asp.net-mvc - "return View()"和 "return PartialView()"有什么区别

Question

我知道部分 View 用于渲染 View 的一部分。但我不明白 return View() 和 return PartialView() 之间有什么区别以及什么时候使用它们。

Answer 1

返回View() - 渲染 .aspx|.cshtml 页面

• 呈现一个普通的 .aspx 页面，也可以包含部分 View

返回PartialView() - 渲染.ascx|.cshtml控件

• 向浏览器呈现一段 HTML，可通过 AJAX 或非 AJAX 请求进行请求。

View() 返回ViewResultPartialView() 返回 PartialViewResult两者都继承自 ViewResultBase

差异由 Reflector 描述下面...

public class PartialViewResult : ViewResultBase
{
   // Methods
   protected override ViewEngineResult FindView(ControllerContext context)
   {
      ViewEngineResult result = base.ViewEngineCollection.FindPartialView(context, base.ViewName);
      if (result.View != null)
      {
         return result;
      }
      StringBuilder builder = new StringBuilder();
      foreach (string str in result.SearchedLocations)
      {
         builder.AppendLine();
         builder.Append(str);
      }
      throw new InvalidOperationException(string.Format(CultureInfo.CurrentUICulture, MvcResources.Common_PartialViewNotFound, new object[] { base.ViewName, builder }));
   }
}


public class ViewResult : ViewResultBase
{
   // Fields
   private string _masterName;

   // Methods
   protected override ViewEngineResult FindView(ControllerContext context)
   {
      ViewEngineResult result = base.ViewEngineCollection.FindView(context, base.ViewName, this.MasterName);
      if (result.View != null)
      {
         return result;
      }
      StringBuilder builder = new StringBuilder();
      foreach (string str in result.SearchedLocations)
      {
         builder.AppendLine();
         builder.Append(str);
      }
      throw new InvalidOperationException(string.Format(CultureInfo.CurrentUICulture, MvcResources.Common_ViewNotFound, new object[] { base.ViewName, builder }));
   }

   // Properties
   public string MasterName
   {
      get
      {
         return (this._masterName ?? string.Empty);
      }
      set
      {
         this._masterName = value;
      }
   }
}
