ADO.NET :: LINQ To Entities Doesn't Recognize The "Int32 Parse(System.String)" Method
Dec 14, 2010
I am using Entity Framework to contact my data base. as part of my web code I am using Linq to entities, and I want to determine the number of elements in an anonymous type list. I can't get it to work, I get the exception: "LINQ to Entities does not recognize the method 'Int32 Parse(System.String)' method, and this method cannot be translated into a store expression."
var questItem = from chapters in context.TestChapter
from questions in context.Question
where chapters.ID == int.Parse(Request.QueryString["id"])
where questions.TestChapterID == chapters.ID
select questions.ID;
int numOfSteps = questItem.Count();
how can I get it to work?

I have a GridView and on a row being deleted I trigger the GridView1_RowDeleting sub, but I receive an error "LINQ to Entities does not recognize the method 'System.Web.UI.WebControls.TableCell get_Item(Int32)' method, and this method cannot be translated into a store expression." Code is:
Private Sub GridView1_RowDeleting(sender As Object, e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
' The deletion of the individual row is automatically handled by the GridView.
Dim dbDelete As New pbu_housingEntities
' Remove individual from the bed.
Dim remove_bed = From p In dbDelete.Beds _
Where p.occupant = GridView1.Rows(e.RowIndex).Cells(3).Text _
Where p.room = GridView1.Rows(e.RowIndex).Cells(6).Text _
Where p.building = GridView1.Rows(e.RowIndex).Cells(5).Text _
Order By p.id Descending _
Select p
remove_bed.First.occupant = ""
dbDelete.SaveChanges()
' Increase number of open spaces in room.
Dim update_occupancy = From p In dbDelete.Rooms _
Where p.room1 = GridView1.Rows(e.RowIndex).Cells(6).Text
Where p.building = GridView1.Rows(e.RowIndex).Cells(5).Text _
Select p
update_occupancy.First.current_occupancy = update_occupancy.First.current_occupancy - 1
dbDelete.SaveChanges()
End Sub
The specific line erroring out is: remove_bed.First.occupant = ""

I receive this error message: LINQ to Entities does not recognize the method 'System.Guid GetUserId()' method, and this method cannot be translated into a store expression. This is my code:
DB.Users user = db.Users.FirstOrDefault(u => u.Id == BOL.GetUserId());
BOL.GetUserId() returns a GUID of the current logged-in user (and this works works).
How can I make this LINQ code line work? Or, what is the shortest alternative? In the mean time I found out that there is a difference between LINQ to SQL and Entities. I use Entities because of the TailspinSpyworks example... but my code is using LINQ to SQL. My current solution is to use a var:
var userId = BOL.GetUserId();
DB.Users user = db.Users.FirstOrDefault(u => u.Id == userId);
Is this a good solution? And, is the execution time of Entities faster than SQL?

I am building a web application in asp.Net 4.0 and entity framework. I am trying to retrieve a list of products based on a collection of id's. I first gather all the id's in a collection and then pass it to the linq query. I am trying to get a functionality similar to the IN clause in SQL. The problem seems to be with the Contains() method in the Linq to entities query. Here is my Linq code:

Given a string like:
Token A^*!%~Token B^*!%~Token C^*!%~Token D^*!%~Token E
Write a method that parses the string into a series of substrings where the delimiter between the substrings is ^*!%~ and then reassembles the strings and delimiters into a single new string where each of the substrings is in the reverse order from the original string. The method must return the final string. The expected output would be:
Token E^*!%~Token D^*!%~Token C^*!%~Token B^*!%~Token A

I have a solution which uses Linq to SQL Data Classes to acced the db. I have a project for my domain objects in my solution, which is a class library and has the dbml file. When I set up the dmbl using the wizard, Visual Studio created anapp.config file on that project with the connection string. It also creatting asettings file with the same info. I've noticed that if I change the connection string in the settings file, the app.config gets updated, which is the expected behaviour.
However, I'm having a problem when I deploy my web site to the production server. I already set the app.config file's Build Action to "Content", and also set Copy to ouput directory to "Always". Nevertheless, when I install the web site and change the connection string in the app.config file, it still takes the old connection string, so obviously I get an error. I've found that it only works if I change it with in Visual Studio and then compile, but of course that's not an optimal solution, because any change in the production db server would mean I have to change my project's assembly, thus generating a new version.
What do I have to configure so that the assembly takes the connection string form my app.config file directly after I deploy?

I'm having trouble writing what should be a simple sub-query using LINQ to Entities. I have two tables: Customers and Orders that have a relation on the CustID field. Not all Customers have a record in the Orders table, while some have mutiple records. In traditional SQL, you could write the query like this: SELECT * FROM Orders where CustID IN (SELECT CustID FROM Customers) I know this could be done as a JOIN in both SQL and L2E, but my actual query is more complex (about 8-9 joins), so I am hoping to find a L2E sub-query equivalent. Something like this:
[Code]....
I know LINQ to Entities does not support the " IN " clause, so I am looking for something that will work in its place.

I'm really new to ASP.Net and for a school project we have to create a login form. Now I have managed to create a login with LINQ doing the following:
[Code]....
And in my html page:
protected void Test_Click(object sender, EventArgs e)
{
if (Class1.Controle(Convert.ToInt32(txt1.Text), txt2.Text))
[Code]....
I was thinking something amongst those lines, but I can't call p.GebruikerWachtwoord. So I'm guessing this is completely wrong.I hope somebody can help me figure this out, and I apologise for the poor explanation, English isn't my native language.

I'm trying to follow the demo from this link to add a jqGrid to an MVC app.
I have a table named Companies that I'm trying to display in a grid. A Company simply contains an ID and a Name.
I'm running into an error in my controller function:
public JsonResult DynamicGridData(string sortIndex, string sortOrder, int page, int rows)
{
int pageIndex = Convert.ToInt32(page) - 1;
int pageSize = rows;
var companies = companiesRepository.Companies.OrderBy(sortIndex + " " + sortOrder).Skip(pageIndex * pageSize).Take(pageSize);
//Error here
...
}
I'm getting an error on the line that is calling OrderBy():
The type arguments for method 'System.Linq.Enumerable.OrderBy(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly.
I really have no idea what the error means, and I haven't been able to find an explanation. I'm not sure what is causing this error on a simple OrderBy function.

I'm using a GridView control to edit data in a MySQL database.
I've created the C# code behind but I'm having trouble pulling back the parameter from a radiobutton control to populate an Int32 field in the database. I'm getting "Input string not in correct format"This is the particular bit (amongst a host of others of the same type) that is causing the problem:
cmd.Parameters.Add("?yes", OdbcType.Int).Value = (Convert.ToInt32(((RadioButton)GridView2.Rows[i].FindControl("edYes")).Text));
