自己写的实体类生成工具

懒人一个，所以不想做重复攻，自己一个小时写了个实体类生成工具。

没有美化，功能够用。（限SQLSERVER数据库）

不多说，上图上代码。

没什么高端的代码，就是拼接字符串而已~。

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;
using System.Data.SqlClient;
namespace 实体类代码生成工具
{
    public partial class Login : Form
    {
        public Login()
        {
            InitializeComponent();
        }

        private void BtnLogin_Click(object sender, EventArgs e)
        {
            string slm = txtSLM.Text.Trim();
            string user = txtName.Text.Trim();
            string pwd = txtPwd.Text.Trim();
            string sjk=txtSJK.Text.Trim();
            SqlConnectionStringBuilder sb = new SqlConnectionStringBuilder();
            sb.DataSource = slm;
            sb.InitialCatalog =sjk;
            sb.UserID = user;
            sb.Password = pwd;
            SqlConnection con = new SqlConnection(sb.ToString());
            try
            {
                con.Open();
                Main m = new Main(sb);
                m.Show();
            
            }
            catch (SqlException EX)
            {
                MessageBox.Show(EX.Message);
            }
            finally
            {
                con.Close();
                con.Dispose();
            }
        }

        private void BtnClose_Click(object sender, EventArgs e)
        {
            this.Close();
            this.Dispose();
        }
    }
}

 然后是主窗体

代码如下：

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 实体类代码生成工具
{
    public partial class Main : Form
    {
        SqlConnection con;
        SqlDataAdapter da;
        DataTable dt;
        string sqlstr;
        StringBuilder str = new StringBuilder();
        public Main(SqlConnectionStringBuilder builder)
        {
            sqlstr = builder.ToString();
            InitializeComponent();
        }

        private void Main_Load(object sender, EventArgs e)
        {
            dt = GetDataTableA("select name from sysobjects where xtype='U' order by name ");
            foreach (DataRow dr in dt.Select())
            {
                listBox1.Items.Add(dr[0]);
            }
        }

        /// <summary>
        /// 离线模式填充datatable并返回，数据少可以用此方法
        /// </summary>
        /// <param name="sql"></param>
        /// <returns></returns>
        public  DataTable GetDataTableA(string sql)
        {
            using (con = new SqlConnection(sqlstr))
            {
                da = new SqlDataAdapter(sql, con);
                da.MissingSchemaAction = MissingSchemaAction.AddWithKey;
                dt = new DataTable();
                da.Fill(dt);
                return dt;
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            richTextBox1.Text = "";
            if (String.IsNullOrEmpty(txtSpace.Text+txtclass.Text))
            {
                MessageBox.Show("NameSpace必须填写");
            }
            else
            {
        
                str.Append("using System;" + Environment.NewLine);
                str.Append("using System.Collections.Generic;" + Environment.NewLine);
                str.Append("using System.ComponentModel;"+Environment.NewLine);
                str.Append("using System.Data;"+Environment.NewLine);
                str.Append("using System.Text;"+Environment.NewLine);
                str.Append("namespace  " + txtSpace.Text + "  " + Environment.NewLine);
                str.Append("{" + Environment.NewLine);
                str.Append("     public  class "+txtclass.Text +Environment.NewLine);
                str.Append("       {" + Environment.NewLine);

                dt = GetDataTableA("select * from " + listBox1.Text + " where 1=2 ");
                foreach (DataColumn d in dt.Columns)
                {
                    if (d.AllowDBNull)
                    {
                        str.Append("          public  " + d.DataType.ToString() + "? " + d.ColumnName +"{get;set}" + Environment.NewLine);
                    }
                    else
                    {
                        str.Append("          public  " + d.DataType.ToString() + " " + d.ColumnName + "{get;set}" + Environment.NewLine);
                    }
                }
                str.Append("      }" + Environment.NewLine);
                str.Append("}" + Environment.NewLine);
                richTextBox1.Text = str.ToString();
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            Clipboard.SetData(DataFormats.Text,str.ToString() );//复制内容到剪切板
        }
    }
}

 OK..改一改字符串啥的。就能跑了。
