ASP.net调用数据库

其实ASP.NET中 WEB调用数据库的方法和在c#桌面应用上一样

下面是我做的登陆注册的代码 大家可以参考一下

protected void btnClick(object sender, EventArgs e)

{

if (this.yong.Value=="")

{

Response.Write("请输入用户名");

}

else

{

if (this.mi2.Value==mi1.Value)

{

if (Radio1.Checked)

{

if (File1.Value=="")

{

Response.Write ("请上传头像");

}

else

{

string s1 = yong.Value;

string s2 = mi1.Value;

string str = "insert into yonghu3(yonghu,mima)VALUES('" + s1 + "','" + s2 + "')";

SqlConnection con = new SqlConnection();

con.ConnectionString = "server=刘宁-PC;Integrated Security=true; Initial Catalog=liaotian";

SqlCommand cmd = new SqlCommand(str, con);

con.Open();

SqlDataReader myreader;

myreader = cmd.ExecuteReader();

Response.Write("注册成功");

con.Close();

}

}

else

{

Response.Write("选择你的性别");

}

}

else

{

Response.Write("密码输入不一致");

}

}
