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???

XML

 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;

Solution 1

You can use the Union operator like this:

C#

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();

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

Hope this helps.

You will need to explain (edit your original question) exactly what classes are stored in the lists and what result you are trying extract for me to be able to help further.

Solution 3

- 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...
