Entity framework自定义字段实现思路

ublic class MyModel
{
    public int MyModelID            { get; set; }

    public string FixedProperty1    { get; set; }
    public string FixedProperty2    { get; set; }

    // This is a navigation property for all your custom properties
    public virtual ICollection<CustomProperty> CustomProperties  { get; set; }
}

public class CustomProperty
{
    public int CustomPropertyID      { get; set; }

    // This is the name of custom field
    public string PropertyName       { get; set; }
    // And this is its value
    public string PropertyValue      { get; set; }

    // FK reference and navigation property to your main table
    public int MyModelID             { get; set; }
    public virtual MyModel MyModel   { get; set; }
}
