我有一个Web API方法,需要两个双参数:

存储库界面:

public interface IInventoryItemRepository
{
. . .
    IEnumerable<InventoryItem> GetDepartmentRange(double deptBegin, double deptEnd);
. . .
}

库:

public IEnumerable<InventoryItem> GetDepartmentRange(double deptBegin, double deptEnd)
{
    // Break the doubles into their component parts:
    int deptStartWhole = (int)Math.Truncate(deptBegin);
    int startFraction = (int)((deptBegin - deptStartWhole) * 100);
    int deptEndWhole = (int)Math.Truncate(deptEnd);
    int endFraction = (int)((deptBegin - deptEndWhole) * 100);

    return inventoryItems.Where(d => d.dept >= deptStartWhole).Where(e => e.subdept >= startFraction)
        .Where(f => f.dept <= deptEndWhole).Where(g => g.subdept >= endFraction);
}
