2、添加服务端必须的组件：
A:Install-Package datatables.mvc5
B:Install-Package System.Linq.Dynamic
| 48 |
public
ActionResult Get([ModelBinder(
typeof
(DataTablesBinder))] IDataTablesRequest requestModel)
{
IQueryable<Asset> query = dbContext.Assets;
var
totalcount = query.Count();
#region Filtering
if
(requestModel.Search.Value!=
string
.Empty)
{
value = requestModel.Search.Value.Trim();
query = query.Where(p => p.Barcode.Contains(value) ||
p.Manufacturer.Contains(value) ||
p.ModelNumber.Contains(value) ||
p.Building.Contains(value)
);
}
filteredCount = query.Count();
#endregion
#region Sorting
sortedColumns = requestModel.Columns.GetSortedColumns();
orderByString =
.Empty;
foreach
(
column
in
sortedColumns)
{
orderByString += orderByString !=
.Empty ?
","
:
""
;
orderByString += (column.Data) + (column.sortDirection == Column.OrderDirection.Ascendant?
" asc"
:
" desc"
);
}
query = query.OrderBy(orderByString ==
" Barcode asc"
: orderByString);
#endregion
//Paging
query = query.Skip(requestModel.Start).Take(requestModel.Length);
data = query.Select(asset=>
new
{
AssetID=asset.AssetID,
Barcode=asset.Barcode,238);">Manufacturer=asset.Manufacturer,238);">ModelNumber=asset.ModelNumber,238);">Building=asset.Building,238);">RoomNo=asset.RoomNo,238);">Quantity=asset.Quantity
}).ToList();
return
Json(
new
DataTablesResponse(requestModel.Draw,data,filteredCount,totalcount),JsonRequestBehavior.AllowGet);
}

4、运行程序，查看结果
