where name='\ + textBox1.Text.Trim() + \ + textBox2.Text.Trim() + \, con); DataSet ds = new DataSet(); da.Fill(ds);

if (ds.Tables[0].Rows.Count == 0) {

MessageBox.Show(\用户名和密码有误.请重新输入\, \系统提示\, MessageBoxButtons.OK, MessageBoxIcon.Error); return; }

Form10 f10 =new Form10(); f10.Show(); this.Hide(); }

private void Form1_Load(object sender, EventArgs e) {

} } }
