1,.net 将字典数据转换成xml 字符串

   Dictionary<string,DateTime> dicUserLocked = new Dictionary<string,DateTime>();    

      if (!dicUserLocked.ContainsKey(model.UserName))
     {
            dicUserLocked.Add(model.UserName,System.DateTime.Now);
     }
    // ....
    dicLockedUsers.ToXml<string,System.DateTime>().ToString()

2,传参至存储过程后如何取值

var tmpList =
this.GeneratesqlSpParameter(column_LockedUsers,(dicLockedUsers == null) ? null : dicLockedUsers.ToXml<string,System.DateTime>().ToString());
tmpList.sqlDbType = System.Data.sqlDbType.Xml;
parameters.Add(tmpList);

  
	declare @X xml
	set @X=convert(xml,N'<Dictionary><Item><Key><string>jones.zhang</string></Key><Value><dateTime>2015-04-16T10:24:36.4149457+08:00</dateTime></Value></Item></Dictionary>')
	SELECT @X
 
	declare @XmlHandle int
	EXEC sp_xml_preparedocument @XmlHandle OUTPUT,@x;
		select * from OPENXML (@XmlHandle,'/Dictionary/Item',2)
		WITH (
			[A] [varchar](200) 'Key/string',[B] [DateTime] 'Value/dateTime'
		);
 
      EXEC sp_xml_removedocument @XmlHandle;
