asp.net-mvc-3 - 当我使用动态查询时出现 500 错误

Question

我想现在我知道问题出在哪里，但我不知道我会解决这个问题。

实际上我正在通过 entityFramework 4.1 获取数据，并且由于我的搜索条件是动态的，所以我只有一种方法可以做到这一点，enter code here这就是现在

using System;
using System.Linq;
using System.Data.Entity;
using QTrac.Models;
using System.Transactions;


namespace QTrac.DAL
{
    public class AssetManagementSearchRepository : RepositoryBase<AssetManagementSearch>, IAssetManagementSearchRepository
    {
        public AssetManagementSearchRepository(IUnitOfWork unitOfWork) : base(unitOfWork) { }

        #region IAssetManagementSearchResponseRepository Members

        public IQueryable<AssetManagementSearch> GetSearchResult(SearchRequest request)
        {
            IQueryable<AssetManagementSearch> query = DbSet;

            using (var context = new QTracContext()) {

                using (var tx = new TransactionScope(TransactionScopeOption.Required, new TransactionOptions() { IsolationLevel = IsolationLevel.ReadUncommitted })) {

                    //try {

                    if (!String.IsNullOrEmpty(request.FileCode)) {
                        query = query.Where(d => d.FileCode.StartsWith(request.FileCode));
                    }

                    if (!String.IsNullOrEmpty(request.SerialNo)) {
                        query = query.Where(d => d.SerialNo.StartsWith(request.SerialNo));
                    }

                    if (!String.IsNullOrEmpty(request.TopLevelEquipment)) {
                        query = query.Where(d => d.ParentToolSet.StartsWith(request.TopLevelEquipment));
                    }

                    if (!String.IsNullOrEmpty(request.EquipmentState)) {
                        query = query.Where(d => d.EqpState.StartsWith(request.EquipmentState));
                    }

                    if (!String.IsNullOrEmpty(request.EquipmentStatus)) {
                        query = query.Where(d => d.EqpStatus.StartsWith(request.EquipmentStatus));
                    }

                    if (!String.IsNullOrEmpty(request.DFP)) {
                        query = query.Where(d => d.DFP.StartsWith(request.DFP));
                    }

                    if (request.Active.HasValue) {
                        query = query.Where(d => d.IsActive == request.Active);
                    }

                    if (!String.IsNullOrEmpty(request.OwnerSite)) {
                        query = query.Where(d => d.OwnerSite.StartsWith(request.OwnerSite));
                    }

                    if (!String.IsNullOrEmpty(request.ControlSite)) {
                        query = query.Where(d => d.ControlSite.StartsWith(request.ControlSite));
                    }

                    if (!String.IsNullOrEmpty(request.Location)) {
                        query = query.Where(d => d.Location.StartsWith(request.Location));
                    }

                    if (!String.IsNullOrEmpty(request.StampedFC)) {
                        query = query.Where(d => d.STAMPEDFC.StartsWith(request.StampedFC));
                    }

                    if (!String.IsNullOrEmpty(request.StampedSN)) {
                        query = query.Where(d => d.STAMPEDSN.StartsWith(request.StampedSN));
                    }

                    if (!String.IsNullOrEmpty(request.CustomsStatus)) {
                        query = query.Where(d => d.CustomsStatus.StartsWith(request.CustomsStatus));
                    }

                    if (!String.IsNullOrEmpty(request.ImportType)) {
                        query = query.Where(d => d.ImportType.StartsWith(request.ImportType));
                    }

                    if (!String.IsNullOrEmpty(request.ClientBasket)) {
                        query = query.Where(d => request.ClientBasket.Contains(d.ClientBasket));
                    }

                    if (!String.IsNullOrEmpty(request.ImportClient)) {
                        query = query.Where(d => request.ImportClient.Contains(d.ImportClient));
                    }

                    if (!String.IsNullOrEmpty(request.AssignedClient)) {
                        query = query.Where(d => d.AssignedClient.StartsWith(request.AssignedClient));
                    }

                    if (!String.IsNullOrEmpty(request.FileCodesByToolFamily)) {
                        query = query.Where(d => request.FileCodesByToolFamily.Contains(d.FileCode));
                    }

                    return query.AsNoTracking();

                    //}
                    //catch(Exception e) {
                    //    throw e.InnerException;
                    //}
                    //finally {

                    //   //Context.Dispose();
                    //}


                }

            }

        }

        #endregion


    }
}

通常它工作正常，一种情况是当我从源代码管理下载我的代码时它不起作用，第二种情况是昨天我正在使用相同的解决方案但不同的页面我在 .edmx 文件中添加了许多视图和存储过程，当我测试这个搜索屏幕时它不起作用，每次都返回 500 错误，我从 mvc telerik 网格错误事件中捕获了 500 错误。

如果我将此代码更改为没有动态

return Get(filter: p => p.ACTIVE == active, orderBy: o => o.OrderBy(p => p.NAME), tracking: false);

然后搜索开始工作。

请告诉我这个问题。谢谢
