构建用于重定向的查询字符串

Question

我是编程新手。我正在尝试构建一个查询字符串以重定向到另一个操作。

以下是我尝试重定向到

的操作

public ActionResult Rate(int Wid, int Uid)
{ 
}

以下是我尝试从

重定向的操作

public ActionResult ConfirmHire2(bool userConfirmed, int confirId)
{
    int Wid = cm.GetCleanerIdFromSale(confirId);
    int Uid = um.GetUserIdFromSale(confirId);
    //I need something to this affect but it is not working
    //return RedirectToAction("'Rate?Wid=' + Wid + 'Uid=' + Uid");
 }

Answer 1

查询字符串参数不是操作 name 的一部分，而是要添加到URL的值。 RedirectToAction有an overload，它接受​​这些参数的对象，框架将用它来构建URL：

return RedirectToAction("Rate", new { Wid = Wid, Uid = Uid });

Answer 2

试试这个：

return RedirectToAction("Rate", new { Wid = Wid, Uid = Uid });

Answer 3

您可以将id作为routeValues参数的一部分传递：

return RedirectToAction("Rate", new { Wid = 123, Uid = 123 });

Answer 4

public ActionResult ConfirmHire2 (bool userConfirmed, int confirId)
{
    int Wid = cm.GetCleanerIdFromSale(confirId);
    int Uid = um.GetUserIdFromSale(confirId);
    // Use C#6 `nameof` API for compile time validation of your `RedirectToAction` call
    return RedirectToAction(nameof(Rate), new { Wid = Wid, Uid = Uid });
}

public ActionResult Rate(int Wid, int Uid)
{ 
}
