跪求各位大神帮我看看哪错了吧基于asp.net开发的，数据库是sqlserver2005.无法将信息添加到数据库中。添加按钮click事件代码如下：protectedvoidButton1_Click
跪求各位大神帮我看看哪错了吧
基于asp.net的，数据库是 server2005.无法将信息添加到数据库中。
添加按钮click事件代码如下：
protected void Button1_Click(object sender, EventArgs e)
sql = "insert into shipinxinxi(mingcheng,leibie,danjia) values('"+mingcheng.Text.ToString().Trim() + "','"+leibie.Text.ToString().Trim() + "','"+danjia.Text.ToString().Trim() + "') ";
result = new Class1().hsgexucute(sql);
if (result == 1)
Response.Write("javascript:alert('添加成功');");
Response.Write("javascript:alert('系统错误，请检查数据库设置问题');");
Class1.cs中代码如下：
using System.D
//using System.Data.OleDb;
using System.Data.SqlC
using System.C
using System.W
using System.Web.S
using System.Web.UI;
using System.Web.UI.WebC
using System.Web.UI.WebControls.WebP
using System.Web.UI.HtmlC
/// Class1 的摘要说明
public class Class1
//SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings["testConnectionString"]);
public Class1()
// TODO: 在此处添加构造函数逻辑
// public static string connstring = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + System.Web.HttpContext.Current.Server.MapPath("~/App_Data/web.mdb");
public static string connstring = ConfigurationManager.AppSettings["cn"];
//设置连接数据库的代码是webconfig里面的cn那句,即:server=.;database=net05uid=pwd=;
public static DataSet GDS(string sql)
//OleDbDataAdapter dap = new OleDbDataAdapter(sql, connstring);
SqlDataAdapter dap = new SqlDataAdapter(sql, connstring);
DataSet ds = new DataSet();
dap.Fill(ds);
public static void Dsql(string sql)
OleDbConnection conn = new OleDbConnection();
SqlConnection conn = new SqlConnection();
conn.ConnectionString =
conn.Open();
OleDbCommand cmd = new OleDbCommand(sql, conn);
SqlCommand cmd = new SqlCommand(sql, conn);
cmd.ExecuteNonQuery();
conn.Close();
public int hsgexucute(string sql)
//自定义函数:执行sql语句,如果执行成功,返回值1,否则0
//myConnection.Open();
SqlConnection conn = new SqlConnection();
//定义新数据库连接
conn.ConnectionString =
//设置该新连接字符串是connstr,即上面的webconfig里的cn值
SqlCommand myCommand = new SqlCommand(sql, conn); //设置新执行命令
// SqlCommand cmd = new SqlCommand(sql, conn);
conn.Open();
//打开数据库连接
myCommand.ExecuteNonQuery(); //执行sql语句
//执行成功,返回1
//Console.WriteLine("SqlException:{0}",SQLexc);
//执行失败,返回0
conn.Close(); //关闭数据库连接
每次点击添加按钮，就会弹出提示框显示'系统错误，请检查数据库设置问题'，这是怎么回事呢？
牛头不对马嘴！
连接错误看 SqlConnection.Open 方法的帮助啊！
或者到找和你匹配的方式。
