.net 将字典数据转换成xml 字符串， 以及传参至存储过程后如何取值

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;
