Solution 1

I think the Guid.NewGuid().ToString() as explained here Guid.NewGuid Method[^] may be used instead of newid() in the LINQ query

Hey VJ Reddy, I am generating Random records so i use NewID() in SQL same as LINQ Query Random.next().
What is use of Guid.NewGuid.ToString().
Not working ur method. reply me

Guid.NewGuid().ToString() generates a globally unique ID which can be thought of a Random combination of alpha numeric characters.
For eg. the following code
for(int i=0; i<10; i++)
Console.WriteLine (Guid.NewGuid().ToString());

generates the following output.

//a5d1f707-8e9b-491f-abd3-4ba755bb5c9d
//4331afda-e252-41ce-bb4a-f713bca8e1f2

The NEWID explained here http://msdn.microsoft.com/en-us/library/ms190348.aspx generates an ID like
6F9619FF-8B86-D011-B42D-00C04FC964FF

So Guid.NewGuid().ToString() can be used to generate a Random ID in C# and can be used in LINQ like NEWID used in Sql Server

In my above Query:
DisplayBy=1,2,3,4,5,6,7,8,9,...(Four Time Repeated this value in table)

Your query is worked when select the records(Shuffled Totally All records).
But I need Shuffled with grouping, like based on DisplayBy field.
within DisplayBy field shuffled together each...
