Question

我有一个看起来像这样的注册表： signup.aspx.cs -

protected void submit_Click(object sender, EventArgs e)
{
    string name = Request.Form["name"];
    string email = Request.Form["email"];
    string password = Request.Form["password"];
    string fileName = "Database.mdf";
    string sql = "INSERT INTO UserInfo VALUES('" + name + "','" + email + "','" + password + "')";
    MyAdoHelper.DoQuery(fileName,sql);
}

myAdoHelper.DoQuery -

 public static void DoQuery(string fileName, string sql)
{

    SqlConnection conn = ConnectToDb(fileName);
    conn.Open();
    SqlCommand com = new SqlCommand(sql, conn);
    com.ExecuteNonQuery();
    com.Dispose();
    conn.Close();

}

MyAdoHelper.ConnectToDb

public static SqlConnection ConnectToDb(string fileName)
{
    string path = HttpContext.Current.Server.MapPath("App_Data/");
    path += fileName;
    //string path = HttpContext.Current.Server.MapPath("App_Data/" + fileName);
    string connString = @"Data Source = (LocalDB)\MSSQLLocalDB; AttachDbFilename = C:\Users\User\Documents\Visual Studio 2015\WebSites\WebSite6\App_Data\Database.mdf; Integrated Security = True";
    SqlConnection conn = new SqlConnection(connString);
    return conn;

}

这是我的表 -

CREATE TABLE [dbo].[UserInfo] (
[Name]     NVARCHAR (50) NOT NULL,
[Email]    NVARCHAR (50) NOT NULL,
[Password] NVARCHAR (50) NOT NULL

）;

点击注册后，它看起来已经提交但是当我转到表格数据时，它只在表格中创建一个没有数据的新行这是2个寄存器后的表 Table

signup.aspx -

          <table>
              <tr>

             </tr>
              <tr>
                  <td><asp:TextBox ID="password" TextMode="Password" placeholder="Password" name="password" required="required" runat="server"></asp:TextBox></td>

              </tr>
              <tr>
                  <td><asp:TextBox ID="repassword" TextMode="Password" placeholder="Repeat Password" name="repassword" required="required" runat="server"></asp:TextBox></td>

              </tr>
          </table>     
            <br />
            <asp:Button ID="submit" runat="server" Text="Submit" OnClick="submit_Click" />
            <input type="reset" value="Reset" />

           </div>

提交后，数据不会插入表中
