c# – 静态属性/功能的性能

HttpCache中有一个使用频繁的对象,可以通过页面实例(Service.aspx)中的属性访问.现在我想知道是否更好地使它静态,因为无论如何HttpCache在应用程序中共享.

我决定使其静态的主要原因是因为引用更简单(Service.dsRMA vs.((Service)Page).dsRMA).

我知道静态功能和线程安全可能出现的问题.

感谢您的时间.

之前：

C#

public ERPModel.dsRMA dsRMA {
    get {
        if (Cache("DS_RMA") == null) {
            Cache("DS_RMA") = new ERPModel.dsRMA();
        }
        return (ERPModel.dsRMA)Cache("DS_RMA");
    }
}

VB

Public ReadOnly Property dsRMA() As ERPModel.dsRMA
    Get
        If Cache("DS_RMA") Is Nothing Then
            Cache("DS_RMA") = New ERPModel.dsRMA
        End If
        Return DirectCast(Cache("DS_RMA"),ERPModel.dsRMA)
    End Get
End Property

后：

C#

public static ERPModel.dsRMA dsRMA {
    get {
        if (HttpContext.Current.Cache("DS_RMA") == null) {
            HttpContext.Current.Cache("DS_RMA") = new ERPModel.dsRMA();
        }
        return (ERPModel.dsRMA)HttpContext.Current.Cache("DS_RMA");
    }
}

VB

Public Shared ReadOnly Property dsRMA() As ERPModel.dsRMA
    Get
        If HttpContext.Current.Cache("DS_RMA") Is Nothing Then
            HttpContext.Current.Cache("DS_RMA") = New ERPModel.dsRMA
        End If
        Return DirectCast(HttpContext.Current.Cache("DS_RMA"),ERPModel.dsRMA)
    End Get
End Property
