返回两个linq列表 [英] to return two linq Lists

问题描述

大家好，

我再次在LINQ中遇到新问题.一些专家可以告诉我，我有一个< tblcontact>列表.和另一个列表< tbladdress>.是否可以将两者全部归还?还是解决这种情况的其他方法???

HI all,

I am again here with a new problem in LINQ.can some expert tell me that i have a list<tblcontact> and another list<tbladdress>. is it possible to return both these together? or is some other way to solve this situation???

 List<ContactsInfo> lstID = new List<ContactsInfo>();
 FileStream streams = new FileStream(System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath + "ClientInfo\\" + "tblContacts.xml", FileMode.Open, FileAccess.Read);
 StreamReader readers = new StreamReader(streams);
 System.Xml.Serialization.XmlSerializer serialize = new System.Xml.Serialization.XmlSerializer(typeof(List<ContactsInfo>));
 XmlReader xmlreaders = new XmlTextReader(streams);
 lstID = (List<ContactsInfo>)serialize.Deserialize(xmlreaders);

 List<AddressInfo> AddID = new List<AddressInfo>();
 FileStream streamAdd = new FileStream(System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath + "ClientInfo\\" + "tblAddress.xml", FileMode.Open, FileAccess.Read);
 StreamReader readerAdd = new StreamReader(streamAdd);
 System.Xml.Serialization.XmlSerializer serializeAdd = new System.Xml.Serialization.XmlSerializer(typeof(List<AddressInfo>));
 XmlReader xmlreaderAdd = new XmlTextReader(streamAdd);
 AddID = (List<AddressInfo>)serializeAdd.Deserialize(xmlreaderAdd);



return lstID;

我想一起返回lstID和AddID.该怎么做??

在此先感谢

i want to return lstID and AddID together. how to do that??

thanks in advance

推荐答案

您可以像这样使用Union运算符:

You can use the Union operator like this:

List<int> a = new List<int>() { 1, 2, 3 };
              List<int> b = new List<int>() { 4, 5, 6 };
              List<int> c = a.Union(b).ToList();

这将为您提供所有6个数字的列表.这适用于所有基本数据类型，例如字符串等.

希望这会有所帮助.

This will give you a list with all 6 numbers. This works with all basic DataTypes such as string etc.

Hope this helps.

-创建
的对象 列表(对象)
或
列表(<<用于ContactInfo和AddressInfo的通用类型说一个接口>)
-然后将两个对象(lstID和AddID)都添加到创建的对象中
-并返回对象.

希望这对您有帮助...

- Create an object of
List(Of Object)
or
List(Of <common type used for ContactInfo and AddressInfo say an interface>)
- then add both the objects (lstID and AddID) into the object created
- and return the object.

Hope this helps...
