C#在匿名类型的foreach循环中拆分逗号分隔的字符串

Question

我正在尝试将产品的标题从 Nitric Acid 70% , ACS REAGENT GRADE, 2.5 Liter(7 Lbs) Bottle 拆分为 Nitric Acid 70%。在我的代码中，我首先加入了两个以客户名称为键的集合。然后我对类传播列表进行了 foreach 循环，并添加了来自客户和产品的成员。但是，在 Title = record.Title, 中，我不希望完整的标题名称只是第一个逗号之前的第一个字符串。我怎样才能做到这一点？我试图使用 .split，但我认为我没有正确理解它

private static IEnumerable<SpreadList> Combine(IEnumerable<Address> addresses, IEnumerable<Address> products)
{

    var customersandproducts = addresses.Select(x => new { x.Name, x.AddressLine1, x.AddressLine2, x.City, x.State, x.S_OrderId, x.PostalCode })
                                    .Join(products, custs => custs.S_OrderId, prod => prod.P_OrderId,
                                        (custs, prod) => new { custs.Name, prod.Title, prod.ShippingPrice, prod.ItemPrice, prod.Quantity });

    var records = new List<SpreadList>();

    foreach (var record in customersandproducts)
    {
        records.Add(new SpreadList()
        {
            Name = WebUtility.HtmlDecode(record.Name),
            Title = record.Title,
            ItemPrice = record.ItemPrice,
            ShippingPrice = record.ShippingPrice,
            Quantity = record.Quantity,
        });

    }
    return records;
}

public class SpreadList
{
    public string Name { get; set; }
    public string Title { get; set; }
    public string ShippingPrice { get; set; }
    public string ItemPrice { get; set; }
    public string Quantity { get; set; }
}

Answer 1

未经测试，但在您的 records.Add(new SpreadLIst()) 代码块中，我建议:

Title = record.Title.Substring(0,record.Title.IndexOf(',')-1),

另一种选择是:

Title = record.Title.Split(',')[0]
