如何使用Linq的查詢語法來返回隨機記錄？

類似下面的TSQL語句：

select top 10 * from sometable ORDER BY NewID() 

Answer 1

您可以使用Guid.NewGuid()與LINQ

var results = db.sometable.OrderBy(r => Guid.NewGuid()).Take(10); 

或查詢語法：

var results = (from s in sometable orderby Guid.NewGuid() select s).Take(10); 

Answer 2

這應該是等價的：

var query = 
    (from s in sometable  
    orderby Guid.NewGuid() //Ordering by Guid.NewGuid() is the same as newid() 
    select s) 
    .Take(10);    //This cannot be done in query syntax.
