我刚刚开始使用 C# 进行 Web 开发，所以我还很新。我正在尝试做一个基本的“注册新用户代码”我正在引用我保存在 SQL Server 中的存储过程，一切似乎都很好。但是由于我对 Web 开发非常陌生，所以我不确定我是否遗漏了一些东西。问题是数据库不会更新。我运行应用程序并输入信息，单击按钮后，我刷新数据库，但它没有插入。很确定存储过程工作正常......查询测试有效。
C＃：
namespace WebApplication2.Account
{
public partial class Register : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void OnClick(object sender, EventArgs e)
{
String connstr = ConfigurationManager.ConnectionStrings["PracticeConnectionString"].ConnectionString;
SqlConnection conn = new SqlConnection(connstr);
SqlCommand cmd = new SqlCommand("InsertUser", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@UserName", SqlDbType.VarChar).Value = UserName.Text;
cmd.Parameters.Add("@Email", SqlDbType.VarChar).Value = Email.Text;
cmd.Parameters.Add("@Password", SqlDbType.VarChar).Value = Password.Text;
try
{
conn.Open();
cmd.ExecuteNonQuery();
Response.Redirect("About.aspx");
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
conn.Close();
}
}
}
}
