[英].net MVC and url.Action with marging anonymous
我嘗試給2個匿名對象添加邊距,並將結果傳遞給urlHelper.action()方法,但結果錯誤,
這是我的代碼:
public static MvcHtmlString EditButton(this HtmlHelper helper, object routeValues = null, string text = "")
{
UrlHelper u = new UrlHelper(helper.ViewContext.RequestContext);
routeValues = routeValues ?? new { };
string returnUrl = (string)helper.ViewBag.returnUrl;
if (false == string.IsNullOrEmpty(returnUrl))
routeValues = ButtonHelper.Merge(routeValues, new { returnUrl = returnUrl });
var x = u.RouteUrl(new RouteValueDictionary(routeValues));
string href = u.Action("Edit",new RouteValueDictionary(routeValues));//<--here I aspect that href=".../edit/123?returnUrl=...."
text = string.IsNullOrEmpty(text) ? Resources.Commons.Edit : text;
// < a href = '@Url.Action("Edit", new { id = Model.Id })' class="btn btn-default">
// <i class="glyphicon glyphicon-pencil"></i> @Resources.Commons.Edit
//</a>
MvcHtmlString r = new MvcHtmlString(String.Format("<a href=\"{0}\" class=\"btn btn-default\">"
+ "<i class=\"glyphicon glyphicon-pencil\"></i> {1}</a>", href, text));
return r;
}
public static dynamic Merge(dynamic item1, dynamic item2)
{
var result = new ExpandoObject();
var d = result as IDictionary<string, object>; //work with the Expando as a Dictionary
foreach (System.Reflection.PropertyInfo fi in item1.GetType().GetProperties())
{
d[fi.Name] = fi.GetValue(item1, null);
}
foreach (System.Reflection.PropertyInfo fi in item2.GetType().GetProperties())
{
d[fi.Name] = fi.GetValue(item2, null);
}
return d;
}
有什么問題,我將href變量表示為:“ ... / edit / 123?returnUrl = ....”
謝謝你的問候
好吧,我解決了,我修改Marge方法的新代碼是:
public static RouteValueDictionary Merge(dynamic item1, dynamic item2)
{
var result = new ExpandoObject();
var d = new RouteValueDictionary();
foreach (System.Reflection.PropertyInfo fi in item1.GetType().GetProperties())
{
d[fi.Name] = fi.GetValue(item1, null);
}
foreach (System.Reflection.PropertyInfo fi in item2.GetType().GetProperties())
{
d[fi.Name] = fi.GetValue(item2, null);
}
return d;
}
