How to set type of generic method in runtime

Is something like that possible:

int testvar = 0;
var query = PrimaryDataSource.AsEnumerable().Where(r => 
                r.Field<testvar.GetType()>("col") == testvar);

But I don't want this:

int testvar = 0;
if (testvar is int)
{
    var query = PrimaryDataSource.AsEnumerable().Where(r => 
                    r.Field<int>("col") == testvar);
}

Just don't use Field to get the value; get it as an object:

var query = PrimaryDataSource.AsEnumerable().Where(r => 
    object.Equals(r["col"], testvar));

The whole point of using generics is to have static typing when you know the type involved statically. Since you don't, there's no benefit to using it.
