我在mvc中使用RedirectToAction方法时遇到问题.我的地图路线看起来像这样.
routes.MapRoute(
"Project",// Route name
"{Controller}/{Action}/{projectId}/{machineName}/{companyId}",new { controller = "Project",action = "Directives",projectId = 0,machineName = "",companyId = 0 } // Parameter defaults);
回报看起来像这样：
return RedirectToAction("Directives","Project",new { projectId = projectId,machineName = project.MachineName,CompanyId = user.Company_Id });
它工作正常,但我使用RedirectToAction它仍然看起来像这样
http://localhost:1843/Project/Directives?projectId=48&machineName=Netduino&companyId=27
控制器：
[HttpPost]
[ValidateInput(false)]
public ActionResult Create(Project project,string text)
{
ViewBag.MachineType = new List<string>(new string[] { "Machine Type A","Machine Type B","Machine Type C","Machine Type D","Machine Type E" });
if (ModelState.IsValid)
{
UserAccess user = (UserAccess)(Session["UserAccessInfo"]);
Int64 projectId = DataBase.DBProject.InsertProject(project.ProjectNumber,project.MachineName,project.MachineNameEnglish,1,project.Serial,text,user.Company_Id,project.MachineType);
return RedirectToAction ("Directives",new { projectId = 48,machineName = "Netduino",companyId = 27 });
// return RedirectToAction("Directives",CompanyId = user.Company_Id });
}
else
{
ModelState.AddModelError("","Invalid username or password");
}
return View();
}
接收控制器：
public ActionResult Directives(int projectId,string machineName,int companyId)
{
convertedDirectives = new List<Models.Directives>();
ViewBag.MachineName = machineName;
ViewBag.ProjectId = projectId;
List<object> Directives = new List<object>();
if (ModelState.IsValid)
{
Directives = DataBase.DBProject.GetDirectives(companyId);
foreach (List<object> dir in Directives)
{
Directives newDirective = new Models.Directives();
newDirective.CompanyID = Convert.ToInt32(dir[0]);
newDirective.DirectiveId = Convert.ToInt32(dir[1]);
newDirective.Id = Convert.ToInt32(dir[2]);
newDirective.DirectiveName = Convert.ToString(dir[3]);
newDirective.DirectiveNameShort = Convert.ToString(dir[4]);
newDirective.Created = Convert.ToDateTime(dir[5]);
convertedDirectives.Add(newDirective);
}
}
else
{
ModelState.AddModelError("","An error has ");
}
ViewBag.DirectivesList = convertedDirectives;
return View();
}
但我想要的方式是这样的.
http://localhost:1843/Project/Directives/48/Netduino/27
但奇怪的是,我可以手动输入Url并且它可以完美运行.我做错了什么？
解决方法
我有一些提示.
首先,不要命名您的路线.将null传递给第一个参数.有几个RedirectToRoute重载采用路由名称,RedirectToAction返回RedirectToRouteResult.
其次,不要给出所需参数的默认值.如果要使用默认值,请仅将默认值设置为最后一个参数.
routes.MapRoute(null,// don't name the route
"{controller}/{action}/{projectId}/{machineName}/{companyId}",new
{
controller = "Project",//projectId = 0,//machineName = "",//companyId = 0,}
);
第三,如有疑问,请尝试返回RedirectToRoute.传递控制器,动作和区域(如果适用)以及其他参数：
return RedirectToRoute(new
{
controller = "Project",// area = "SomeAreaName",// if the action is in an area
projectId = projectId,companyId = user.Company_Id,});
最后一个提示是使用T4MVC摆脱那些神奇的字符串.
routes.MapRoute(null,new
{
controller = MVC.Project.Name,action = MVC.Project.ActionNames.Directives,}
);
您可以在RedirectToRoute中使用相同的强类型,也可以使用T4MVC部分返回操作：
return RedirectToAction(MVC.Project.Directives
(projectId,user.Company_Id));
