我想在页面上显示产品列表。但在显示价格时，它显示的是十进制值，如15.00，但我只想显示15。 这是我的listofproducts.cshtml文件
@model PagedList.IPagedList<Shoppers.Context.Product>
@using PagedList.Mvc;
@if (@Session["Name"] != null)
{
if (@Session["Name"].Equals("shopper.admin@yopmail.com"))

ViewBag.Title = "ListOfProducts";
Layout = "~/Views/Shared/_Layout1.cshtml";

我只想以整数格式显示价格。请帮帮我。
答案 0 :(得分：2)
MVC提供了许多设置字段格式的方法。至少有一个选项是使用指定0小数位数的格式在Price属性上设置DisplayFormat属性。
您可以使用与String.Format或Decimal.ToString相同的标准或自定义格式字符串。例如，N0将小数格式化为带0位数的数字：
[DisplayFormat(DataFormatString = "{0:N0}", ApplyFormatInEditMode = true)]
[Required(ErrorMessage = "Price is required")]
[RegularExpression("^[0-9]*$", ErrorMessage = "Price must be numeric")]
public decimal Price { get; set; }
此属性仅适用于DisplayFor和EditFor方法。

与How do I format to only include decimal if there are any
类似只需在razor视图中添加字符串格式即可。 我希望它应该对你有所帮助。
@Html.TextBoxFor(m => m.Price,Model.Price.ToString("G29"))
