Question

Can I access the this object in my extension methods?

So far this is what I have:

void Main() {

    IQueryable<DataContextTable> list = DataContextTables.First().NewMethod(this);

}

public static class ExtensionMethods {

    public static IQueryable<DataContextTable> NewMethod(this DataContextTable table, TypedDataContext context) {
        return context.DataContextTables.Where(item => item.SomeProperty == true).AsQqueryable();
    }

}

as you can see I still need to pass the TypedDataContext as parameters to my extension methods. Is there any other way I can do this?

Answer 1

I created a static member of type TypedDataSet and “initialize” it in the Main() function with this.

void Main() {

    ExtensionMethods.Context = this;
    IQueryable<DataContextTable> list = DataContextTables.First().NewMethod(this);

}

public static class ExtensionMethods {

    public static TypedDataSet Context;

    public static IQueryable<DataContextTable> NewMethod(this DataContextTable table) {
        return Context.DataContextTables.Where(item => item.SomeProperty == true);
    }

}
