我如何正确地在HttpSessionStateBase中模拟HttpSessionStateBase？
我如何正确地在HttpSessionStateBase中模拟HttpSessionStateBase？
提问于 2011-08-09 00:04:41
我从下面的示例中设置了这个模拟会话对象：How to MOQ an Indexed property
/// <summary>
/// HTTP session mockup.
/// </summary>
internal sealed class HttpSessionMock : HttpSessionStateBase
{
private readonly Dictionary<string, object> objects = new Dictionary<string, object>();
public override object this[string name]
{
get { return (objects.ContainsKey(name)) ? objects[name] : null; }
set { objects[name] = value; }
}
}一些产生错误的示例代码..。
var mockSession = new HttpSessionMock();
var keys = mockSession.Keys;错误：方法或操作未实现。
我需要实现Keys属性，但无法创建KeysCollection对象。
做这件事最好的方法是什么？
编辑:解决方案
最后，我根据给出的答案更改了HttpSessionMock。这就是我最后的下场。(我还添加了对System.Linq的引用)。
internal sealed class HttpSessionMock : HttpSessionStateBase
{
private readonly NameValueCollection objects = new NameValueCollection();
public override object this[string name]
{
get { return (objects.AllKeys.Contains(name)) ? objects[name] : null; }
set { objects[name] = (string)value; }
}
public override NameObjectCollectionBase.KeysCollection Keys
{
get { return objects.Keys; }
}
}注意:这个模拟会话只存储字符串，而不是对象。

我发现了原始方法和接受的解决方案的结合，既允许存储对象，也可以实现键属性：
public class HttpSessionMock : HttpSessionStateBase
{
private readonly NameValueCollection keyCollection = new NameValueCollection();
private readonly Dictionary<string, object> objects = new Dictionary<string, object>();
public override object this[string name]
{
get
{
object result = null;
if (objects.ContainsKey(name))
{
result = objects[name];
}
return result;
}
set
{
objects[name] = value;
keyCollection[name] = null;
}
}
public override NameObjectCollectionBase.KeysCollection Keys
{
get { return keyCollection.Keys; }
}

单程：
internal sealed class HttpSessionMock : HttpSessionStateBase
{
public override NameObjectCollectionBase.KeysCollection Keys
{
get { return _collection.Keys; }
}
private readonly NameValueCollection _collection = new NameValueCollection();

更新:下面是来自KeysCollection框架的.NET源代码，供您参考：
public class KeysCollection : ICollection, IEnumerable
{
// Fields
private NameObjectCollectionBase _coll;
// Methods
internal KeysCollection(NameObjectCollectionBase coll)
{
this._coll = coll;
}
public virtual string Get(int index)
{
return this._coll.BaseGetKey(index);
}
public IEnumerator GetEnumerator()
{
return new NameObjectCollectionBase.NameObjectKeysEnumerator(this._coll);
}
void ICollection.CopyTo(Array array, int index)
{
if (array == null)
{
throw new ArgumentNullException("array");
}
if (array.Rank != 1)
{
throw new ArgumentException(SR.GetString("Arg_MultiRank"));
}
if (index < 0)
{
throw new ArgumentOutOfRangeException("index", SR.GetString("IndexOutOfRange", new object[] { index.ToString(CultureInfo.CurrentCulture) }));
}
if ((array.Length - index) < this._coll.Count)
{
throw new ArgumentException(SR.GetString("Arg_InsufficientSpace"));
}
IEnumerator enumerator = this.GetEnumerator();
while (enumerator.MoveNext())
{
array.SetValue(enumerator.Current, index++);
}
}
// Properties
public int Count
{
get
{
return this._coll.Count;
}
}
public string this[int index]
{
get
{
return this.Get(index);
}
}
bool ICollection.IsSynchronized
{
get
{
return false;
}
}
object ICollection.SyncRoot
{
get
{
return ((ICollection) this._coll).SyncRoot;
}
}
