I just simply trying to add items with values to a combobox from a XML file at runtime in a
windows application. The code below does not work in windows development.
//Code:
XDocument xDoc = XDocument.Load(#"Yourxmlfile.xml");
var query = from xEle in xDoc.Descendants("publication")
select new ListItem(xEle.Element("name").Value,
xEle.Attribute("tcmid").Value);
cmbLoad.ValueMember = "value";
cmbLoad.DisplayMember = "text";
cmbLoad.DataSource = query;
In the above code the ListItem class is not available for winforms so i couldn't proceed.
The above code works fine with web application.
Any help?
You can achieve that using this code:
XDocument xDoc = XDocument.Load(#"Yourxmlfile.xml");
var query = from xEle in xDoc.Descendants("publication")
select new { value = xEle.Element("name").Value, text = xEle.Attribute("tcmid").Value };
var list = query.ToList();
comboBox1.ValueMember = "value";
comboBox1.DisplayMember = "text";
comboBox1.DataSource = list;
ListItem doesn't exist for WinForms. I used an anonymous class above and converted it to a list which I can use as a source for a combo box.

I want to achieve the same code logic using Linq basically or re factoring the code would be great.
List<PublisherDto> listOfMappedPublishers = new List<PublisherDto>();
listOfPublishers.ForEach(pub =>
{
PublisherDto publisher = new PublisherDto();
publisher.ApiKey = pub.ApiKey;
publisher.Name = pub.Name;
publisher.Password = pub.Password;
listOfMappedPublishers.Add(publisher);
});
return listOfMappedPublishers;
You can use Select and ToList as follow:
List<PublisherDto> listOfMappedPublishers = listOfPublishers.Select(i=> new PublisherDto()
{
ApiKey = i.ApiKey,
Name = i.Name,
Password = i.Password
}).ToList();

I want to refactor the code, I need to make this code dynamic, how to do that, see below part?
public class Trv34
{
public string CustomerNumber
public string ProductName
}
Models.Trv34[] itemTrv34 = new Models.Trv34[3]
itemTrv34[0] = new Models.Trv34 {CustomerNumber ="1", ProductName="p1"}
itemTrv34[1] = new Models.Trv34 {CustomerNumber ="2", ProductName="p2"}
itemTrv34[2] = new Models.Trv34 {CustomerNumber ="3", ProductName="p3"}
request.VODB.Trv34= new Models.Trv34[] {
itemTrv34[0],
itemTrv34[1],
itemTrv34[2],
};
I want to replace this part with something dynamic instead
itemTrv34[0],
itemTrv34[1],
itemTrv34[2],
The easiest way that comes to mind is to use Linq:
request.VODB.Trv34 = itemTrv34.ToArray();

The first 3 lines of code works fine..
How can I do the same when using object initializer ?
// works
Customer MyCustomerx = new Customer();
MyCustomerx.Location[0].place = "New York";
MyCustomerx.Location[1].place = "France";
// problem here
List<Customer> MyCustomer = new List<Customer>
{
new Customer() { Name= "Me",Location[0].place = "New York" }
}
There's no equivalent of that code within object initializers - you can't specify indexers like that. It's slightly unusual that it works even directly... I'd expect to have to add to a Locations property, rather than there being two already available which I could set an unconventionally-named property on. For example, this would be idiomatic:
Customer customer = new Customer {
Name = "Me",
Locations = {
new Location("New York"),
new Location("France")
}
};
(I'd probably put the name into a constructor parameter, mind you.)
You could then use that within a collection initializer, of course.

I created a tree , but now (Inside the code) , I want to Move entire tree to its leftChild and assign a new tree to rightChild and change the root's node !
as shown in picture below:
In C# if it's possible.
From your image I guess you're making a binary tree. All a tree is when you get down to it is a series of nodes.
So assuming you have a node class like this.
public class MyBinaryNode
{
MyBinaryNode LeftChild;
MyBinaryNode RightChild;
MyBinaryNode()
{
LeftChild = null;
RightChild = null;
}
MyBinaryNode(MyBinaryNode leftChild, MyBinaryNode rightChild)
{
LeftChild = leftChild;
RightChild = rightChild;
}
}
All you'd have to do is something like this;
MyBinaryNode B = new MyBinaryNode();
MyBinaryNode C = new MyBinaryNode();
MyBinaryNode A = new MyBinaryNode(B,C); //This is your current tree
MyBinaryNode E = new MyBinaryNode();
MyBinaryNode D = new MyBinaryNode(A,E); //This is how you make the one in your Image

I have got a requirement like I have got list of strings and I got dropdownlist items now we need to check whether the dropdownlist has all items in the give list of strings or not and i need to return the bool condition ...
for that purpose i have done like this ....
public static bool GetMacthedItems(DropDownList ddllist1, DropDownList ddllist2, string MatchedItem1, string MatchedItem2, string MatchedItem3)
{
bool results =true;
List<String> list1 = new List<String> {MatchedItem1, MatchedItem2, MatchedItem3};
if (ddllist1.SelectedValue.ToString() == MatchedItem1 && (list1.Any(x => x.Contains(ddllist2.SelectedValue.ToString()))))
{
results = false;
}
return results;
}
but the above condition is checking like whether the dropdownlist selected value is in that list or not ....
i want entire like all items in dropdownlist are in that list or not
would any one pls help on this ....
var allContained = ddlCountry.Items.Cast<ListItem>().Select(item => item.Value).All(item => lst.Contains(item.ToString());
Try this - for performance it will stop iterating once the condition is broken and return false by using a combination of All with Contains.
