asp.net的MVC插入似乎并不为我

Question

我的控制器调用库插入方法中的所有值都通过，但它不会插在我的表...

我控制器的方法，

[AcceptVerbs(HttpVerbs.Post)] 
     public ActionResult Create([Bind(Exclude = "Id")]FormCollection collection) 
     { 
      try 
      { 
       MaterialsObj materialsObj = new MaterialsObj(); 
       materialsObj.Mat_Name = collection["Mat_Name"]; 
       materialsObj.Mes_Id = Convert.ToInt64(collection["MeasurementType"]); 
       materialsObj.Mes_Name = collection["Mat_Type"]; 
       materialsObj.CreatedDate = System.DateTime.Now; 
       materialsObj.CreatedBy = Convert.ToInt64(1); 
       materialsObj.IsDeleted = Convert.ToInt64(1); 
       consRepository.createMaterials(materialsObj); 

       return RedirectToAction("Index"); 
      } 
      catch 
      { 
       return View(); 
      } 
     } 

工作

和我的仓库，

public MaterialsObj createMaterials(MaterialsObj materialsObj) 
{ 
    Material mat = new Material(); 
    mat.Mat_Name = materialsObj.Mat_Name; 
    mat.Mat_Type = materialsObj.Mes_Name; 
    mat.MeasurementTypeId = materialsObj.Mes_Id; 
    mat.Created_Date = materialsObj.CreatedDate; 
    mat.Created_By = materialsObj.CreatedBy; 
    mat.Is_Deleted = materialsObj.IsDeleted; 
    db.Materials.InsertOnSubmit(mat); 
    return materialsObj; 
} 

我在这里缺少什么任何建议....

Answer 1

据我所见，你错过了一个db.SubmitChanges();保存到数据库。

Answer 2

db.Materials.InsertOnSubmit(mat); 
db.SubmitChanges(); // <--------------- 
return materialsObj; 

Answer 3

您是不是错过了致电SubmitChanges？

db.Materials.InsertOnSubmit(mat); 
db.SubmitChanges();
