Question

如何更改<代码>System.Collections.Generic.List<T> to a System.Data.Linq.EntitySet<T>?

Answer 1

Don tink 你可以将List<T>改为。实体Set<T>,但您可将名单内容列入实体。。

var list = new List<string> { "a", "b", "c" };
var entitySet = new EntitySet<string>();
entitySet.AddRange(list);

此处为:

public static EntitySet<T> ToEntitySet<T>(this IEnumerable<T> source) where T : class
{
    var es = new EntitySet<T>();
    es.AddRange(source);
    return es;
}

Answer 2

var list = new List<string> 
{ 
    "element1", "element2" 
};
var entitySet = new EntitySet<string>();
entitySet.AddRange(list);
