Question

I have a simple object like this

public class Test
{
   public string Name {get; set;}
}

Later I have List<Test> tests

And then I have a method which does something with a Test object in the List.

private void DoSomething(Test test)
{
   //do some serious stuff here!
}

Then in the applciation, this Test objects will be populated in a TreeView and after user clicks them they will be passed to the method above. At the moment I find selected treenode like this:

string name = selectedNode.Text;

foreach(Test test in tests)
{
   if (test.Name = name) DoSomething(test);
}

So the idea is, I cant figure out a way to use LINQ in the parameter of the method instead of doing that boring foreach loop.

this.DoSomething(from x in tests where x.Name = "What I need to pass" select x)

what is wrong?

Thanks!

Answer 1

this.DoSomething(tests.FirstOrDefault(x=>x.Name=="What I need to pass"))
