如何对asp.net mvc4中的提交按钮执行特定操作

Question

我正在使用双列表框并使用两个按钮将数据从一个列表框移动到另一个列表框..

下面是我将数据从一个列表框移动到另一个列表框的代码

InstituteInformation.cs

    public class InstituteInformation
    {
public int Id { get; set; }

public string InstituteName { get; set; }
    }

MemberAccessRights.cs

    public class MemberAccessRights
    {
public int Id { get; set; }

public List<InstituteInformation> AvailableNames { get; set; }
public int[] AvailableSelected { get; set; }


public List<InstituteInformation> RequestedNames { get; set; }
public string[] RequestedSelected { get; set; }

public string SavedRequested { get; set; }
    }

//控制器

   //
    // GET: /MemberDetails/Create

     public ActionResult Create()
        {
Wrapper1 MD = new Wrapper1();
            MD.MAR = new MemberAccessRights{ AvailableNames = getAllInstituteNameList(), RequestedNames = new List<InstituteInformation>() };
return View(MD);
        }

//
// POST: /MemberDetails/Create

        [HttpPost]
    public ActionResult Create(Wrapper1 MD, string add, string remove)
        {
try
            {
ModelState.Clear();
RestoreSavedState(MD);
if (!string.IsNullOrEmpty(add))
AddNames(MD);
elseif (!string.IsNullOrEmpty(remove))
AddNames(MD);
SaveState(MD);

    using (varMDConext = new WrapperDB())
                {
MDConext.MBIDBS.Add(MD.MBI);
MDConext.MACDBS.Add(MD.MAC);
MDConext.MARDBS.Add(MD.MAR);
MDConext.MODBS.Add(MD.MO);
                }

returnRedirectToAction("Index");
            }
catch
            {
return View(MD);
            }
        }
        #regionSupportFuncs

void SaveState(Wrapper1 MD)
        {
MD.MAR.SavedRequested = string.Join(",", MD.MAR.RequestedNames.Select(p =>p.Id.ToString()).ToArray());

////Available Names = All - Requested
MD.MAR.AvailableNames = getAllInstituteNameList().Except(MD.MAR.RequestedNames).ToList();

        }

//RestoreSavedState
void RestoreSavedState(Wrapper1 MD)
        {
MD.MAR.RequestedNames = newList<InstituteInformation>();

if (!string.IsNullOrEmpty(MD.MAR.SavedRequested))
            {
string[] nameids = MD.MAR.SavedRequested.Split(',');
var name = getAllInstituteNameList().Where(p =>nameids.Contains(p.Id.ToString()));
MD.MAR.RequestedNames.AddRange(name);
            }
        }

//AddNames
void AddNames(Wrapper1 MD)
        {
if (MD.MAR.AvailableSelected != null)
            {
var names = getAllInstituteNameList().Where(p =>MD.MAR.AvailableSelected.Contains(p.Id));
MD.MAR.RequestedNames.AddRange(names);
MD.MAR.AvailableSelected = null;
            }
        }

//RemoveNames
void RemoveNames(Wrapper1 MD)
        {
if (MD.MAR.RequestedSelected != null)
            {
MD.MAR.RequestedNames.RemoveAll(p =>MD.MAR.RequestedSelected.Contains(p.Id.ToString()));
MD.MAR.RequestedSelected = null;
            }
        }
        #endregion

查看

List of Financial Institute

     <%:Html.ListBoxFor(model=>model.MAR.AvailableSelected,new MultiSelectList(Model.MAR.AvailableNames,"Id","InstituteName",Model.MAR.AvailableSelected)) %>

     <div>

     <input id="add" name="add" type="submit" value=">>" />
     <br />
     <input id="remove" name="remove" type="submit" value="<<" />

     </div>


    <%:Html.ListBoxFor(m=>m.MAR.RequestedSelected,new MultiSelectList(Model.MAR.RequestedNames,"Id","Name",Model.MAR.RequestedSelected)) %>

但问题是当我点击添加（>>）或删除（>)或remove(

请帮忙解决这个问题

这个想法是一个表单可以包含多个提交按钮，以不同的方式发布表单。
