Question

I have three tables I’m getting info from: User, Field, FieldUserInput. I already know the userId which is what I use to find out what fields the user has input. Then I want to get the value of those fields that the user has input in FieldUserInput.

I first wrote this query in plain old sql but I want to use LINQ as much as possible since that’s why I use Entity Framework.

SELECT fielduserinput.field_idField, fielduserinput.userInput, fielduserinput.time
FROM fielduserinput
WHERE fielduserinput.userId = @userId

Any suggestions as to how I would write this in LINQ?

Considering you have a datasource filled with data.

var matchingRows = from rows in fielduserinput.AsEnumarable()
                   where string.compare(rows["userId"].ToString(),userID)==0
                   select rows;
