Question

Class

public class Job
{
    pub         


        

Answer 1

If all of your jobs are of same type (e.g. Job) you can simply create a list of that type:

List> x = new List>();
x.Add(new Job());

However, if you want to mix jobs of different types (e.g. Job and Job) in the same list, you'll have to create a non-generic base class or interface:

public abstract class Job 
{
    // add whatever common, non-generic members you need here
}

public class Job : Job 
{
    // add generic members here
}

And then you can do:

List x = new List();
x.Add(new Job());

If you wanted to get the type of a Job at run-time you can do this:

Type jobType = x[0].GetType();                       // Job
Type paramType = jobType .GetGenericArguments()[0];  // string
