如何在ASP.NET MVC中实现报表打印和导出

Posted 2023-03-25

参考技术A public ActionResult UsingViewData()



ViewData["Title"] = " Using ViewData";

ViewData["ProjectName"] = "My Test Project";

ViewData["ProjectDescription"] = "This is Test Project to demo Viewdata and viewbag details";

ViewData["StartDate"] = new DateTime(2011, 1, 1);

ViewData["TotalPrice"] = 1000;

ViewData["TotalDays"] = 100;

Dictionary<string, string> stackholder = new Dictionary<string, string>();

stackholder.Add("Client","Mr. Client");

stackholder.Add("Manager","Mr. Joy");

stackholder.Add("Team Leader","Mr.Toy");

stackholder.Add("Sr. developer", "Mr.dojoy");

stackholder.Add("developer", "Mr. nodoy");

ViewData["stackholder"] = stackholder;

List<string> modules = new List<string>();

modules.Add("Admin module");

modules.Add("ShoppingCart module");

modules.Add("CMS module");

ViewData["modules"] = modules;

return View();

如何使用trackerenableddbcontext在asp.net mvc5和代码中的实体框架中实现审计跟踪

【中文标题】如何使用trackerenableddbcontext在asp.net mvc5和代码中的实体框架中实现审计跟踪

【英文标题】：How to implement audit trail in asp.net mvc5 and entity-framework in code first, using trackerenableddbcontext

【发布时间】：2019-12-02 12:47:03

【问题描述】：

我正在使用实体框架和代码优先迁移开发 MVC5 应用程序，我想实施审计跟踪。我发现了一个名为 trackerenableddbcontext 的 NuGet 包，看起来很容易使用。但是，我确实安装了该软件包，并执行了以下代码，但仍然没有将任何内容添加到审计表中。

我已经实现了继承自Tracker Context，如代码所示

DBContext class
public class SIContext : TrackerContext //DbContext

    public SIContext()
        : base("name=SIConnectionString")
    
    


    public virtual DbSet<Role> Roles  get; set; 
    public virtual DbSet<User> Users  get; set; 
    public virtual DbSet<Menu> Menus  get; set; 
    public virtual DbSet<MenuPermission> MenuPermissions  get; set; 
    public virtual DbSet<ProductCategory> ProductCategorys  get; set; 
    public virtual DbSet<Product> Products  get; set; 
    public virtual DbSet<Tax> Taxs  get; set;

    //
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    

        modelBuilder.Configurations.Add(new ShopMate.Maping.RoleMap());

我要跟踪的表

[TrackChanges]
public class Product

    [DisplayName("S.No")] 
    public int Id  get; set; 
    [Required]
    [StringLength(100)] 
    [DisplayName("Name")] 
    public string Name  get; set; 
    [Required]
    [DisplayName("Product Category")] 
    public int? ProductCategoryId  get; set; 
    public virtual ProductCategory ProductCategory_ProductCategoryId  get; set; 
    [StringLength(100)] 
    [DisplayName("Bar Code")] 
    public string BarCode  get; set; 
    [Required]
    [DisplayName("Purchase Price")] 
    public Decimal PurchasePrice  get; set;

    [Required]
    [DisplayName("Warehouse")] 
    public int WarehouseId  get; set; 

    [DisplayName("Discount")]
    public Nullable<Decimal> Discount  get; set; 

    [DisplayName("Remaining Quantity")]
    public Nullable<Decimal> RemainingQuantity  get; set; 

    [DisplayName("Remaining Amount")]
    public Nullable<Decimal> RemainingAmount  get; set; 

    [StringLength(100)]
    [DisplayName("HSN")]
    public string HSN  get; set; 

    public virtual ICollection<ProductStock> ProductStock_ProductIds  get; set; 
    public virtual ICollection<Sale> Sale_ProductIds  get; set; 
    public virtual ICollection<InvoiceItems> InvoiceItems_ProductIds  get; set; 
    public virtual ICollection<Purchase> Purchase_ProductIds  get; set; 

控制器功能

[HttpPost]
   [ValidateAntiForgeryToken]
   [ValidateInput(false)]
    public ActionResult Edit(Product ObjProduct, HttpPostedFileBase ProductImage, string HideImage1)
    
        System.Text.StringBuilder sb = new System.Text.StringBuilder();
        int userId = Convert.ToInt32(Env.GetUserInfo("userid"));
        try
        

            if (ModelState.IsValid)
            
                if (ProductImage != null)
                
                    var fileName = MicrosoftHelper.MSHelper.StarkFileUploaderCSharp(ProductImage, Server.MapPath("~/Uploads"));
                    ModelState.Clear();
                    ObjProduct.ProductImage = fileName;
                
                else
                
                    ObjProduct.ProductImage = HideImage1;
                


                db.Entry(ObjProduct).State = EntityState.Modified;

                db.SaveChanges(userId);

                sb.Append("Sumitted");
                return Content(sb.ToString());
            
            else
            
                foreach (var key in this.ViewData.ModelState.Keys)
                
                    foreach (var err in this.ViewData.ModelState[key].Errors)
                    
                        sb.Append(err.ErrorMessage + "<br/>");
                    
                
            
        
        catch (Exception ex)
        
            sb.Append("Error :" + ex.Message);
        


        return Content(sb.ToString());

    

我希望它将更改保存到数据库、audidlog 和 auditlogdetails 表中。

【参考方案1】：

当您使用附加实体到 DBContext 时，您需要在应用程序启动时添加 GlobalTrackingConfig.DisconnectedContext = true;。
