我一直在尝试使用C#在我的ASP.NET站点中创建一个Instant Messaging应用程序.我开始了解XMPP,它是GChat用于即时消息传递的协议.我想知道如何在我的ASP.NET应用程序中实现它.对此提供的任何见解将非常感谢.

谢谢.

我从网上获得了一个页面响应,它有类似的字符串"Lluís Quílez".但我明白了"Lluís Quílez".那么如何将其更改回"Lluís Quílez"C#？

谢谢.

我使用以下代码在xml列中的sql数据库中保存了一个数据集.

XmlDataDocument dd = new XmlDataDocument(dataset);

并将此xml文档作为sql参数传递使用

param.value = new XmlNodeReader(dd);

XML就像

<NewDataSet><SubContractChangeOrders><AGCol>1</AGCol><SCO_x0020_Number>001</SCO_x0020_Number><Contract_x0020_Number>006</Contract_x0020_Number><ContractID>30</ContractID><ChangeOrderID>211</ChangeOrderID><Amount>0.0000</Amount><Udf_CostReimbursableFlag>false</Udf_CostReimbursableFlag><Udf_CustomerCode

我试着按如下方式阅读它

using (SqlConnection con = new SqlConnection("Server=#####;Initial Catalog=#####;User ID=####;Pwd=########"))
        {
            using (SqlCommand com = new SqlCommand("select * from dbo.tbl_#####", con))
            {
                using (SqlDataAdapter ada = new SqlDataAdapter(com))
                {
                    ada.Fill(dt);
                    MemoryStream ms = new MemoryStream();
                    object contractXML1 = dt.Rows[0]["SCOXML1"]; 
                    System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bf = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
                    bf.Serialize(ms, contractXML1);
                    ms.Seek(0, SeekOrigin.Begin);
                    ds.ReadXml(ms);
                }
            }
        }

我收到以下错误

根级别的数据无效.第1行,第6位.

有任何想法吗？

更新

我将代码更改为以下内容.我能够获得数据集的结构,其中包含所有表格.但不是数据.

using (SqlConnection con = …

我对正则表达式并不熟悉.我有一个字符串,我需要使用正则表达式提取特定值.这是字符串

CN=ReportingGroup {b4f3d644-9361-461e-b604-709fa31f2b9e},OU=DOM USERS,DC=domain,DC=com

我想得到CN和OU的值,即"ReportingGroup {b4f3d644-9361-461e-b604-709fa31f2b9e}"和"DOM USERS"

从上面的字符串.我如何为此构建正则表达式模式？

我有两个字符串 StringA、StringB。我想生成一个唯一的字符串来表示这一对。

IE

f(x, y) 对于每个 x、y 和 f(x, y) = f(y, x) 应该是唯一的，其中 x、y 是字符串。

有任何想法吗？

我正在解析几个XML文件,其中我将日期时间值保存为文本.我无法找到下面的格式 -

20110123T233356,00-05

我都尝试DateTime.Parse与DateTimeOffset.Parse二者均失败.我也尝试在这里和这里没有运气的几个地方识别字符串.

我正在开发一个WCF服务应用程序,它对XML文件进行了大量的操作.在我开始循环节点,元素,属性和所有其他东西之前,我想知道XmlNode,XmlElement,XmlDocument和所有其他Xml相关类上可用的有用函数,它们可以用来代替循环.

例如,您可以使用CopyTo(string[]).将List转换为数组.

谢谢.

我正在寻找以下列方式创建节点的水平树视图控件 -

希望你得到设计.

我从事多个ASP.NET/SharePoint C#项目.在开发过程中,我们会使用精心评论来更好地理解.但在我想要发布版本之前,我想要隐藏所有注释(而不是删除它们).有没有VS插件或一些工具来做到这一点？

如何使用CSS删除CSS中的注释Regex.Replace()？

注意 - 我无法在C#中使用此处提到的正则表达式 - 正则表达式来删除CSS注释.
