Grouping by property value and writing group members
- by Will S
I need to group the following list by the department value but am having trouble with the LINQ syntax. Here's my list of objects:
var people = new List<Person>
{
new Person { name = "John", department = new List<fields> {new fields { name = "department", value = "IT"}}},
new Person { name = "Sally", department = new List<fields> {new fields { name = "department", value = "IT"}}},
new Person { name = "Bob", department = new List<fields> {new fields { name = "department", value = "Finance"}}},
new Person { name = "Wanda", department = new List<fields> {new fields { name = "department", value = "Finance"}}},
};
I've toyed around with grouping. This is as far as I've got:
var query = from p in people
from field in p.department
where field.name == "department"
group p by field.value into departments
select new
{
Department = departments.Key,
Name = departments
};
So can iterate over the groups, but not sure how to list the Person names -
foreach (var department in query)
{
Console.WriteLine("Department: {0}", department.Department);
foreach (var foo in department.Department)
{
// ??
}
}
Any ideas on what to do better or how to list the names of the relevant departments?
