Thanks by advance

Answer 1

您不能向现有查询中“添加”一个子句，因为查询本身是不可变的-但您可以创建一个新查询，该查询是现有查询，但带有一个附加子句：

IQueryable<Foo> newQuery = oldQuery.Skip(20);

Answer 2

var query = FunctionThatReturnsIQueryable().Skip(20);

Answer 3

As long as you haven't enumerated over the query, you can always add clauses. The clauses are only executed as soon as you get the results (eg with for each ).
You could do something like GetSomeIQueryable().Skip(20) . That returns you a new query that includes your skip clause.
