Writing data and saving to a SQL Server database using C# and ASP.NET
Question
I'm pretty new to C#, what I want to do is have the user enter data into fields and when they hit submit it writes to a database. I'm really stuck any help would be much appreciated.
Here is what I have so far.
My markup:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Registration.aspx.cs" Inherits="subscribe_Registration" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Your Earth, Your Home.</title>
<link rel="stylesheet" type="text/css" href="../StyleSheet.css" />
</head>
<body>
<form id="form1" runat="server">
<div class="container">

public string Email { get; set; }
public int Phone { get; set; }
}
}
I'm really stuck I'm not exactly sure where to go from here. I want to save the user data into a database. Not sure whats the best way or where to start. If you could at least point me in the right direction any help would be much appreciated.
Thanks in advance :)

you should use breakpoints in your .cs code. most common mistake in this kind of program is that name of the field in database or .cs file are slightly different, b'coz of that server did not get the value for every field in your database. this gives an error.
So proper use of breakpoints and use debugger to debugg your program, so that u found at which point u got an error.

1.Create a Users table in SQL for storing user data and a stored procedure to insert into this table:
CREATE PROCEDURE [dbo].[Procedure]
@Name VARCHAR(50),
@Age VARCHAR(50),
@Sex VARCHAR(50),
@Address VARCHAR(50),
@Email VARCHAR(100),
@Phone VARCHAR(100)
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO Users(Name,Age,Sex,[Address],Email,Phone)
VALUES(@Name,@Age,@Sex,@Address,@Email,@Phone)
END
GO
2.Change the code behind file like this:
protected void Button1_Click(object sender, EventArgs e)
{
var reg = new Registration.Registration
{
Name = txtName.Text,
Age = Int32.Parse(txtAge.Text),
Sex = txtSex.Text,
Address = txtAddress.Text,
Email = txtEmail.Text,
Phone = Int32.Parse(txtPhone.Text)
};
this.InsertRegistration(reg);
phSuccess.Visible = true;
}
public void InsertRegistration(Registration.Registration reg)
{
try
{
using (var conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Database"].ConnectionString))
{
using (var cmd = new SqlCommand("dbo.Procedure", conn))
{
cmd.CommandType = CommandType.StoredProcedure;
var parameterName = new SqlParameter("@Name", SqlDbType.VarChar, 50);
var parameterAge = new SqlParameter("@Age", SqlDbType.VarChar, 50);
var parameterSex = new SqlParameter("@Sex", SqlDbType.VarChar, 50);
var parameterAddress = new SqlParameter("@Address", SqlDbType.VarChar, 50);
var parameterEmail = new SqlParameter("@Email", SqlDbType.VarChar, 100);
var parameterPhone = new SqlParameter("@Phone", SqlDbType.VarChar, 100);
parameterName.Value = reg.Sex;
parameterAge.Value = reg.Age;
parameterSex.Value = reg.Email;
parameterAddress.Value = reg.Address;
parameterEmail.Value = reg.Email;
parameterPhone.Value = reg.Phone;
cmd.Parameters.Add(parameterName);
cmd.Parameters.Add(parameterAge);
cmd.Parameters.Add(parameterSex);
cmd.Parameters.Add(parameterAddress);
cmd.Parameters.Add(parameterEmail);
cmd.Parameters.Add(parameterPhone);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
}
}
catch (Exception ex)
{
throw ex;
}
}
