Cannot access non-static member of outer type 'LINQPad.User.TypedDataContext'

[Deleted User] · February 2013

The following error has stymied me.

Cannot access non-static member of outer type 'LINQPad.User.TypedDataContext' nested type 'UserQuery.MyOriginalClass'

What does this mean and how do I fix it?

Normally, anything types that you define end up as nested types, because LINQPad wraps everything that you enter into a class definition. You can tell LINQPad to extract the classes and define them as non-nested by adding the following to the beginning of your query:

#define NONEST

Fixing the previous problem opened a new issue. I'm confident the query works in a live program. How do you query a database from a class method? The specific error that appears is 'Could not find an implementation of the query pattern for source type 'LINQPad.User.GenericTableName'. 'Select' not found.

var query = from gtn in GenericTableName
select sa.Asset.Name;

Is the method part of another class that you're writing? If so, you'll need to pass in the typed data context as follows:

    void Main()
    {
        Foo.Test (this);
    }
    
    class Foo
    {
        public static void Test (TypedDataContext data)
        {
            data.Customers.Dump();
        }
    }

If the method isn't part of a separate class, just make sure it's an instance method and it will work just fine:


    void Main()
    {
        Test();
    }
    
    void Test()
    {
        Customers.Dump();
    }
