我可以用我当前正在做的方式建立一本字典,但我想知道是否有更好更快的方法.我正在尝试使用LINQ SelecMany语句,但遇到了麻烦.

var replyChildren = reply.Children[0];
Dictionary<int, string> slowLog = new Dictionary<int, string>();
for (int i = 0; i < replyChildren.Children.Count(); i++)
{
    var ithReplyChildren = replyChildren.Children[i];
    for (int j = 0; j < 4; j++)
    {
        if (j == 3)
        {
            var jthReplyChildren = ithReplyChildren.Children[j];
            for (int k = 0; k < jthReplyChildren.Count; k++)
            {
                serverInfo += jthReplyChildren.Children[k].TextData; //+ "::";
            }
            break;
        }
        serverInfo += ithReplyChildren.Children[j].TextData + ":";
    }
    slowLog.Add(i, serverInfo);
    serverInfo = "";
}

回复将有孩子在里面(第0个元素)然后在那些将有孩子的内部,依此类推.第二个for循环将只有4个孩子,第四个将不得不更深入一步并得到孩子们.

我有一个存储过程，可以删除超过特定日期的所有数据。但我想添加该功能，以便它一次只删除 1000 行。

我有这样的东西

USE [databaseName]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[LogTrim]
                       (
                          @DaysToKeep             INT = 28
                          --@Blocks               INT = 1000 --??
                       )
AS
