如果我有一个数字列表:

1,2,3,4,5,6,7,8

我想按特定的数字订购,然后展示其余部分.例如,如果我选择'3',列表应该是:

3,1,2,4,5,6,7,8

寻找linq和c#.谢谢

我正在尝试使用第三方Web服务 https://staging.identitymanagement.lexisnexis.com/identity-proofing/services/identityProofingServiceWS/v2?wsdl

我已将其添加为服务引用,但我不确定如何传递标头的凭据.

如何使标头请求与此格式匹配？

我有一个类别表:

 Catid | Desciption
 1 | Color
 2 | Size
 3 | Material

和一个类别项目表

 Catid | Name
 1 | Red
 1 | Blue
 1 | Green
 2 | Small
 2 | Med
 2 l Large
 3 | Cotton
 3 | Silk

我需要遍历所有项目并将其显示在这样的标签中:

 Red Small Cotton
 Red Small Silk
 Red Med Cotton
 Red Med Silk
 Red Large Cotton
 Red Large Silk
 Blue Small Cotton
 Blue Small Silk
 Blue Med Cotton
 Blue Med Silk
 Blue Large Cotton
 Blue Large Silk
 Green Small …

在所选主要类别的所有子类别中获取所有产品的最佳方法是什么？试图在大约80个子类别中获得10000个产品,但这种方法太慢了.有什么建议？使用c#和Linq来SQL

//list for the child categories
private List<int> catsChildList = new List<int>();

GetChildCats(123);

//get all the child categories of main category '123'

private void GetChildCats(int _parentCat)
{
    var cats = (from c in db2.tbl_cart_categories
                where c.ParentID == _parentCat
                select new { c.CategoryID });
    if (cats.Count() > 0)
    {
        foreach (var cat in cats)
        {
            int _cat = Convert.ToInt32(cat.CategoryID);
            catsChildList.Add(_cat);
            GetChildCats(_cat);
        }
    }
}

//Get the products
var products = (from p in db2.products_infos
            where  p.IsEnabled == true
            group p by …

我有一张产品表

产品:

ProdID  | ProdName
     1  | shirt
     2  | pants

尺寸表:

SizeID | Size
     1 | small
     2 | med
     3 | large

订单表

OrderID   | ProdID    |  SizeID    | Qty
 1        |    1      |   1        |  4
 2        |    1      |   1        |  3
 3        |    1      |   2        |  2
 4        |    2      |   1        |  1
 5        |    2      |   3        |  1

我如何得到这样的结果:

ProdName | Size    | Total qty ordered   (group by product and size …

如何使用flash as3计算字符串中的大写字母数？

例如

var thestring = "This is The String";

应该返回int 3

谢谢
