Question

如果在我的视图中有条件，我该如何添加？

@if(Model.Remaining > 0 && Model.Total >= 1)
{
/* do something */
}
@if(Model.Remaining > 0 || Model.Total >= 1 || Model.AmountPaid > 100)
{
/* do something */
}

在if块中放置某种HTML控件，并确保模型上定义的属性值具有将导致if块内的代码呈现的值。

<强>型号：

public class ModelData
{
    public int Remaining { get; set; }
    public int Total { get; set; }
    public decimal AmountPaid { get; set; }
}

<强>控制器：

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var model = new ModelData { Remaining = 1, Total = 1, AmountPaid = 99 };
        return View(model);
    }
}

查看：

@model MVCTutorial.Models.ModelData @{ Layout = null; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Home</title> </head> <body> @if (Model.Remaining > 0 && Model.Total >= 1) { <h1>First if...</h1> } @if (Model.Remaining > 0 || Model.Total >= 1 || Model.AmountPaid > 100) { <h1>Second if...</h1> } </body> </html>

如何在MVC视图中使用IF（AND OR）条件？
