How do I Find bindingSource by Name?

I have many bindingsource in my winform, and I wanna change my gridview's dataSource dynamically，so I wanna Get bindingSource by there's name. I have find following code to find all bindingSource from my winform,

    private IEnumerable<Component> EnumerateComponents()
    {
        return from field in GetType().GetFields(
                    BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic)
               where typeof(Component).IsAssignableFrom(field.FieldType)
               let component = (Component)field.GetValue(this)
               where component != null
               where component.ToString().Contains("Windows.Forms.BindingSource")
               select component;
    }

After I got my BindingSourceList I wanna filter one of them by name, But I don't know how to do,please help me, thanks~

    IEnumerable<Component> BindingSourceList = EnumerateComponents();
    //I wonder find a bindingSource by name, but it doesn't work
    BindingSource bb = BindingSourceList.find(a=>a.name=="myBindingSource");
