如何让NuGet安装/更新packages.config中的所有软件包？(How do I get NuGet to install/update all the packages in the packages.config?)

 这对我有用。 
 
SortSpan sortSpan = SortSpan.All;                               
Type type = typeof(SortSpan);
MemberInfo[] memberInfo = type.GetMember(sortSpan.ToString());
object[] attributes = memberInfo[0].GetCustomAttributes(typeof(DisplayAttribute), false);
string name = ((DisplayAttribute)attributes[0]).Name;
 
 我使用了此链接中的答案获取Enum值的属性 
 
 [更新]这是合并的代码。 它没有经过测试，仅使用文本编辑器进行了编辑。 
 
 @*Top Sort Span Buttons *@
    @if(Model.Context != null && Model.Sort == TestSite.Domain.Models.SortAlgorithm.Top)
    {
        < div >
            < ul class="tabmenu submenu">
                @{
                    var spans = new SortSpan[] { SortSpan.Day, SortSpan.Week, SortSpan.Month, SortSpan.Quarter, SortSpan.Year, SortSpan.All };
                    Type type = typeof(SortSpan);
                    foreach (var span in spans)
                    {
                        MemberInfo[] memberInfo = type.GetMember(span.ToString());
                        object[] attributes = memberInfo[0].GetCustomAttributes(typeof(DisplayAttribute), false);
                        string name = ((DisplayAttribute)attributes[0]).Name;
                        <li class='@(Model.Span.HasValue && Model.Span.Value == span ? "selected" : "disabled")'>@Html.RouteLink(name, Model.Submissions.RouteName, new { sort = (Model.Sort == null ? "" : Model.Sort.ToString().ToLower()), span = name.ToLower() })</li>
                    }
                }
            </ul>
        </div>
    }

This works for me. 
 
SortSpan sortSpan = SortSpan.All;                               
Type type = typeof(SortSpan);
MemberInfo[] memberInfo = type.GetMember(sortSpan.ToString());
object[] attributes = memberInfo[0].GetCustomAttributes(typeof(DisplayAttribute), false);
string name = ((DisplayAttribute)attributes[0]).Name;
 
I used an answer from this link Getting attributes of Enum's value
 
[Update] Here is the merged code. It's not tested, just edited with an text editor.

                        object[] attributes = memberInfo[0].GetCustomAttributes(typeof(DisplayAttribute), false);
                        string name = ((DisplayAttribute)attributes[0]).Name;

                    }
                }
            </ul>
        </div>
    }
