如何檢查Asp.Net WebForms會話大小

Question

我需要在某些時刻檢查會話大小。我怎樣才能做到這一點？

我不得不試圖創建掠影自定義選項卡，但會話對象總是空：

public override object GetData(Glimpse.Core.Extensibility.ITabContext context) 
{ 
    var result = new List<string[]> { new[] { "Object", "Number of bytes" } }; 

    HttpContextBase context1 = context.GetHttpContext(); 
    HttpSessionStateBase session = context1.Session; 

    if (session != null) 
    { 
     long totalSessionBytes = 0; 
     BinaryFormatter b = new BinaryFormatter(); 
     MemoryStream m; 
     foreach (var obj in session) 
     { 
      m = new MemoryStream(); 
      b.Serialize(m, obj); 
      result.Add(new[] { obj.ToString(), m.Length.ToString() }); 
      totalSessionBytes += m.Length; 
     } 

     result.Add(new[] { "Total", totalSessionBytes.ToString() }); 
    } 
    else 
    { 
     result.Add(new[] { "Session", "Null" }); 
    } 
    return result; 
} 

我也試過這樣：

但我無法找到任何IGlimpsePlugin接口。

取決於你如何實現你的標籤

• 實施Glimpse.Core.Extensibility.ITab
• 從Glimpse.Core.Extensibility.TabBase，Glimpse.Core.Extensibility.TabBase<T>或Glimpse.AspNet.Extensibility.AspNetTab繼承

，你必須確保你實現/重寫RuntimeEvent ExecuteOn屬性，以便它運行在RuntimeEvent.BeginSessionAccess或RuntimeEvent.EndSessionAccess

因爲默認情況下它是RuntimeEvent.EndRequest這對於會話訪問來說太晚了
