Asp.net当插入数据库没有发生任何插入

Question

数据这是我UserRegister.cs车型

public class UserRegister 
    { 
     public int Id { get; set; } 
     [Required(ErrorMessage = "Please provide username", AllowEmptyStrings = false)] 
     public string Username { get; set; } 
     [Required(ErrorMessage = "Please provide Password", AllowEmptyStrings = false)] 
     [DataType(System.ComponentModel.DataAnnotations.DataType.Password)] 
     [StringLength(50, MinimumLength = 8, ErrorMessage = "Password must be 8 char long.")] 
     public string Password { get; set; } 
     [Compare("Password", ErrorMessage = "Confirm password dose not match.")] 
     [DataType(System.ComponentModel.DataAnnotations.DataType.Password)] 
     public string ConfirmPassword { get; set; } 
     [Required(ErrorMessage = "Please provide full name", AllowEmptyStrings = false)] 
     public string FullName { get; set; } 

     [RegularExpression(@"^([0-9a-zA-Z]([\+\-_\.][0-9a-zA-Z]+)*)+@(([0-9a-zA-Z][-\w]*[0-9a-zA-Z]*\.)+[a-zA-Z0-9]{2,3})$", 
      ErrorMessage = "Please provide valid email id")] 
     public string Email { get; set; } 
    } 

这是我Customercontroller，我执行要插入数据库到它的功能。

public ActionResult Customer() 
     { 
      return View(new UserRegister()); 
     } 

     [HttpPost] 
     public ActionResult Customer(UserRegister model1) 
     { 
      if (ModelState.IsValid) 
      { 
       SqlConnection cnn; 
       string connectionString = ConfigurationManager.ConnectionStrings 
              ["DefaultConnection"].ConnectionString; 
       cnn = new SqlConnection(connectionString); 
       try 
      { 
       cnn.Open(); 
       Response.Write("Connection Made"); 




       string query = "INSERT INTO Customer(Username,Password,Email) VALUES('" + model1.Username + "','" + model1.Password + "','" + model1.Email + "')"; 
       SqlCommand command = new SqlCommand(query, cnn); 
       command.ExecuteNonQuery(); 

      } 

      catch 
      { 
       Response.Write("error"); 

      } 

      finally 
      { 
       cnn.Close(); 

      } 

       Response.Write("Insert succesful"); 

       ViewBag.Message = "Customer Page"; 
      } 
       return View(model1); 

     } 

的事情是，当我插入到数据库中没有发生，则不插入数据。我想问问是否有一些我需要添加到我的useregister.cs模型中，因为我阅读了一些指导我关于实体框架的信息，需要添加一些数据类型的东西。因为我更加迷惑，因为我对asp.net很陌生。真的希望你们能帮助我。

HTML代码

@model DDAC_Assignment_jason.Models.UserRegister 

@{ 
    ViewBag.Title = "Customer"; 
} 

<h2>Customer</h2> 

@using (Html.BeginForm()) 
{ 
    @Html.ValidationSummary(true) 
    <fieldset> 
     <legend>User</legend> 
     @Html.AntiForgeryToken() 
     @if (ViewBag.Message != null) 
     { 
      <div style="border:solid 1px green"> 
       @ViewBag.Message 
      </div> 
     } 


     <div class="editor-label"> 
      @Html.LabelFor(model => model.Email) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.Email) 
      @Html.ValidationMessageFor(model => model.Email) 
     </div> 
     <div class="editor-label"> 
      @Html.LabelFor(model => model.Username) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.Username) 
      @Html.ValidationMessageFor(model => model.Username) 
     </div> 

     <div class="editor-label"> 
      @Html.LabelFor(model => model.Password) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.Password) 
      @Html.ValidationMessageFor(model => model.Password) 
     </div> 

     <div class="editor-label"> 
      @Html.LabelFor(model => model.ConfirmPassword) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.ConfirmPassword) 
      @Html.ValidationMessageFor(model => model.ConfirmPassword) 
     </div> 
     <p> 
      <input type="submit" value="Create" /> 
     </p> 
    </fieldset> 
} 

<div> 
    @Html.ActionLink("Back to List", "Index") 
</div>

你可以写try catch块，并把一个破发点中的渔获物。

try 
{ 
    cnn.Open(); 
    Response.Write("Connection Made"); 

    string query = "INSERT INTO Customer(Username,Password,Email) VALUES('" + model1.Username + "','" + model1.Password + "','" + model1.Email + "')"; 
    SqlCommand command = new SqlCommand(query, cnn); 
    command.ExecuteNonQuery(); 
} 
catch 
{ //break point 
    //log 
} 
finally 
{ 
    cnn.Close(); 
} 

，并将HTML会，

@using (Html.BeginForm("ActionName","ControllerName", FormMethod.Post))
