How do I set a Type TSomething at run time in C#?

I am writting a function that takes a parameter and that parameter requires a Type of TEntity. I want to be able to pass it a specific Type during runtime but I am having trouble getting it to compile:

public LoadOperation LoadQuery(EntityQuery<???> query)
        {
            LoadOperation loadOperation = DomainContext.Load(query,LoadBehavior.MergeIntoCurrent, false);
            return loadOperation;
        }

The code that wont compile looks like this:

EntityQuery<Person> q = DomainContext.GetPerson();
LoadQuery(q);

I have tried different things to m开发者_StackOverflow中文版ake this work but am at a loss. What do I need to do?

Depending on what your DomainContext.Load() function looks like:

public LoadOperation LoadQuery<T>(EntityQuery<T> query)
{
    LoadOperation loadOperation = DomainContext.Load(query,LoadBehavior.MergeIntoCurrent, false);
    return loadOperation;
}

And then still use it exactly like you did before:

EntityQuery<Person> q = DomainContext.GetPerson();
LoadQuery(q);

The type system should infer you mean the LoadQuery<Person>() version of the function from the argument.

Unfortunately, I suspect this will also mean some revision to the aforementioned Load() function.
