自己编写SqlHelper，大家参考使用吧

复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Data; using System.Data.SqlClient;

namespace SqlHelper
{
/// <summary>
/// Window1.xaml 的交互逻辑
/// </summary>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}

//只用来执行查询结果比较少的sql
private void btnds_Click(object sender, RoutedEventArgs e)
{
SqlHelper.ExecuteNonQurey("insert into T_Student(Name,Age) values('张三',55)",
new SqlParameter[0]);
MessageBox.Show("添加成功");
}

private void btnDataSet_Click(object sender, RoutedEventArgs e)
{
DataSet ds= SqlHelper.ExecuteDataSet("select * from T_Student where hobbit='@hobbit'",
new SqlParameter[]{new SqlParameter("'@hobbit'","哈哈哈")});
foreach(DataRow row in ds.Tables[0].Rows)
{
string name = (string)row["Name"];
MessageBox.Show(name);
}
}
}
}
